Title: Multiplexed video phone system
Inventor: SUGA MITSUHIRO
IPC: H04M9/00
Filed: 1988-06-16
Abstract: PURPOSE:To adjust the peaking quantity of the title system to the optimum by providing slave interphone equipment provided with a video signal modulator circuit and peaking circuit and master interphone equipment provided with a level detection circuit and level discrimination circuit and connected them with each other with a two-wire cable. CONSTITUTION:In the course of the adjustment of the peaking quantity of this multiplex TV-phone system, the video signal of a TV camera 22 is not inputted to a video FM modulator 25 when the switch 37 of slave interphone equipment 2 is opened, but signals of a carrier oscillating frequency are outputted to a peaking circuit 36. The circuit 36 performs peaking on its input signal and the output of the circuit 36 is inputted to master interphone equipment 1, where the signal level is detected by means of an envelope detector 17, through a two-wire cable 3, etc., When the carrier oscillating frequency is changed and a new signal level is detected accordingly thereafter, a wind comparator 20 discriminates whether or not the newly detected signal level is within a prescribed range by using the previously detected signal level as a reference and informs of a discriminated result. Therefore, the circuit 36 can be adjusted so that the signal level can be within the prescribed range and the peaking quantity can be adjusted to the optimum.

Abstract: PURPOSE: To form an integral single layer polymeric microporous filter membrane by passing a reinforcing web coated with a polymer through a quenching bath contg. a non-solvent of the polymer for a time sufficient for generating the micropores through the inside of the coating. CONSTITUTION: The reinforcing web 10 is supplied between calendering rollers 12 and 14. This web 10 is coated with a casting soln. in a liquid storage tank 16.

Title: Voltage stabilized circuit
Inventor: TAKEMAE YOSHIHIRO
IPC: G05F1/10
Filed: 1977-12-12
Abstract: PURPOSE: To reduce the effect of noise from one load circuit to another load circuit by inserting noise limiters between a reference voltage generator circuit and the load circuits, respectively.  
     CONSTITUTION: Reference voltage is supplied to a number of load circuits from a common reference voltage generator circuit 1. Noise limiters 4A to 4C to use transistors as high resistors are inserted between the reference voltage generator circuit 1 and the load circuits 2A to 2C. For example, when this permits the load circuit 2A to operate and noise to be generated, the load circuit 2B operates before the noise goes off. This permits this noise to be applied to the load circuit 2B operates before the noise goes off. This permits this noise to be applied to the load circuit 2B by the circuit shown in the arrow and to pass through the two-stage noise limiters 4A and 4B. As a result, considerable noise can be controlled before it reaches the load circuit 2B.

Title: Complementary type field-effect metal-insulator- semiconductor device
Inventor: SAKURAI JIYUNJI
IPC: H01L29/78
Filed: 1978-12-01
Abstract: PURPOSE:To raise a latch-up dielectric strength, by separating a p-channel and an n-channel field-effect transistors from each other by an insulating layer and coating the bottoms of the transistors with an n<+>-layer and a p<+>-layer. CONSTITUTION:A p<+>-well is provided in an n<+>-silicon substrate 1'. When no- additive silicon is epitaxially grown, an n<->-layer 4 and a p<->-layer 5 are produced by self-diffusion. A nitride film is used as a mask to produce an oxide layer 3 which extends to the substrate 1'. A p-channel and an n-channel field-effect transistor are produced in the exposed layers 4, 5 by a conventional method. As a result, a p- channel and an n-channel metal-insulator-semiconductor field-effect transistors are separated from each other by the layer 3 and the bottoms of the transistors are coated with an n<+>-layer are a p<+>-layer respectively. A latch-up dielectric strength of a pnpn-construction is thus raised. Although the p<+>-well 2' has a large depth and a high concentration, it does not constitute the substrate part of a field-effect transistor manufacturing region. Therefore, the p<+>-well 2' does not hinder dense integration and speeding-up.

Title: Production of liquid crystal alignment layer and liquid crystal alignment layer
Inventor: EGUCHI TOSHIMASA
IPC: B29L11/00
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal alignment layer with which a liquid crystal display element can be efficiently produced in high yield by applying and forming a film of a liquid crystal aligning agent on a plastic film, and stretching for alignment treatment. SOLUTION: First, a liquid crystal aligning agent is applied and baked on a plastic film and then stretched. Thus, a liquid crystal alignment layer which is subjected to orientation treatment can be obtd. before the film is applied on a substrate having transparent electrodes. By using this liquid crystal alignment layer, a liquid crystal alignment layer can be formed in a short process of transferring the film to a transparent electrode substrate. Therefore, a liquid crystal display element can be efficiently produced in high yield. The plastic film used is preferably a polyester, polycarbonate or polyamide film, but not limited to these. When the orienting film is to be used, the film is transferred to a substrate having transparent electrodes, and therefore, the plastic film is preferably subjected to release treatment.
