Title: Device for change in winding of very fine wire
Inventor: KOYATANI YOSHIO
IPC: B65H55/04
Filed: 1985-03-30
Abstract: PURPOSE:To enable tension applied to a very fine wire to be automatically adjusted when a winding is newly started by providing a device with both a means which sets tension to be applied to the very fine wire in numbers of steps, and a timer which switches over the value set by the above mentioned means after the set time will elapse. CONSTITUTION:When a winding of a very fine wire is newly started, high tension is set to meet requirements just after a new winding has started with a high tension setting unit 30 activated. Simultaneously, low tension is also set to meet requirements after the set time which is set by a timer circuit 33 in advance, will elapse with a low tension setting unit 31 activated. Subsequently, a feed motor 36 and the like is started with a starting button depressed. This causes the set voltage Vh which corresponds high tension to be applied to a tension control circuit 34 permitting control voltage Vc which corresponds to high tension, to be applied to an electromagnet 19. After the time set in the timer circuit 33 has elapsed, the set voltage Vl which corresponds to low tension, is applied to the tension control circuit 34.

Title: Optical disk and its production
Inventor: TATEWAKI MASAYUKI
IPC: G11B7/24024
Filed: 1986-03-26
Abstract: PURPOSE:To improve the adhesive strength of two substrates by reducing the pressure in the contact part of signal parts of the two substrates and uniting the two substrates to one body, thereby maintaining the airtightness in the reduced pressure part. CONSTITUTION:The air pressure in a room is reduced to the pressure lower than the atmospheric pressure while the parts 1a1 of the substrates 11, 12 removed of mask layers 7, 8 are in approximate contact with each other and the parts 1b1 removed of the mask layer 8 are on approximate contact with each other. The air pressure in this stage is, for example, 10<-2>-10<-3>(Torr). The air pressure in the rugged parts of the signal parts 3 formed with metallic films 4 is thereby reduced. Since the airtightness is maintained while the pressure in the signal parts 3 is made lower than the atmospheric pressure in the above-mentioned manner and therefore, the disk surface is pressed by the large atmospheric pressure when the disk is used in the ordinary atm. The adhesive strength of the substrates 11 and 12 is thereby made larger and the product having high reliability is obtd.

IPC: H01J49/04
Filed: 1994-03-11
Abstract: PURPOSE: To make an LC/MS(liquid chromatograph/mass spectrometer) interface of high efficiency possible even on a solvent of high moisture content. CONSTITUTION: A LC/MS system 100 comprises a particle beam generator 110 which effectively handles the aqueous input. Helium is made to pass through the organic liquid in a bubble generator 116. The organic liquid is kept at a temp. lower than 4 deg.C. The obtained mixture of the helium and the organic substance vapour, is used as a dispersion gas in the particle beam generator 110. The dispersion gas is brought into contact with an eluate mainly composed of water, before it is introduced to an atomizer 130, to decompose the eluate to the degree of liquid-drop. The solvent in the liquid-drop is vaporized in a desolvent chamber 134. Helium, the organic substance vapour and the solvent vapour are removed from the analyzed substance particle beam by a momentum separator 140.  Then the analyzed substance particle beam is sent to a mass spectrometer 104, to perform the identification and determination on each sample component. Accordingly, the signal strength can be extraordinarily improved, in comparison with the similar system in which the organic substance vapour is not included in the dispersion gas.

Title: Digital modulating device
Inventor: SAKAZAKI YOSHIHISA
IPC: H04L25/49
Filed: 1993-03-26
Abstract: PURPOSE:To decrease maximum pulse width and to obtain DC free characteristics after reduced components are sufficiently suppressed. CONSTITUTION:A code conversion ROM 2 converts input data into a 14-bit code by using tables A-F. The tables A-F use codes satisfying d=1, k=6, 1<s0<=6, and e0-<=4. A ROM 4 finds the CDs of the output code and the number of '1's. A DSV calculator 5 finds DSV from the CDS and d waveform polarity decision circuit 6 finds the waveform polarity of the last code. A decoder 7 selects the tables A-F on the basis of the DSV, waveform polarity, and the terminal bit of the last code. The DSV is suppressed without making the DSV stay at a non-zero value. Consequently, the maximum pulse width is made small by decreasing the number of successive '0's to six and the DC free characteristics after reduced components are sufficiently suppressed are obtained.

Title: Ultrasonic type flow meter
Inventor: ODA MINORU
IPC: G01P5/00
Filed: 1979-05-29
Abstract: PURPOSE:To obtain the flow meter with high precision, high response speed and good stability of temperature by using a signal received by the ultrasonic wave transmitting and receiving element as a sample hold signal of a lamp signal. CONSTITUTION:Signals phiA, phiB, which are obtained by halving the frequency of an output signal MSTR of a master controller 4, and another signal phiGT of a fixed width, which is triggered by the fall of MSTR, are produced and the ultrasonic pluse generators 4, 5 are triggered by the phiA and phiB. The ultrasonic signal Sg emitted from the ultrasnoic wave transmitting and receiving element 3, which is caused by the phiA, is received by the transmitting and receiving element 2, and an output signal is provided through an amplifier 7 and a peak selector 9. The signal sample-holds the output of the lamp signal 13 that is triggered by the fall of the phiGT. The held value is the difference obtained by subtracting a transfer time TMSTR from another one TA between the transmitting and receiving elements 3 2. Since the outputs of both the held value and the other one by a sample hold circuit 16, which is similarly obtained from the phiB, through a subtracter 20 are proportional to the flow rate of the fluid, the flow rate can be measured from the said values.

Title: Image pickup optical system
Inventor: UZAWA TSUTOMU
IPC: H04N5/335
Filed: 1990-03-19
Abstract: PURPOSE:To make an incident light beam incident vertically on the image pickup surface of a small-sized image pickup element at its peripheral part by providing positive refracting power to at least one of optical elements in an optical element group. CONSTITUTION:This image pickup optical system is an image pickup optical system such as a video camera, an electronic still camera, and a fiber scope and at least one optical element in the optical element group has the positive refracting power. For example, the projection surface of an optical low-pass filter 2 is formed as a lens part 2a which has positive refracting power. Therefore, the light beam which is projected by a photographing lens 1 and made incident on the peripheral part of the image pickup surface of the image pickup element 3 is refracted positively by the lens part 2a and made incident on the image pickup surface almost vertically. Consequently, the constitution of the image pickup optical system which uses image pickup elements having a regular picture element array and removes moire fringes by the optical low-pass filter is small in size and simple and the system becomes telecentric. Namely, the light beam which is made incident on the peripheral part of the image pickup surface of the image pickup element is made incident on the image pickup surface almost vertically.

Title: Part mounting device
Inventor: CHIKAHISA NAOICHI
IPC: H05K13/00
Filed: 1990-03-19
Abstract: PURPOSE:To remove a component, which has missed the chance to be inserted, automatically and proceed with routine component mounting operation without any need for human attendance by detecting whether or not a component insertion section has penetrated through a substrate by means of an insertion detection sensor. CONSTITUTION:When a component 1 held with an insert unit A is installed to a substrate 2, an insertion detection sensor 12 installed to an anvil unit B detects whether or not an insertion section of the component 1 has penetrated through a substrate 2. This detection makes it possible to judge the presence of the mounted component 1 before processing to the end of the insertion section of the anvil unit B. When non-insertion is detected, the insert unit A, which is still holding the component, is adapted to move and take away the component, which has missed the chance to be inserted, from the substrate 2 automatically. It is, therefore, possible to proceed with routine component mounting operation without any human attendance.
