Title: Warning device
Inventor: MIURA KATSUO
IPC: G08B23/00
Filed: 1988-07-21
Abstract: PURPOSE:To obtain the warning device of high reliability by ringing again a ringing warning means immediately and generating warning even when another sensor detects a trouble warning condition and executes operation continuously before a trouble is recovered to be normal in case that warning operation is stopped by a stop switch. CONSTITUTION:When a stop switch 9 is pushed down and opened from a closing condition after a warning operation condition is obtained, a ringing warning means 9 goes to a not-exciting condition and stops the warning operation regardless of an auxiliary (a) contact 13 in the closing condition so as to keep a self-holding condition. When a second warning sensor 3 detects the trouble warning condition and executes the operation continuously before the trouble to be related with the warning sensor 2 is recovered to be normal in this stop condition, a ringing warning means 7 is rung and outputs the warning sanely as a case that the first sensor 2 is operated. Simultaneously, a warning indicator 1 is turned on. When the warning sensors 2 and 3 are recovered to be normal, since an electro-magnetic relay 4 for warning goes to not-exciting, auxiliary (a) contacts 14 and 15 go to a turning-off condition and warning indicators 10 and 11 are turned off.

Title: Integrated memory
Inventor: SCHOENIGER SABINE
IPC: G11C11/409
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To perform a control at a relatively long distance from a function part without necessitating special control lines by allowing a control unit to perform the adjusting of the first potential state of data pair lines and the adjusting of at least one second potential state of the data pair lines and allowing a detector unit to start a prescribed control function when the second potential state of the pair lines is generated. SOLUTION: An integrated memory has a control unit C adjusting potentials on data pair lines DL, the inverse of DL and a detector unit D generating an enable signal EN. As a result, when two lines of the data pair lines D, the inverse of DL have low levels, the enable signal EN also has a low level to block transistors T3, T4 and a differential amplifier SA is separated from the data pair lines DL, the inverse of DL independently from an activating signal AKT to be inactivated. Thus, the inactivating of the differential amplifier SA can be performed via the data pair lines D, the inverse of D and individual enable lines can be omitted.

Title: Thick-film thermal head
Inventor: SUGAWA TOSHIO
IPC: B41J2/335
Filed: 1988-07-21
Abstract: PURPOSE:To prevent a sticking phenomenon of the title device by providing projections in a protective insulating material layer in the vicinity of a heating resistor. CONSTITUTION:On the surface of a glass layer 2 on an alumina substrate 1, an Au electrode 3 and a heating resistor 4 are respectively formed with a required pattern, and projections 6 made of an insulating material and having nearly the same height as the heating resistor 4 are formed adjacent to the heating resistor 4 on the both sides thereof. If the insulating material forming the projections 6 is made of the same glass matrial as a glass layer 5 serving as a protective insulating material layer, the both are coincident with respect to thermal expansively; in this manner, a thermal breakage hardly occurs and the value of the resistance 4 of the heating resistor 4 never fluctuates. Furthermore, the glass layer 5 is printed and baked so as to cover the projections 6 and the heating resistor 4. Here, when the glass layer 5 is printed, a glass paste penetrates between the heating resistor 4 and the projections 6, and the glass melts at the baking. In this manner, the glass has a flat surface, thus having a large radius of curvature; thereby eliminating a sticking phenomenon at the time of heat generation.

Title: Light interference type optical fiber sensor
Inventor: YOSHIDA AKIAKI
IPC: G01R15/24
Filed: 1982-10-18
Abstract: PURPOSE:To realize simple constitution by generating light incident to an optical fiber and regarding its reflected light from a semitransparent mirror as reference light and light which is transmitted through the semitransparent mirror and reflected by the reflecting mirror of an optical fiber for a sensor as signal light, and detecting interference between both lights. CONSTITUTION:Laser projection light from a laser light source 1 is passed through a beam splitter (BS) 2 and an optical fiber 3, and the light reflected by the semitransparent mirror 5 is incident to a photodetector 8 by a BS2 as the reference light. The light transmitted through the semitransparent mirror 5 is passed through the optical fiber for the sensor which is stored in a hollow container 9 and reflected by the reflecting mirror 7 to enter the photodetector 8 as the signal light through the BS2. The reference light and signal light interfere with each other and temperature variation of the optical fiber 6 for the sensor is detected as a phase shift of interference light. Consequently, the constitution of an optical fiber interferometer is simplified.

Title: Liquid crystal lens with variable focal length
Inventor: HIBINO KOETSU
IPC: G02B3/00
Filed: 1991-07-23
Abstract: PURPOSE:To provide the variable focal length liquid crystal lens in simple structure which eliminates the need for a polarizing plate. CONSTITUTION:The liquid crystal lens is constituted by stacking a liquid crystal cell 1 which is formed in a lens shape and has liquid crystal molecules oriented in one direction, a 1/4-wavelength plate 2, and a reflecting plate 3 in order. When light made incident on the liquid crystal cell 1 is split into two mutually orthogonal polarized components, i.e., a polarized component which is parallel to the orientation direction of the liquid crystal molecules and a polarized component which is orthogonal to it, the polarized component parallel to the orientation direction of the liquid crystal molecules is extraordinary light and varies in refractive index continuously from a value for the extraordinary light to a value for ordinary light by electric field application. When this polarized component is made incident on the 1/4-wavelength plate 2, it becomes circular polarized light, which becomes anticlockwise circular polarized light through the operation of the reflecting plate 3; when this light is made incident again on the 1/4-wavelength plate 2, a polarized component crossing the direction at the time of the incidence is obtained, so even if the light is made incident again on the liquid crystal cell 1, the light is not affected by the effect of focal length variation. The polarized component which is orthogonal to the orientation direction of the liquid crystal cells, on the other hand, is reverse.

Title: Driver of stepping motor
Inventor: SHINOHARA ISATO
IPC: H02P8/14
Filed: 1989-07-17
Abstract: PURPOSE:To automatically recover the failure of a switch when a home position switch(HPSW) is not recovered as it is in a contact condition by moving a carriage which carries a recording head to the HPSW again and letting the carriage collide with the HPSW again. CONSTITUTION:A carriage moves in a returning direction by a one - two phase excitation at a pulse width (t0). After an HPSW signal is detected and the HPSW is held for a holding time (t1), the carriage moves by (n1) steps at the pulse width (t0) in a scanning direction and a printing starting position (software home position, SHP) is determined. The HPSW returns to as original position by the movement of the carriage in the scanning direction. In this case, whether the HPSW is ON or OFF is judged and, in case of ON, the carriage is moved in the returning direction until the carriage collides with the HPSW again.

Title: Method of forming resist pattern
Inventor: MAEDA TETSUYA
IPC: G03F7/20
Filed: 1991-07-23
Abstract: PURPOSE:To form a fine resist pattern by forming an uneven part on a surface of a resist, so forming a step of the resist surface that a phase of an exposure light wavelength is just deviated by a special wavelength, then exposing the entire surface with a parallel light ray by an exposure unit and developing it. CONSTITUTION:A desired base board 1 is coated with positive type photoresist 2, and a desired pattern is transferred from a mask 20 by a contraction exposure unit, etc. It is developed to form a step on the surface of the resist. Then, the entire surface is exposed with a parallel light ray having a wavelength lambda. In this case, the step of the resist surface is so set that the phase of the exposure wavelength is just deviated by 1/2 wavelength. Then, when it is developed, the resist so remains as to be disposed along a line of the step of the resist surface, and a very fine line pattern can be formed. Thus, a patterning of a finer width or space than the wavelength at the time of entire surface exposure, i.e., the wavelength of a single wavelength parallel beam which can be formed, can be performed.

Filed: 1983-09-30
Abstract: PURPOSE:To accelerate start and the stability of optical output and maintain luminous efficiency with high efficiency by always locating a principal amalgam or a principal metal body at the uppermost section of a luminous tube and providing an auxiliary metal body for forming auxiliary amalgam or amalgam at the high temperature section in the vicinity of an electrode. CONSTITUTION:When optical output is transferred to the stable state, amalgamate mercury is all evaporated and the intra-tube mercury vapor pressure is controlled by the vapor pressure that is determined by the temperature of the principal amalgam formed by a principal metal body 21, that is, the principal metal body 21. In this case, since the metal body 21 for forming the principal amalgam is housed in a luminous tube 5 so as to freely move, the temperature difference between an auxiliary metal body 22 in the vicinity of an electrode 11 and the metal body 21 located in the coolest section can be increased even when the fluorescent lamp unit is lit making a metal cap 2 face either upward or downward. As a result, when the optical output is transferred to the stable state, the mercury vapor pressure of a luminous tube 5 at stability is controlled to the vapor pressure that is determined by the temperature of the principal metal body by setting the peak temperature so as to evaporate the auxiliary amalgam mercury.
