Title: Screening method for semiconductor element
Inventor: YUASA HIROKAZU
IPC: H01L21/326
Filed: 1981-04-03
Abstract: PURPOSE:To make a semiconductor element with latent defect in an insulation layer perform screening in the state of wafer, by applying voltage sufficient enough to cause dielectric breakdown between a wafer and an upper electrode. CONSTITUTION:A wafer 21 is mounted on a lower electrode 29 of copper plate. A polyimide film as an insulator is inserted between lower and upper 30 electrodes of copper plate, where AC voltage is applied. A semiconductor substrate 22 of the wafer 21 consists of silicon, the 1st, 2nd-3rd insulation layers 23, 25, 27 of silicon oxide, the 1st wiring layer 24 of polycrystal silicon, and the 2st wiring layer 26 of aluminum. When the voltage is intense enough to make each of inulation layers 23, 25, 27 cuase dielectric breakdown due to latent defect, the dielectric breakdown current will flow instantly at the defective portion. Hence, a defective silicon oxide layer without normal dielectric breakdown strength can be screened easily.

Title: Premixture combustion device
Inventor: SATO MINORU
IPC: F23N5/24
Filed: 1988-03-03
Abstract: PURPOSE:To prevent the generation of carbon monoxide and a smell due to gasifying pulsation during low combustion, by a method wherein an ion current detecting means and a signal waveform recognizing means are mounted to a combustion device to premixe gasified gas of liquid fuel, e.g. kerosene oil, and air. CONSTITUTION:A waveform recognizing device 14 has function to compute a time average value I0 and a fluctuation width  I, detected by an ion electrode 11, and calculate  I/I0 to compare the result with a reference value, and controls a drive device 13 of a pump 3. When a combustion amount is decreased, since the average time I0 is decreased and simultaneously the fluctuation width  I is increased, when a ratio  I/I0 between the average value and the fluctuation width is calculated, the value indicates a further higher change. Even when a combustion amount is reduced to a value lower than a specified value due to choking of a blower with refuse,  I/I0 is calculated by the control circuit 14. When the result exceeds a given value, combustion is stopped and a large amount of CO can be prevented from discharge.

Title: Heart valve prosthetic device
Inventor: TOOMASU EI SHIRUBESUTORINI
IPC: A61F2/24
Filed: 1989-03-02
Abstract: PURPOSE: To satisfy many requirements about a membrane for a cardiac valve by using a fabric obtained by arranging three sets of approximately parallel lines at a certain angle and weaving each other in such a way as to prevent one weaving thread from sliding along the other weaving thread as a cardiac valve membrane. CONSTITUTION: A weaving thread (x) is woven into under a weaving thread (z) across a weaving thread (y). The weaving thread (y) is woven into under a weaving thread (x) across a weaving thread (z). The weaving thread (z) is woven into under a weaving thread (y) across a weaving thread (x). A spacer member 16 of a stent 14 is folded to make a cardiac valve membrane in such a form that one set of parallel threads is oriented to an approximately circumferential direction of an artificial prosthetic device and that other two sets of threads are orientated to an angle of about 90 deg. to all flanges of the heart valve member 16 in its radial direction (r). By doing such orientation, there is obtained a cardiac valve which can be extended more in the radial direction than in the circumferential direction.  Since the fabric can be bended easily in a proceeding direction, the valve can be opened easily by bending the membrane even if a pressure drop via the valve is low.

Title: Data communicating system for token bus system
Inventor: TANIGUCHI KYOJI
IPC: H04L12/40
Filed: 1990-03-01
Abstract: PURPOSE:To eliminate a need of station(ST) information change and reception confirmation data transmission at the time of restoration by reading ST state data (DS) to transmit it to normal STs and rewriting pertinent data of ST DS with trouble data at the time of the occurrence of trouble and rewriting it with normalcy data at the time of restoration. CONSTITUTION:A token(TK) 1 is sent to STs 101 to 10n on a bus 4 in order, and a TK identifier 11, ST number data 12, and ST DS 13 expressing the normal/trouble state of each ST with '1'/'0' respectively are registered in the TK 1. Each ST receives the TK 1 to get the transmission right and transmits data to a desired ST and detects the state of the next ST by ST DS 13 of the TK 1 at the time of the end or the stop of transmission and transmits the TK 1 in the case of '1' but detects the next to transmit the TK 1 in the case of '0'. If a transmission destination ST is monitored and is judged to be faulty, pertinent bit data of ST DS13 of the TK 1 is rewritten with '0', and restoration is inquired of the faulty ST: and when return of reception confirmation data is received, the pertinent bit of ST DS 13 is rewritten with '1' at the time of receiving the next TK 1, and the TK 1 is transmitted to the restored ST. Thus, procedures of information change and reception confirmation are omitted to perform efficient communication.

Water is discharged from the spray orifice 174 of the spray pipe 170 at an acute angle, and uniform spraying is conducted to the overall width of a compression path. Accordingly, water or another lubricant can be sprayed equally onto an asphalt surface even on a slope.
