IPC: G03F7/30
Filed: 1979-03-10
Abstract: PURPOSE:To uniformly coat a resist and enhance the accuracy of a semiconductor producing process by feeding inert gas to the back side of a substrate or the like to be coated with the resist to prevent adhesion of the liquid agent to the back side by scattering it horizontally. CONSTITUTION:An upper portion of spinner head 2 set on rotary shaft 1 is provided with vacuum chuck 3, and silicon wafer 4 is held by suction of the portion. Head 2 has inert gas blow holes 5 at its upper edge portion to blow up inert gas toward the back side of the substrate under a predetermined press. When resist 6 is dropped onto the substrate fixed on head 2 by vacuum suction, an excess of the liquid agent is removed horizontally with inert gas currents and discharged from discharge outlet 7. Thus, the liquid agent such as resist 6 can be coated uniformly without adhesion to the back side.

IPC: G01F1/66
Filed: 1986-02-12
Abstract: PURPOSE:To enable measurement even when the ultrasonic wave propagation time is larger than the pulse width of the oscillation frequency, by providing two ultrasonic wave converters and a forward/backward switching circuit. CONSTITUTION:An output frequency (f) continuously oscillated form an oscillation circuit 10 is controlled intermittently through a counter circuit 20 and a gate circuit 30. Ultrasonic wave converters T and R convert an output of the circuit 30 into an ultrasonic wave signal and does the ultrasonic wave signal into an electrical signal respectively. A forward/backward switching circuit K changes over the propagation direction of the ultrasonic signal with respect to flow velocity V by switching the circuit 30 over to the converters T and R.

Title: Trigger pulse formation circuit
Inventor: IENAKA MASANORI
IPC: H03K5/1534
Filed: 1978-03-15
Abstract: PURPOSE: To obtain a large amount of the trigger output even with increment of the load resistance by connecting the transistor to the output terminal of the trigger pulse in order to lower the output impedance.  
     CONSTITUTION: In case the input signal exists at terminal IN, the voltage delivered to output terminal OUT features the higher one between the collector voltage of transistor 16 and the emitter voltage of transistor 22 in case no connection is given between the collector of 16 and the emitter of 22. This means that the logic sum has been obtained between the collector voltage of 16 and the emitter voltage of 22, and thus the output trigger synchronized with the input pulse can be obtained. For integration of the circuit, the electrostatic capacity must be reduced for capacitor 21 and the resistance 20 most be increased. In this connection, transistor 22 is used as the emitter follower in order to prevent the fact that the output impedance increases to cause the shortage of the output.

Filed: 1995-02-17
Abstract: PURPOSE: To provide a compact fuel pressurizing device by which fuel can be pressurized higher. CONSTITUTION: In a header 3 serving as a housing for a fuel pressurizing device 1, a recess part 3b is formed on the outside wall in one end part, on the same axis with a through hole 3a, and a pressure accumulating chamber 41 is formed of the recess part 3b and a lid member 40 to be screwed into the recess part 3b.

Title: Dc-dc converter
Inventor: TOYA HIROKAZU
IPC: H02M3/335
Filed: 1990-02-08
Abstract: PURPOSE:To prevent a large transient current from flowing into transistors in a DC-DC converter by providing a choke coil having a core on which are wound four windings with the same number of turns. CONSTITUTION:A choke coil L1 is constituted by applying windings N1-N4 to a single core. All the winding turns of the respective windings N1-N4 are identical. In a normal operation, a circuit is so constituted as to make the windings N1 and N4 or the windings N3 and N2 of the choke coil L1 have subtractive polarity directions and, further, the winding turns of the windings N1-N4 are identical. Therefore, the choke coil L1 plays no operational role. On the other hand, concerning a mode wherein a transistor Q1 is switched from a conducting state to a non-conducting state in a short time and a charge current showing a large peak value is applied to a transistor Q2, the circuit is so constituted as to make the windings N3 and N4 of the choke coil L1 connected to additive polarity directions. As a result, the peak value of the charge current can be suppressed to a low value.

Title: Measuring device for inner diameter of fine tube
Inventor: TAKAHASHI NORIO
IPC: G01B11/08
Filed: 1981-02-27
Abstract: PURPOSE:To perform reliable measurement of an inner diameter of fine tubes without  adjustment, by a method wherein laser light passing through a fine tube is detected by a photo detector, meanwhile, laser light from a beam splitter is detected to produce a  reference voltage, and the measurement of the inner diameter is obtained by a fine  tube inner diameter detecting signal processor through a comparision amplifier. CONSTITUTION:A part 24 of a laser light bundle, radiated from a laser tube 2, is  fetched by a beam splitter 21, and a part 6, advancing in a beeline, forms a parallel  light beam 6' after passing through a lens 12. A transparent fine tube 11 to be measured is irradiated with light 6''' passing through a polarizing mirror 8 and a collecting lens 10. Light beam passing through the fine tube is collected by a lens 10' and is  detected by a photo detector 13. A detecting voltage Vo produces an input of a comparision amplifier 15. Meanwhile, laser light 24, so fetched, is detected by a photo  detector 22 to produce a reference voltage V's via an amplifier 23. Irradiated light to fine tube is scanned by a polarizing mirror 8, and this obtains a signal passing through both the thick wall part and inner diameter part of the fine tube. As a result, simply  through a change in a laser light source, both the reference voltage V's and the detecting voltage Vo fluctuate to perform a compensation.

Title: Double convergence mass spectrograph
Inventor: KATOU YOSHIAKI
IPC: H01J49/02
Filed: 1983-02-25
Abstract: PURPOSE:To reduce measuring time as a whole by restricting the magnetic field sweeping range in proportion to an electric field voltage. CONSTITUTION:A computer 14 sets an electric field voltage value E0 to allow the detection of normal ions m1. A sweep signal is fed to magnetic field 5 with a magnetic field sweeper 10. In response to a magnetic field sweep starting signal START from the computer 14, the magnetic field 5 increases gradually from 0. A signal E' (a voltage ratio E/E0) is compared with a signal I' (a current ratio I/I0). As the current I increases, the current ratio signal I' also increases and when it exceeds the signal E', a sweep stop signal STOP is outputted. Responding to this, the computer 14 feeds a new set value one step lower than the previous set electric field value E0. In this manner, the operation of sweeping the magetic field by lowering the set electric field value one step at a time is repeated until the set electric field value is almost 0. This can realize a magnetic field sweeping system restricted by the set electric field voltage value thereby enabling the desired data collection time being reduced.

Abstract: PURPOSE: To remove the pickling efficiency difference between both sides of stainless steel strip, by supplying air bubbles compulsively toward the under side of the strip which passes between electrodes equipped in the pickling soln.  
     CONSTITUTION: In an electrolytic pickling apparatus, where stainless steel strip 4 runs nearly horizontally between electrodes 2, 3 equipped at upper and lower part in the electrolyte contained in a tank 1, a compressed-air-supplying pipe 5 is arranged at a position in the tank 1 lower than the strip 4 passing between the electrodes 2, 3, and the air bubbles spouting out through air-jetting openings 6 made on the upper surface of the pipe 5 is made to collide against the under side of the strip 4. The spouted air bubbles collide with the under side of the strip 4 and ascends continuously to the surface of the electrolyte while stirring the electrolyte, so that air bubbles or generated gas hardly stays at the under side of the strip 4, hence the pickling efficiency difference between both sides of the strip 4 is removed.
