Title: Method for reading signal of solid-state device
Inventor: AKIYAMA TOSHIYUKI
IPC: H04N5/335
Filed: 1983-03-18
Abstract: PURPOSE:To obtain a video signal in which a low frequency noise component is decreased by setting a width tau of a pulse of pulse train of an output signal to nearly a half of a reset pulse period T and extracting a video signal from the fundamental wave component of the said pulse train by means of synchronous detection. CONSTITUTION:When an amplitude V0(1) of an output signal pulse in Fig. C is changed by a signal charge quantity of Qs(1)=kcos(Pt1), where t1=nXt, the output signal pulse train is expressed in Equation I . In order to prevent mixture of low frequency noise such as 1/f noise, a high frequency region, especially the basic component corresponding to the 3rd term m=1 in Equation I is extracted by a BPF, and a base band component (1st term in Equation II) of a signal (Equation II) as the result of multiplication between the fundamental component and a local signal cosomegaRt is extracted by an LPF, the frequency characteristic is corrected so as to obtain a video signal kcosPt where the low frequency noise such as 1/f noise is less. The amplitude of the detecting signal depends on the pulse width of the output signal in Fig. C. The level of the detecting signal at P-O deciding the SN ratio to the low frequency noise especially is changed in proportion to ¦(sinomegaRtau/2)/omegaR¦. Thus, in setting the hold time of the output signal to tau-T/2, the video signal having the best SN ratio is obtained.

Title: Screening system of integrated circuit
Inventor: NAGASAWA SHIGENOBU
IPC: H01L21/66
Filed: 1984-03-08
Abstract: PURPOSE:To prevent damages to other integrated circuits and a screening device when an abnormal value is detected in an integrated circuit tested, by opening a switch connected to the integrated circuit which has generated the abnormal value. CONSTITUTION:A matrix element Mij and current monitors S1-S7 are carried on a screening substrate 5. Applying a predetermined voltage, the values of the current monitors S1-S7 are read by a CPU7 in a predetermined cycle. The values thus obtained are compared with the values obtained in the last reading operation and stored in a memory unit 7. These operations are repeated. When latch-up occurs in an IC in a part of the matrix element M13, the current values observed at the current monitors S3, S5 are changed. The CPU7 drives a relay R13 through a driving circuit 9 to open a switch SW13, whereby the current path of the IC is cut off for preventing burnout thereof and thus damages to the other IC's and the screening device are prevented.

Title: Controller for combustion type warm air heater
Inventor: MORI KEIICHI
IPC: F24H3/04
Filed: 1986-02-28
Abstract: PURPOSE:To prevent the occurrence of a hazard, e.g., a toxication trouble, owing to CO, by a method wherein the ventilation rate of a room is computed according to gradient of a room temperature, from a computing result, the cycle of a timer is decided, and ventilation of the interior of a room is reported at every cycle of a timer. CONSTITUTION:When heating is effected by means of a specified combustion amount, a room temperature is increased, a detecting timer 25 is actuated at a time Ta, and combustion of a burner 13 is stopped during a time between times Ta and T. As a result, a room temperature is decreased by DELTAt. The DELTAt is detected by an gradient detecting part 26, and room environment is estimated by a computing part 27. A ventilation timer part 28 sets a timer time to a low value when the temperature change DELTAt is low and sets to a high value when the DELTAt is high. When decided timer time combustion is continued, a reporting part 29 reports ventilation. A safe timer part 31 is operated simultaneously with a reporting output from the reporting part 29. When ventilation is not effected until a timer is completed, a safety shut off part 32 is operated. If no ventilation is made until timer is completed, a safety shut off part 32 is operated when a safety valve 10 is closed to stop combustion. When, before completion of a safety timer 31, it is decided that ventilation is made, no safety shut off part is operated, combustion is continued, and a ventilation timer part 28 starts counting again.

Title: Gas evacuating method for solar heat collector
Inventor: YOKOTA TAKAHARU
IPC: F24S10/70
Filed: 1982-03-23
Abstract: PURPOSE:To provide a high vacuum gas evacuating method for evacuating gases from an outer glass casing of a solar heat collector in which the baking temperature of a copper pipe section is made somewhat higher than a glass section without deforming the outer glass casing. CONSTITUTION:A sheath heater 3 is inserted in the copper pipe 8 as a heat pipe from the open end of the latter to thereby heat the pipe and at the same time, a vacuum pump 5 is connected to the open end to evacuate the interior of the pipe at high vacuum or to cause an inert gas to flow into the pipe from the open end so that the gases in the glass outer casing as evacuated. Thus, by so doing, the copper pipe which is far less deformed than glass even at high temperatures can be subjected to a high temperature baking process in its own way and the glass outer casing can be evacuated for a short time to a reliably high vacuum without lowering the vacuum degree after evacuation. At the same time, the surface of the heat pipe becomes extremely clean and a favorable heat transfer efficiency can be obtained.
