Abstract: PURPOSE:To lower a noise factor, and to increase Schottky reverse with-standing voltage by forming opening sections to each region for a gate, a source and a drain, removing a material for a gate electrode on respective region for the source and the drain and shaping ohmic electrodes to the opening sections in each source-drain region on a substrate. CONSTITUTION:A photo-resist film 2 is applied to a substrate, and opening sections 2s, 2d, 2g are each formed to the photo-resist film in a source region, a drain region and a gate region. An SiO2 film 1 is etched in an anisotropic manner by using reactive ion etching (RIE) while employing the photo-resist film 2 as a mask, etching openings vertical to the substrate are bored, and the photo-resist film is removed. A substance film such as a tungsten nitride (WN) film 3 is shaped in a sputtering manner as a material for a gate electrode. Ions are implanted toward the direction of the gate electrode from the source side and the drain side, and the film 1 is etched. A platinum/gold germanium (Pt/AuGe) film 4 is evaporated as a material for an ohmic electrode, and alloyed and treated, and the SiO2 film is removed, thus forming a FET.

Title: Tape guide
Inventor: SHIRAI MAMORU
IPC: G11B15/60
Filed: 1985-09-30
Abstract: PURPOSE:To keep always high guide accuracy while the increase in the tension of a magnetic tape and the occurrence of damage are prevented by constituting the tape guide while being split into a stator cylinder and a rotor cylinder. CONSTITUTION:The magnetic tape 11 is guided surely for both direction and position by an upper stator cylinder 4 and the height is restricted by a flange 5 at the stator cylinder 4. Since no gap exists between the stator cylinder 4 and the flange 5, the damage due to the protrusion of the magnetic tape 11 is not caused. On the other hand, since the lower part is the rotary cylinder 8, the friction force to the magnetic tape is small and even if an increased tension is caused in the upper stator cylinder 4 due to friction, the tension rise as the entire magnetic tape 11 is not so much large. The increase in the entire tape tension is reduced with a large winding angle while the stator cylinder 4 guides the magnetic tape 11 accurately, and the protrusion of the magnetic tape 11 between the stator cylinder 4 and the height restricting flange 5 is prevented.

Abstract: PURPOSE:To vary delay time according to the feed speed of a tape and to correct the delay time automatically by delaying a video signal of one channel by a period determined by the tape feed speed and storing the delayed signal, and reproducing the other video signal with the same delay time as said delay time. CONSTITUTION:The FM modulator 2 of a recording system R FM modulates a luminance signal from a terminal 1 and a mixer 3 mixes the FM-modulated signal with a converted color signal from a low-frequency converted color signal generator 4; and the mixed signal is separated into the 1st and the 2nd channels and one signal is recorded while delayed through a CCD delay element 6 by the period determined by the feed speed. The other is recorded as it is through an LPF8. The output of one head CH1 of a reproduction system P is applied to a switching circuit 18 through an LPF13. The output of the other head CH2 is applied through an LPF15 to a CCD delay element 16 and delayed by as long time as it was delayed through the element 6 to apply to the circuit 18 through an LPF17. Then the delay time is varied by delay time selection switches 11 and 19 according to the feed speed of the tape to correct the delay time automatically.

Title: Equipment for conveying and processing paper sheet or the like
Inventor: ABE MASAHIRO
IPC: B65H15/00
Filed: 1982-12-09
Abstract: PURPOSE:To securely pinch a sheet of paper and invert it in a sheet conveying and processing equipment with an invert-conveying function, by turning backward conveying belts at a speed equal to the circumferential velocity of a rotary member or the speed of a second conveying passage, when the sheet of paper is present in the equipment. CONSTITUTION:Paper money from a first conveying passage 1 passes through a forward conveying passage 4 and comes into contact with a stopper 7 so that the rear edge of the money is moved rightward. When the paper money is pinched in between a large- diameter rotary member 6A and a belt 5A, the member and the belt are turned at the same speed so that the money is pinched in between belts 2A, 2B and enters into a backward conveying passage 5. The speed of the belt 5A is equalized to that of the belt 2A as the paper money remains between them. At that time, the large-diameter rotary member 6A performs a slipping rotation. The next paper money is introduced through the forward conveying passage 4, inverted and moved through a second conveying passage 2 so that these sheets of money are conveyed as the front edge of the succeeding paper money is overlapped with the rear edge of the preceding paper money. As a result, these sheets of money are stacked in a storage section 23. The sheets of paper or the like are thus securely inverted and conveyed.

Title: Separation feeding device for sheet material
Inventor: KINOSHITA TSUTOMU
IPC: G03G15/00
Filed: 1989-08-22
Abstract: PURPOSE:To make it difficult for sheet material stored in a storing case to stick each other, thus making it easy to take out sheet by sheet, and install the storing case in a limited installation space by arranging the storing case in a vertical direction on an upstream side of a sheet transfer means. CONSTITUTION:A storing case 3 is arranged in a vertical direction on an upstream side of a sheet transfer means 5. This makes it difficult for sheet material 1 stored in the storing case 3 to stick each other, thus making it easy to take them out sheet by sheet. On top of that, when setting the storing case 3 on a device, the device can be installed in a limited installation space without causing any projection of the storing case 3 outward of the main body of the device. Furthermore, a suck operation port 6 of the storing case 3 is formed long vertically, and a suck operation gear 4 is installed in a way capable of elevating along the such operation port 6. Adopting such a constitution, a sheet material 1 can be separated and taken out sheet by sheet from a bunch stored in the storing case 3 by simply moving the such operation gear 4 sucking the sheet material 1 upward along the adsorption operation port 6.

Filed: 1986-09-17
Abstract: PURPOSE:To improve the insulation reliability by providing a preheater in the cooling circulation system, thereby effectively preventing the dielectric breakdown by the coolant at the restarting time after a long-time halt. CONSTITUTION:The cooling circulation system comprises a cooling duct 6, a pump 7 for circulating a coolant, a condenser 8 for cooling the coolant having an elevated temperature and a cooling water pipe 9, a coolant tank 10 for storing the liquefied coolant, a liquid-conducting pipe 11 for connecting the cooling circulation system outside the tank 13 and the cooling duct 6, and an insulation pipe 12, and a coolant such as flon R-113 or Fluorinert FC75 is adapted to circulate within this cooling circulation system. And, since, if a foil-wound transformer is restarted after a long-time halt, excitation can be performed after previously increasing the temperature of the coolant by means of a preheater 20, that is, the transformer can be excited with the temperature of the coolant having been increased, the dielectric breakdown can effectively be prevented, which had a high probability of being caused due to a low temperature of the coolant in the past.
