Title: Speed control device for elevator
Inventor: OHIRA KATSUMI
IPC: B66B1/30
Filed: 1990-01-22
Abstract: PURPOSE:To shorten an address position arithmetic processing time by providing a means in which a distance signal, obtained by multiplying a distance signal, obtained by integrating a speed command signal generated in an electronic computer, by a predetermined arithmetic period by a predetermined coefficient, serves as an advance position. CONSTITUTION:Arithmetic operation of an advance mode 1 is performed up to the time T1 where a speed obtains a rated speed VLR. That is, unless an advance position arithmetic counter TC is the time T1 or more, an integrated value SPAT is obtained by SPAT+PATNXdt (PATN: speed command signal, dt: arithmetic period), and an advance position ADVN is obtained by arithmetic operation of SPATXZ. That is, concerning the advance position up to the time T1, two times a distance signal, obtained by integrating the speed command value, serves as the advance position. Concerning a distance in the case of determining a stop during running at a rated speed, the advance position ADVN is obtained by SYNC (present position) + DSLR (minimum deceleration running amount).

Title: Method and equipment for optical transmission
Inventor: TSUSHIMA HIDEAKI
IPC: H04B10/07
Filed: 1986-01-24
Abstract: PURPOSE:To attain optical transmission with low noise and high quality by controlling an electric field rotating angle of an optical signal so that noise energy is minimized or selecting a rotating angle maximizing optical signal energy out of plural rotating angles minimizing the noise energy. CONSTITUTION:A part of light Ic projected from a polarization dependent optical element 2 is converted into an electric signal by a photoelectric converter 4 and outputted as an electric signal 5 and a part of the electric signal 5 is inputted to a noise/signal energy measuring instrument 6 to measure the energy of the noise and signal. When the noise energy is increased with time, a control device 8 controls an electric field rotating device 3 so that the noise energy is reduced and also controls the electric field rotating angle so that the signal energy is maximized. Even if the optical fiber transmitting the optical signal 1a is disturbed, optical transmission with low noise and high quality can be obtained.

Title: Recording method
Inventor: MIURA MASAYOSHI
IPC: B41J2/385
Filed: 1989-01-20
Abstract: PURPOSE:To correct the adverse influence of the shift of a line or dot position to be inconspicuous by a method wherein, when a regular shift occurrs on a line or dot position by one recording element, the thickness or dot diameter of a recording element adjacent to said recording element is changed. CONSTITUTION:In the case that all 24 values of line thickness by 24 nozzles are equal to each other, the shift of the 7th nozzle toward the 8th nozzle in arrangement increases a gap between the 6th and 7th lines as well as decreases a gap between the 7th and 8th lines, thus resulting in the occurrence of a stripe pattern. In this case, the thickness values of the 7th and 8th lines are decreased, and the thickness value of the 6th line is increased. When a recorded image is observed a distance of distinct vision apart after the application of such a correction, the stripe pattern caused by the positional shift of the 7th nozzle is visually inconspicuous. In addition, the thickness of the line can be controlled in such a manner as the magnitude of an ink liquid drip 34 is controlled under the control of the amplitude of the output of a drive circuit 32 of a recording head 31.

Title: Ultrasonic plastics working equipment
Inventor: NAKAJIMA TAKASHI
IPC: B29C65/08
Filed: 1984-01-25
Abstract: PURPOSE:To facilitate the manufacture of a working equipment by connecting a driving horn squarely to the center of a disc-shaped tool horn to form chips projected at the vibration loop position point on the opposite surface and at the portion of a pedestral corresponding thereto. CONSTITUTION:A driving horn 7 is connected squarely to the center of a disc- shaped tool horn 6 to apply longitudinal vibration thereto, a circular deflecting vibration is generated. So, when chips 5 are formed projected circularly at the position point 8 of the loop, namely, side of the deflecting vibration, the longitudinal vibration of the driving horn 7 can be utilized most efficiently. Thus, the proper selection of the thickness and diameter of the tool horn 6 and the frequency of the vibration enables the forming of a working equipment at a low cost which permits the formation of a fusing surface of large single, double and triple circles on the plastics and a spot caulking on the plastics in one process.

Title: High temperature filter for cooling water of fuel cell
Inventor: KANEKO MASAO
IPC: C02F1/42
Filed: 1985-01-28
Abstract: PURPOSE:To remarkably decrease heat loss by treating untreated water having condensed copper and iron with an ion exchange resin at low temperature, and oppositely washing a filter material with cooling water obtained by adsorbing filtering. CONSTITUTION:Part of cooling water entered a filter 21 flows out from an untreated water outlet 26 and its temperature is decreased with a heat exchanger 9 then the water is treated with an ion exchange resin tower 10 at low temperature. Since the untreated water flows along the surface of filter material 36 of the filter 21 and flows out from the filter with removing part of copper and iron trapped on the surface of filter material 36, the water which flowed out from the filter contains much copper and iron before entering the filter. When the filter material 36 is washed, a valve 31 is opened and nitrogen gas is supplied to a cooling water reservoir 25 and the cooling water enters the filter 21 through a valve 24 and a cooling water outlet 23, and flows within the filter material in an opposite direction to filtering. Thereby, copper and iron trapped in the filter material is removed and the water flows out from the untreated water outlet 26.

Title: Plasma cvd method and apparatus therefor
Inventor: TERASAKI MASATO
IPC: H01L21/205
Filed: 1995-01-30
Abstract: PURPOSE: To prevent the adhesion of dust to a cathode by generating plasma between the electrodes in a reactive gaseous atmosphere and forming a CVD film on a substrate, then turning off the cathode voltage and grounding the cathode. CONSTITUTION: The cathode 6 and an anode 15 are arranged in parallel in an inside vessel 10 of the reaction treatment vessel 1 of this plasma CVD apparatus and the substrate 16 is placed on this anode 15. After the inside of the inside vessel 10 is evacuated to a vacuum by a discharge pipe 17, reactive gases are supplied from a gas introducing pipe 8 into the inside vessel. The reactive gases are then supplied into the space between the cathode 6 and the anode 15 by many diffusion holes 9 disposed at the cathode 6. A high-frequency voltage is simultaneously impressed between the cathode and the anode by a high-frequency power source 22 to generate the plasma in the space between the cathode and the anode and to form the CVD film by cracking of the reactive gases on the substrate 16.  The voltage impressed on the cathode is thereafter turned off and the cathode is grounded, by which the static electricity on the cathode is removed and the dust sticking thereto is removed. The attraction of the substrate to the cathode and the consequent adverse influence thereof on transportation are thus prevented.

Title: Method of making resin-applied sheet having smooth surface
Inventor: SHIMADA YOSHIO
IPC: B05C11/04
Filed: 1982-01-28
Abstract: PURPOSE:To easily and efficiently produce a resin-applied sheet having a smooth surface, by applying synthetic resin to a running base sheet material, and immediately bringing the free end of a suspended flexible resin film into contact with the surface of the uncured resin. CONSTITUTION:A fixed amount of resin is continuously applied to a roll-shaped base sheet material 1 by carrying the base sheet material 1 through a space between a press roll 4 and a gravure roll 3. The base sheet material 1 is then transferred through a turning roll 5. Before the resin is caked by drying or cured, the sheet material 1 comes in contact with one end of a resin film 8 hung at a proper position so as to make the surface of the applied resin on the sheet 1 uniform and smooth. The resin liquid is supplied to the gravure roll 3 through a pick-up roll 2 dipped in a cell 6 contg. the resin liquid. Said film is made of a flexible material inactive to the resin liquid, e.g. polyester, PE or PP, and the thickness of the film is generally at about 5mu-2mm..

Title: Flow rate control valve
Inventor: NAGASAKA KENZO
IPC: F16K31/126
Filed: 1993-01-28
Abstract: PURPOSE:To reduce the dispersion of a controlled flow rate by screw pairing a control valve to the upper end part of a valve stem so as to be movable in the axial direction of the valve stem, and making a rod abut on the connecting face of a regulating member having a connecting face to abut on the lower end part of the rod for interlocking them. CONSTITUTION:A regulating member 40 is positionally regulated in a state where the lower case 21a of the lower half part of the case 21 of an actuator 20 is fixed to a totally closed control valve 10 with bolts 22. The regulating member moves axially upward or downward in the upper end part of a valve stem 15 with its rotation. A position to which the regulating member 40 is moved is regulated by measuring an axial distance between a referential portion, for instance the lower face of the lower case 21a, and a connecting face 42. Namely, a part interlocking the rod 31 of a lift sensor 30 is regulated to a fixed position. Thus the dispersion of the output voltage of a soft sensor 30 at the reference position of the control valve can be controlled, and flow rate control being little in dispersion therefore becomes practicable.

Title: Manufacture of electrode for crystal oscillator
Inventor: YOSHIDA HIROHIKO
IPC: H03H3/02
Filed: 1979-02-07
Abstract: PURPOSE:To obtain a perfect side surface electrode for the crystal tuning fork of the miniature etching type, by securing the curved travelling property to the evaporation material and thus ensuring the uniform thickness for the evaporation film. CONSTITUTION:Mask 9 featuring slit width b1 smaller than slit width b of crystal tuning fork 7 is attached to fork 7 which is pulled out in many units in alignment through etching from a sheet of the crystal wafer along with main surface electrode 3 formed each. Such fork 7 is then evaporated in the atmosphere of the inactive gas featuring the pressure of 10<-4>-10<-2> torr. Thus particle 10 of the evaporation material collides against molecule 11 of the inactive gas. As a result, the uniform sticking of the evaporation material can be secured even at the corner areas on surface 2 of crystal oscillator 7 where the evaporation material is hitherto hard to stick, thus obtaining perfect electrode 4.

Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent the error in exposure control based on the error in the detection of a brightness value in the case where an AF sensor is used commonly as an AE sensor for spot photometry. SOLUTION: The distance measuring sensor of a distance measuring section 5 is commonly used as the photometric sensor for the spot photometry at the center of a screen. The image data obtd. by this distance measuring sensor having spectral sensitivity in an IR region is stored into the basis part/reference part data areas 125a, 125b of a memory 125. The spot photometric data is calculated by using the image data of the basis part data area 125a by a photometric arithmetic section 122. A photometric section 4 has a photometric sensor having spectral sensitivity in a visible region. The photometric data for the entire part of the photographic screen is detected from the output of the photometric sensor. The exposure control is executed by the photometric data alone when the photometric data is smaller than the prescribed value estimated to be an artificial light source.  The exposure control is executed by the photometric data and the spot photometric data when the data is above the prescribed value. The error in the exposure control is prevented by not using the spot photometric data under the artificial light source of the low reliability of the photometric value.

IPC: B66B11/04
Filed: 1990-01-25
Abstract: PURPOSE:To improve driving efficiency by employing a secondary stator comprising a stator body having a large number of core fixing holes in the longitudinal direction with intervals and a core placed in the core fixing holes. CONSTITUTION:Each secondary stator 15 comprises a stator body 17 having a large number of core fixing holes, i.e. slits 17a, made in the longitudinal direction with intervals and a core 18 inserted into the slit 17a. When ac AC current is fed to the winding of a primary mover 2, flux 19 is produced as shown by arrows and an eddy current 20 is induced in the secondary stator 15. The flux 19 and the eddy current 20 interact to produce thrust for driving the primary mover 2. At this time, the eddy current flows concentrically through the stator body 17 having low electric resistance. Since the part, through which useless eddy current making no contribution to the production of thrust flows, is limited correspondingly, random flow of useless eddy current is reduced.
