Title: Heat treatment method for semiconductor substrate
Inventor: YOSHIDA TAKUKATSU
IPC: H01L21/26
Filed: 1988-04-27
Abstract: PURPOSE:To restrain generation of slips, etc., small so as to maintain electric uniformity under the substrate surface by accumulating a film consisting of material higher in light absorption factor than a substrate, on the surface near the outer fringe of that semiconductor substrate, and heating it by light irradiation. CONSTITUTION:For example, as a semiconductor substrate 1, a half insulating GaAs substrate is used, and a layer to which 19Si<+> is implanted is formed on the surface of one side of the substrate 1 by island-shaped pattern, and films 2 consisting of tungsten (W) are accumulated each in ring-shape on both sides near the outer fringe of the GaAs substrate 1, and further as the substrate protective film at heat treatment, silicon nitride (SiNx) films are formed on the entire face of both faces of the substrate 1 including W-film 2. Next, the substrate 1 where this W-film 2 and protective film are formed is introduced in a light irradiation heat treatment device and is irradiated and heated in the atmosphere of N2 or inactive gas from both sides of the substrate 1 with a tungsten halogen lamp for heat treatment.

Title: Double system electronic device for railroad
Inventor: HIRATA KEIJI
IPC: G06Q50/30
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To confirm normality or abnormality of a collating circuit and a computing processing device and to prevent the occurrence of malfunction of an apparatus at a site by a method wherein even when each computing data of a double system computing processing device effect malfunction and are not brought into non-coincidence with each other, coincidence of computing data is collated. SOLUTION: During inspection of a collating circuit 3, a control part 9 temporarily suspends output of data to a general purpose I/F part 6 by the collating circuit 3. Further, data of memory 13 and a memory 14 are inputted to a collating circuit 3 by a command based on a control signal 18 from the control part 9. Since the data of the memories 13 and 14 are not equal to each other, if the collating circuit 3 performs normal operation, non-coincidence of collating data is detected and a CPU 1 and a CPU 2 are reset by means of a reset signal 4. When the CPU1 and the CPU 2 are reset, it is detected that the collating circuit 3 is normally operated. This constitution confirms normality or abnormality of the collating circuit and a computing processing device.

Title: Ultrasonic switch
Inventor: UEDA MASAZUMI
IPC: G01S7/52
Filed: 1987-04-24
Abstract: PURPOSE:To prevent a detected distance from being varied due to a temperature variation, by stopping the sampling, when a noise component is superposed on a receiving signal, and fetching exactly a temperature signal. CONSTITUTION:A temperature of a sensor part 2 is detected by a temperature detecting circuit 8. An output from an ultrasonic vibrator 5 and an output of the temperature detecting circuit 8 are added by an adder 7, and sent out to an amplifying unit 1 through a detecting circuit 9. A sample holding circuit 24 of the amplifying unit 1 samples only a temperature signal from an output of the detecting circuit 9. This sample holding circuit 24 is brought to a non- operation, when a noise is detected by a comparing circuit 23. From a detecting gate generating circuit 26, a gate signal of pulse width corresponding to a temperature is outputted, and applied to a signal processing circuit 28. By the signal processing circuit 28, an object within a prescribed range is detected.

Title: Digital current differential relay
Inventor: ITO TOKUO
IPC: H02H3/28
Filed: 1988-04-27
Abstract: PURPOSE:To produce a stabilized output continuously even when an internal fault is removed previously at the counterpart end, in a relay for performing ratio characteristic operation, by leading out the result of the ratio characteristic operation through a time limit reset timer. CONSTITUTION:An output 14a from a ratio characteristic operating section 14 is ORed with an output from a time limit reset timer 21 through an OR gate 22 and employed as an output 15 of a differential relay. The timer 21 is controlled by the output from an AND gate 23 for making AND of the output 14a from the ratio characteristic operating section 14 and an output from a level detecting section 24 for detecting that the current IA at its own end is higher than a predetermined level. By such arrangement, differential relay output 15 can be produced continuously and reliably even for current inverting phenomenon occurring after tripping of a circuitbreaker at one end due to inner fault in parallel two line transmission line.

When a switch 24 is manipulated, both pilot pressure change-over valve 34 and the vibration restraining shut-off valve are changed-over into a passage opening position in a hydraulic pressure condition in which the pressure of an accumulator 12 is substantially equal to the pressure of a head side hydraulic chamber 11 in a boom cylinder 5. Further, when the switch 24 is turned on, if the pressure of the accumulator 12 is lower than the pressure of the head side hydraulic chamber 11 in the boom cylinder 5, the discharge pressure of a hydraulic pump 14 is forcibly accumulated in the accumulator 12 under action by the pilot pressure change-over valve 34, a pressure accumulating valve 15 and the like. Thus, the vibration restraining shut-off valve 18 is changed-over into the passage opening position.
