Title: Thin film forming device
Inventor: SATO TATSUYA
IPC: C23C14/32
Filed: 1990-04-06
Abstract: PURPOSE:To form a thin film with a high adhesive property on a substrate without heat resistance by covering an electron gun with a slit having an aperture and making the thermions from the electron gun incident on a target via this aperture. CONSTITUTION:A prescribed pressure is attained by gaseous Ar in a vacuum chamber 1 and the thermions are released from the electron gun 30 consisting of a filament 7, an auxiliary grid 8 and an anode 9 and are made incident on the space between a pair of deflecting coils 10. The electrons deflected therein pass the aperture 12a of the slit 12 and head toward a grid 6 where the electrons are made into positive ions by collision against the Ar molecules and are diffused to the surface of a target 21 by the electric field between the grid and the target, by which the target is sputtered at a high speed. The particles from the ionized target 21 pass the grid 6, by which the particles are accelerated to collide against the substrate 100 and to stick thereto. The thin film is formed with the extremely good adhesive property on the substrate 100 in this way and the radiation of the filament 7 of the electron gun 30 is shut off by the slit 12; therefore, the temp. rise of the substrate 100 is decreased. Even the substrate 100 without heat resistance is thus usable.

Title: Optical switch
Inventor: FUKUNAGA HIROSHI
IPC: G02B26/08
Filed: 1986-04-21
Abstract: PURPOSE:To make it possible to set optimum shifting position of a condenser at high accuracy in a short time by making a controller store and hold optimum number of pulses and control rotation angle of a stepping motor. CONSTITUTION:For instance, when switching a condenser 6 to the first optical fiber 1 side, electric pulses are given gradually to a stepping motor 11 to rotate the condenser 6 slowly. At this time, electric pulses are given, for instance, from a keyboard added to a microcomputer. Optimum rotational position of the condenser 6 is determined to make the output value of a light detector 2 maximum, and a controller 14 stores and holds the optimum number of pulses when the optimum rotational position is arrived at. Similarly, optimum rotational position of the condenser 6 for the second - tenth optical fibers 1 is found and optimum number of pulses at that time is stored and held. Thus, rotation angle of the stepping motor 11 is controlled according to stored and held value, and the condenser 6 is switched automatically to the optimum rotational position.

Title: Burner for furnace
Inventor: FUJII YUUICHI
IPC: F23N5/00
Filed: 1981-06-16
Abstract: PURPOSE:To equalize temperature distribution in the furnace by an arrangement wherein a control is effected so as to increase or decrease the flow speed of a combustion gas so that the moving amount of the combustion gas can be maintained at a constant value even if the combustion amount changes, thereby constantly securing recirculation or convection over the entire zone in the furnace regardless of the combustion amount. CONSTITUTION:A first and a second fuel supply chambers 7 and 8 are supplied with fuel from fuel guns 9, 14... and with combustion air from inlets 7b and 8b by means of fans 13 and 18. The chambers 7 and 8 mix thus supplied fuel and air and inject the resultant mixture into the furnace 1 through injection ports 7a and 8a. The injection port 7a injects a high speed mixture, whereas the injection port 8a injects a low speed mixture, the former accelerating the latter. The mixture burns advancing toward a backward wall 2b of the furnace 1 and then returns from the backward wall 2b and goes out of a smoke passage 4. If the combustion amount in the furnace 1 is relatively small, the combustion rate at the injection port 7a is increased to increase the moving amount of the combustion gas, whereas if the combustion amount is relatively large, the combustion rate is decreased. Thus the overall moving amount of the combsution gas is maintained substantially at a constant value.

Title: Detector
Inventor: NODA YOSHIAKI
IPC: G01V8/12
Filed: 1982-05-28
Abstract: PURPOSE:To detect whether a body is present or not accurately all the time by inputting a maximum photodetector signal obtained for every sample cup to a level discriminating circuit without fail. CONSTITUTION:A turntable TT rotates as shown by an arrow and the lower part of a sample cup DC1 is positioned on the optical path between a projector TL and a photodetector RL at time t0. Then, a light beam LB from the projector TL is cut off by the cup DC1 and the photodetector RL generates a photodetection signal. When this photodetection signal drops below a voltage E2 at time t1 and time t2, a discrimination signal is outputted from the output terminal of the level discrimination circuit AMP. A discrimination signal storage circuit SMC stores the discrimination signal applied earlier at the time t1 between two discrimination signals outputted from the level discriminating circuit AMP and also outputs a signal indicating the presence of the cup. Thus, the presence/absence state of a detected body is detected accurately all the time.

Title: Phase comparator circuit
Inventor: OKASHIN YAMATO
IPC: H03L7/085
Filed: 1983-05-25
Abstract: PURPOSE:To attain the use of a resistor with less accuracy by the constitution that no DC current flows to a resistor constituting a multiplier in a circuit comparing the phase of two signals of opposite phase with each other. CONSTITUTION:The phase of rectangular wave signals + or -S3 of opposite phase being an output of a frequency divider 3 and pilot signals + or -S5 of opposite phase with each other are compared and its output is inputted to a VCO1 via a filter 6 and an amplifier 7. A phase comparator section 4 consists of current mirror circuts 11-14, transistors (TRs) Q31-Q44 and resistors R11, R12 for multiplication in a PLL circuit constituted like this. A multiplication output voltage between the signals S3 and + or -S5, i.e., a phase comparison output voltage is obtained at the resistors R11, R12. Since the upper and lower parts of the circuit constitution in the phase comparator section are balanced in this case, no DC component flows to resistors R11 and R12. Thus, resistors with low accuracy are used. Further, since the TRs are arranged symmetrically, the circuit integration is attained easily.

IPC: H05G1/24
Filed: 1990-04-09
Abstract: PURPOSE:To remove the wave tail of a high voltage in a simple circuit by connecting a thermister circuit in reversely parallel to a high voltage rectifier, and operating the thyrister circuit immediately after the X-ray photographing to discharge the charged electric charge. CONSTITUTION:When an X-ray photographing is started, and a switch 1 is turned off, the application of DC high voltage is turned off, and the X-ray photographing is finished. In this case, a control circuit 14 operates a photothermister 11 through photocouplers 15 and photowaveguide cables 16, and an electric charge charged in a smoothing capacitor 6 and a high voltage cable electrostatic capacity to ground 10 is discharged through a discharge circuit 13. And after that, a reverse current is generated by an LC resonance circuit formed of the secondary side coil of a transformer 2, the capacitor 6, and the electrostatic capacity 10, and the thyrister 11 is bypassed reversely and extinguished forcebly. As a result, there is no fear of hurting the transformer 2 and the like, and the wave tail of the high voltage can be removed in a simple circuit.

Title: Pilot shutoff valve
Inventor: IKEMOTO HIROYUKI
IPC: F16K31/122
Filed: 1989-04-12
Abstract: PURPOSE:To avoid the sudden closing of a shutoff valve by applying the constitution wherein the degree of continuity between a pilot chamber and a pilot port gradually decreases as a valve element approaches to a valve close position. CONSTITUTION:When a difference between pressure P1 in the first pilot chamber 66 and pressure P2 in the second pilot chamber 96 is equal to or less than the spring force of a compression coil spring 62, a shutoff valve increases a degree of opening with a valve element 48 located at a valve close position and the difference exceeding the spring force, in accordance with the extent of an increase in the pressure difference. When this difference reaches the predetermined value, the degree of opening does not increase. Even when the pressure difference suddenly drops in a valve open state, the degree of continuity between the first pilot chamber 66 and the first pilot port 82 is gradually reduced as the valve element 48 approaches to a valve close position. Consequently, the shift speed of the valve element 48 is gradually reduced and sudden valve closing can be avoided. On the contrary, sudden valve opening can be also avoided even in a sudden increase in the pressure difference.
