Title: Suspension type continuous heat treatment furnace
Inventor: MAKI NOBORU
IPC: F27B9/00
Filed: 1985-03-06
Abstract: PURPOSE:To shut off the inside of a suspension type continuous heat treatment furnace for heat-treating successively materials to be treated and the external air except in the inlet and outlet for the materials to be treated and to improve the thermal efficiency of said furnace by providing transfer rollers on both side surfaces of the furnace body and attaching suspension hooks for the materials to be treated on conveying bases thereon. CONSTITUTION:A suspension frame 11 is lowered from a ceiling door 2 of the heat treatment furnace 1 and the suspension hooks 6 attached with the materials 7 to be treated are held and lowered. After the hooks 6 are imposed on the conveying bases 5, 5' in the furnace, suspension rods 12 are removed from the hooks 6 and are placed on the transfer rollers 4, 4' on both sides; thereafter the frame 11 is pulled up and the door 2 is closed. While the hooks 6 attached with the materials 7 are transferred on the rollers 4, 4', the materials are subjected to heat treatment in the furnace and are transferred onto reset rollers 9, 9', then a ceiling door 14 in an ejection port is opened and the materials are taken out of the furnace by the frame 11. The furnace inside is shut off from the external air except in the inlet and ejection port for the materials 7. Since the inlet and ejection port are held closed as well except when needed, the intrusion of the external air into the furnace and consequent decrease of the furnace temp. are obviated and the operation with high thermal efficiency is made possible.

Abstract: PURPOSE:To perform a time-out for no sheet in a host system and to prevent data from being fed again by providing a sheet feeder capable of stocking predetermined number of sheets, means for counting the number of sheets at each time of printing, and means for displaying residual number of the sheets. CONSTITUTION:When 200 sheets are, for example, inserted into a sheet feeder 71 and a sheet feeder lever 72 is returned to its original position, a CPU 68 in a controller 50 initializes a counter 200 for storing residual sheet information of the sheets set in a RAM 61 by the return of the lever 72. Thereafter, each time when a print command is sent from the CPU 68 to a printer engine 51 through an engine interface 65 to send a print command to print, the CPU 68 counts down a counter for storing residual sheet information in the RAM 61, and repeats until the residual sheets become 10. The number of the residual sheets at this time is displayed on a counter 81 of an operation panel 52 through a panel interface 66 under the control of the CPU 68. When the residual sheets become 10, an alarm lamp 82 of the panel 52 is flashed to inform a sheet supplying period.

Title: Field-effect transistor
Inventor: IWATA HIROSHI
IPC: H01L29/78
Filed: 1990-02-26
Abstract: PURPOSE:To make a semiconductor element itself to have a gettering effect by interposing a thin film layer mainly composed of an oxide of tungsten, molybdenum or vanadium between a gate insulating film and a gate electrode. CONSTITUTION:A negative bias is given between a gate electrode 9 and a drain electrode 12 to perform driving. Assuming the gate side is negative, metal atoms such as sodium Na existing in a gate insulated film 6 react to an oxide of a thin film layer 8 to be gettered. For instance, when an oxide WO3 of tungsten is used as the thin film layer 8, prescribed reaction is generated so that Na<+> ions having existed in the gate insulating film 6 are gettered in the thin film layer 8 and passivated stably. This reaction is held so long as the polarity of impressed voltage is reversed and Na<+> ions gettered in the thin film layer 8 consisting of WO3 do not return to the gate insulated film 6 and thereby a transistor having stable operating voltage can be obtained.

Abstract: PURPOSE: To prevent transmission/receiving switching dependent upon howling and external noise by using a vibration pickup-type microphone and air conduction- type speaker and by causing the output of the microphone to pass through a BPF to drive a voice start controller and by switching transmission and receiving.  
     CONSTITUTION: When the user who wears vibration pickup-type ear-microphone 1, which picks up a bone conduction voice signal to convert it to an electric signal, and air conduction-type speaker 2 does not speak, switch SW 1  of the receiving system is conductive, and receiving voice is heard from speaker 2 through receiver 7 and amplifier 8. When the user speaks, microphone 1 picks up the bone conduction voice signal (vibration) and amplifies the output in 3 and causes it to pass through BPF 4 to drive voice start controller 5, and switch SW 2  of the transmission system and switch SW 1  are made conductive and nonconductive respectively. Consequetly, the output of microphone 1 is input to oscillator 6 and is transmitted to the external. Since the output of the mike is caused to pass through the BPF, the absolute value of crosstalk is reduced to prevent howling, so that operations of switches dependent upon external noise can be prevented.

Then, a p-InGaAsP wavelength layer 21, a first n-InP current-blocking layer and a second n-InP current-blocking layer 12, 13 are grown in succession on the substrate 11. Then, a stripe groove 22 along a <001> direction is formed, by using an etching solution such as hydro-chloric acid, on a wafer whose first crystal growth has been completed. Then, a first p-InP clad layer 14, an InGaAsP active layer 15, a second n-InP clad layer 16 and an n-InGaAsP contact layer 17 are grown in succession on the current-blocking layer 13. During this process, a thickness of the first p-InP clad layer 14 is grown to be thin so that the light conducted through the InGaAsP active layer can be conducted simultaneously through the p-InGaAsP waveguide layer 21. Lastly, an n-side electrode 19 is formed on the side of the n-InGaAsP contact layer 17 and a p-side electrode 18 is formed on the p-InP substrate 11; a chip is separated.

Title: Non-directional antenna shaped for polarized wave
Inventor: YAMAWAKI SEIICHI
IPC: H01Q21/24
Filed: 1989-02-27
Abstract: PURPOSE:To make the size of an antenna small by forming the antenna by using four pieces of 3dB 90 degree hybrid circuits each of which has an input/ output terminal and two pieces of output terminals and four pieces of monopole radiant elements each of which is connected to said output terminal. CONSTITUTION:A transmission signal supplied from the input/output terminal 1 is supplied to the monopole radiant elements 11 to 14 through a hybrid circuit and a 90 deg.-phase shifter, and a clockwise-rotational circularly polarized wave is radiated from the mopnopole radiant elements 11 to 14. Similarly, as for the transmission signal to be supplied from the input/output terminal 2, the signal phase of a feeding point D1 based on the signal of the feeding point D4 is delayed by 270 degrees behind the signal of the feeding point D4, and all the transmission signals of the feeding points D1 to D4 become equal. Accordingly, it can be radiated as a counter-clockwise-rotational circularly polarized wave from the monopole radiant elements 11 to 14. Consequently, the clockwise- rotational and the counter-clockwise-rotational circularly polarized waves can be transmitted simultaneously from the input/output terminals 1 and 2 respectively.
