Title: Lateral type diode
Inventor: MURATA EIJI
IPC: H01L29/866
Filed: 1981-12-16
Abstract: PURPOSE:To obtain the inexpensive lateral type diode whose carrier concentration is not required to be controlled accurately, by using diode pairs constituted by p-n junctions which are biased in the forward direction, connecting the diode pairs in parallel so that their polarities are different one another, thereby constituting the diodes having the bidirectional polarities. CONSTITUTION:In a semi-insulating GaAs substrate 1, p type regions 12 or 22 and n type regions 13 or 23, each comprising five regions, are alternately arranged in the neighboring positions so that the reverse conductive regions are placed between the same conductive regions. A first diode group 14 or a second diode group 24 is formed in an island shape, respectively. One end and other end of each of both diode groups, which are selected so that their polarities are opposite to each other, are connected in parallel by ohmic electrodes 5 or 6. When a voltage is applied to the electrodes 5 and 6 under this state, junctions 17 and 27 are biased in the reverse directions. The junctions 17 and 27 are shorted by ohmic electrodes 18 and 28. Even though the carrier concentrations in the p type region at and the n type region are varied for a broad range, approximately constant withstand voltage can be obtained.

Abstract: PURPOSE:To control an AC power supply applied between a first electrode and a second electrode by gate voltage by forming two MIS type transistors having a common source region, connecting a drain region in one transistor to the first electrode and connecting a drain region in the other transistor to the second electrode. CONSTITUTION:When a first electrode 1 is kept at high potential and a second electrode 2 at low potential, interruption or conduction can be controlled by a gate electrode 11 in a MIS type transistor 3, a MIS type transistor 4 is brought to the state similar to the forward characteristics of a P-N junction, and the resistance of the transistor 4 slightly changes by gate voltage but the transistor 4 is brought to a conductive state, thus controlling currents flowing between the first electrode and the second electrode by gate voltage. When the electrode 1 is kept at low potential and the electrode 2 at high potential, on the contrary, the relationship of the MIS type transistors 3 and 4 is only reversed, thus controlling an AC power supply by gate voltage when using a MIS type transistor cell.

Title: Analog delay line
Inventor: ENOMOTO TADAYOSHI
IPC: H03H19/00
Filed: 1981-12-16
Abstract: PURPOSE:To form a multistage delay line and a tapped multistage delay line, by connecting an arbitrary number of delay lines consisting of a switched capacitor (SC) circuit and an integration circuit in cascade. CONSTITUTION:An SC circuit 30 consisting of a switch and a capacitor stores analog signals temporarily. Switches 32-35 consist of MOSFETs. An integration circuit 50 comprising an operational amplifier 51, a capacitor 52 and a switch 53 outputs a signal when a signal charge of a capacitor 31 is transferred to the capacitor 52. In applying a pulse phi1 to a terminal 41, the capacitor 31 is charged, and when the pulse phi1 is disappeared, the charge is stored. Since a pulse phi2 is set on or off to a terminal 57, the integration circuit 50 is reset and the potential at a terminal 56 is zeroed. In setting a pulse phi3 to a terminal 42, a signal charge in the capacitor 31 is transferred to the capacitor 52 and an output delayed than an input signal by one period appears at the terminal 56. Signals inputted at each period are outputted with delay by one period each.

Filed: 1987-08-14
Abstract: PURPOSE: To obtain clear-cut image over the whole frame even with illumination using a compact single light source by providing corrective measures against uneven recording produced between the central portion and the periphery of the copy caused by reduction of illumination intensity with a single light source at periphery of recording plane for image of a black board or the like. CONSTITUTION: Emitted light from a halogen lamp 10 is focused in slit shape through condenser lens 13 and a 1st cylindrical lens 14, reflected by a fixed mirror 15, trimmed into slit-shaped parallel beam by a 2nd cylindrical lens 16 and directed toward a scanning mirror 17. Then this reflected beam varies its transmitting position from the left to right of an ND filter 19 in response to rotation of the scanning mirror 17, and the light becomes brighter as it goes closer to right and left ends of a black board surface because transmittance of the ND filter 19 becomes higher as approaching its both ends. However, brightness of illuminating light on the black board surface becomes nearly even because distance between the electronic copier and the black board surface is short in the central portion and becomes longer as approaching its both ends.

Filed: 1981-12-15
Abstract: PURPOSE:To improve the work efficiency of a captioned device by using a one body part to be bent and overlapped for a thin-plate-formed member constructing a silencing chamber for disusing the positioning work at the overlapped part. CONSTITUTION:In a thin-plate-formed member 5, a joining part 19 is processed to be bent, and joined with a bent fitting part 20 by calking or projection welding. In a muffler device of a closed compressor manufactured by this process, an exhaust muffler 1 is free from the slippage in positioning the bent fitting part 20, since the bent fitting part 20 is joined by calking or projection welding at the same time when the thin-plate-formed member 5 is processed to be bent at the joining part 19. This construction permits to disuse the work of positioning, improve the work efficiency, and simplify the automization.
