Abstract: PROBLEM TO BE SOLVED: To prevent a backward flow of each gas from being generated from gas feeding lines of a higher flow rate into gas feeding lines of a lower flow rate by a method wherein the gas of the lowest flow rate among a plurality of the gases is fed through the gas feeding line provided at the longest distance from a gas outlet part. SOLUTION: In the feed A of mixed gas, the first gas G1 by the lowest flow rate is fed to a gas feeding line L1 separated by the longest distance from a gas outlet part G0 and the n<th> gas Gn of the highest flow rate is fed to a gas feeding line L which is closest to the part G0 . Moreover, the third gas G3 which is fed to a gas feeding line L3 adjacent to the line Ln , which is fed the n<th> gas Gn , is gas of a flow rate lower than that of the n gas G and the second gas G2 . which is fed to a gas feeding line L2 adjacent to the L3 , which is fed the third gas G3 , is gas of a flow rate lower than that of the gas G3 . Thereby, it can be made to nil that the gases of the higher flow rate flow backward or are diffused in the gas of the lowest flow rate.

Title: Sample holding circuit
Inventor: SUZUKI TOMOHIKO
IPC: G11C27/02
Filed: 1982-01-13
Abstract: PURPOSE:To eliminate the limitation of the maximum frequency of an input signal due to a low transition frequency of a pnp transistor, by avoiding flowing a current obtained by a change of the input signal voltage to the pnp transistor. CONSTITUTION:Transistors TR21 and 22 are turned on and off respectively if TR28 and 29 are on and off respectively and the input voltage has a higher level than the output voltage. Then a current flowing through the 2nd constant current source 30 is supplied through the TR21 from a current source VCC, and the current of the 1st constant current source 25 charges a capacitor 23 via a TR24 having a diode connection and forms a charging path of an ON state. While the TR24 is adversely biased by an emitter follower 27, a TR26, etc. when the output voltage increases. Thus the TR24 is turned off, and the capacitor 23 is discharged. Such TR21, 22, 24 and 26 to which the current flows in response to the change of the input voltage are turned into an npn type respectively. As a result, the limitation with which the maximum frequency of an input signal is lowered is eliminated with a high transition frequency.

Title: Output stage of ac voltage switch
Inventor: DEIITAA KURITSUTSU
IPC: H03K17/082
Filed: 1990-01-12
Abstract: PURPOSE: To make a switching converter with respect to temperature stable by providing a MOS-FET and making a FET or a transistor(TR) of a source or emitter follower conductive with a control stage when a rectifier is conductive. CONSTITUTION: An oscillator 1 of an AC voltage proximity switch keeps oscillation so long as no magnetized object is in existence in the vicinity of a coil of an oscillation circuit 2 and a rectifier 4 is in an open state. When the magnetized object approaches the coil of the oscillation circuit 2, the oscillator 1 stops the oscillation and its output makes a TR 1 conductive to control a TR 2. Then a control stage 3 triggers a MOS-FET 3 to make the rectifier 4 conductive and in the case that a load 5 is a relay, switching is started and the MOS-FET 3 generates a required stabilizing low voltage of about 2V.

Abstract: PURPOSE:To reduce the coloring of a reflected light by growing an absorptive film at one part of the selective transmitting film consisting of a high-refractive- index film and a low-refractive-index film overlaid on a front lens. CONSTITUTION:The inside of a front lens 2 is coated with a selective transmitting film 4 where a absorptive film 5 is grown. The selective transmitting film 4 is made by growing a Cu film 5, as an absorptive film, on the inner face of the front lens 2, and growing TiO2 films 6 as high-refractive-index films and SiO2 films 7 as low-refractive-index films alternately on this film 5, and lastly, growing an TiO2 film 6. For the spectral transmisstivity properties of the selective transmitting film 4, it has the transmissivity of 50% or more in the wavelength range of 470-550nm where a light for a vehicle works as a fog clamp. Accordingly, the transmitted light is emitted as an yellow light at the lighting of a tungsten bulb.

Abstract: PURPOSE:To prevent mis-reception by eliminating the effect of an offset and obtaining power of a signal subjected to frequency discrimination. CONSTITUTION:An input signal 10 is inputted to a DF1, in which a signal of a specific frequency is discriminated.

Abstract: PURPOSE:To prevent the generation of incompletely recorded area in a tape by using a tape sag absorbing arm to absorb instantaneously the tape sag. CONSTITUTION:When a sag is produced to a tape 2' by sudden vibration, a sag absorbing arm 20 is turned instantaneously clockwise by a spring 22 and put deeply between a post 10' and a post 9.

Thus a head touches a head drum 14 with the tension needed for vido recording at an inlet part C of the tape 2'. In such a way a defective touch between the tape and the head is prevented an the disturbance of pictures due to the vibration at a practical level is eliminated.

Title: Solid image pickup unit
Inventor: WADA TAKAMICHI
IPC: H04N5/335
Filed: 1978-01-19
Abstract: PURPOSE: To improve the sensitivity for blue light by sensing light by the surface of the Si substrate under a transparent electrode in a solid image pickup unit.  
     CONSTITUTION: When voltage VG is applied to the gate of MOS transistor 9 in pulses, a depletion layer is formed on the surface of Si substrate under transparent electrode 4 becuase poly-Si gate 8 is connected to drain diffusion layer 7. Carrier is accumulated in the depletion layer by the light irradiated through transparent electrode 4. Since this carrier is flowed to source diffusion layer 6 and the potential of layer 6 is lowered, charge from drain diffusion layer 7 is flowed. Then, since the potential of layer 7 is lowered, the potential of transparnt electrode 4 is lowered to exhaust the carrier of the depletion layer. On a basis of the operation above, optical signals are accumulated as potential change components of drain diffusion layer 7, and signals can be taken out to the external by applying the voltage to gate 11 in pulses.

Abstract: PURPOSE:To prevent flow of melted conductive particles and insulating adhesive between conductive parts and concentration of them at the end of an element by increasing coating area of anisotropic conductive adhesive larger than the press-bonding area of a film to a board when the film is press-bonded to the board by using the conductive adhesive having the conductive particles and the insulating adhesive. CONSTITUTION:A board 13 is press-bonded to a film 14 to be connected by using an anisotropic conductive adhesive 12 made by mixing conductive particles 11 in insulating adhesive 10. In this case, the coating area 16 of the adhesive 12 is increased larger than a press-bonding area 17. Thus, since the adhesive 12 is melted on a press-bonded part 18 while both the adhesive 10 and the particles 11 are not melted on a non-press-bonded part 19, conductive parts 15 are blocked even when it is press-bonded. Thus, a conventional capillary tube phenomenon does not occur.

An arithmetic device 7 inspects the perpendicularity of the surface to the optical axis of the camera 1 by counting the number of grid lines contained in each grid picture in a prescribed direction and comparing the count number in each other with those of the other areas.
