Inventor: SENSUI KIYOSHI
IPC: G06F11/30
Filed: 1988-10-11
Abstract: PURPOSE:To surely disconnect the power supply to an apparatus which operates under the control of a CPU 1 when abnormality occurs in the CPU 1 differentiated with an operating signal indicating the normal run of a program by differentiation circuit, and detecting appearance and disappearance of a differential signal by monitoring the differential signal. CONSTITUTION:A drive circuit 5 receives a differential signal 4 differentiated with an operating signal 2 indicating the normal run of a program by a differentiation circuit 3 and supplies a power supply voltage received from a power supply input 7 by using a power supply switch 6, which is turned on when the signal 4 generates a voltage change and turned off fixed time after the signal 4 disappears without generating any voltage change, to an apparatus which operates under the control of CPU 1 from a power supply output 8 through the switch 6. Accordingly, when abnormality occurs in the CPU 1, the signal 4 does not generate any voltage change and disappears and the switch 6 is turned off fixed time after the signal 4 disappears. Therefore, the power supply to the apparatus which operates under the control of the CPU 1 can be disconnected surely when abnormality occurs in the CPU 1.
Patent JP-S61134055-A (JP)
Title: Manufacture of semiconductor device
Inventor: YAMOTO HISAYOSHI
IPC: H01L21/8244
Filed: 1984-12-04
Abstract: PURPOSE:To bring the electric connection part of a semiconductor substrate into ohmic contact with the second polycrystalline Si layer, and to obtain high resistance values with the second polycrystalline Si layer, by a method wherein an oxide formed between the first polycrystalline Si layer at the time of forming the second one which contains oxygen is dispersed in the first and second polycrystalline Si layers. CONSTITUTION:A polycrystalline Si layer 19 which contains oxygen is formed on a polycrystalline Si layer 18 by pressure reduction CVD. At this time, the layer 18 is oxidized into an SiO2 layer 20 between the layer 19 which contains oxygen. Next, ions 21 are implanted to the connection part to reduce the connection resistance between a diffused region 17 with the layer 18. When the Si substrate 14 with the polycrystalline layers 18', 19 is thereafter heat-treated in N2, the Si crystal grains in the layers 18, 19 grow to Si crystal grains 22. Then, the SiO2 layer 20 changes into SiO2 lumps 23 and disperses into gaps among the Si crystal grains 22. This process eliminates the layer 20 and produces the ohmic connection of the polycrystalline layers 18 and 19 and eventually that of the layer 19 and the diffused region 17.

Title: Frame producing device
Inventor: FUKUDA AKIRA
IPC: H04J3/06
Filed: 1986-10-28
Abstract: PURPOSE:To speedily produce a frame with a large structure by permitting a shift register to give a control signal to a data selector which is inserted to the top of a small frame and selects control bits. CONSTITUTION:The reading of an n-bit counter 3 rises on a small frame basis. A k-bit counter 2 generates a preset signal at the top of one frame, and presets shift registers 7-9. A combination circuit 6 gives presetting values. Outputs S1-S3 from the registers 7-9 are connected to the select terminal R of the data selector 1. If the outputs are the same as the number theta of the input terminal of the selector 1, an input corresponding to the number theta shows up in an output W, and is temporarily stored in a D-FF 5. According to the number of the small frame outputted from the counter 3, the number theta of the selector 1 is selected. Thus an increase in gate delay time, which is caused by the use of complicated circuits, can be minimized.

Title: Microwave detector
Inventor: KAJITA YUICHI
IPC: G01R29/08
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain a microwave detector which can accurately detect extremely low radio waves. SOLUTION: When a signal which seems to be a microwave to be detected is detected at an output of a receiving part 2 of a double heterodyne system, an output voltage of an integrating circuit 12 becomes constant, and a sweep function starts. The output voltage is sampled by an A/D converter 4, and the number of samplings detected at the same position is stored in a memory 16. Since a sweep stop can be judged from a position which shows a large number of samplings, it can be judged that the sweep stop is effected at the same position if the number of samplings of equal level is large in a plurality of sweep periods, and it can be judged that a true microwave is detected.

IPC: H02M3/155
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To make it unnecessary to reset the relationship between the output voltage of a solar cell and a reference voltage in accordance with the constitution of the solar cell by connecting or disconnecting to this controlling device an element for setting a given value of an output voltage or the one for detecting the output voltage of the solar cell along with the solar cell. SOLUTION: The output voltage of solar cells 1 is inputted to the positive side of a comparator 4 and a reference voltage to its negative side so that the output voltage of the solar cells 1 is compared with the reference voltage. When the output voltage of the solar cells 1 is larger than the reference voltage, i.e., in the daytime, a switch 6 connects a load to the solar cells 1 so that it is driven by the solar cells 1. Conversely, when the output voltage of the solar cells 1 is smaller than the reference voltage, i.e., at night, a switching transistor 5 is turned off to release a coil L1 from excitation. As a result, the load 3 is connected to an auxiliary power supply 7 so that it is driven by the auxiliary power supply 7.

Abstract: PROBLEM TO BE SOLVED: To provide a remote authentication system and a remote authentication method which are highly reliable in security, and can surely authenticate an indivisual by means of biometrics information being the individual information of a user while protecting the biometrics information. SOLUTION: Since the biometrics information being the individual information of the user is ciphered and the biometrics information is transferred on a network 2 in a state decipherable only by an authentication server 3 specified by the user, the privacy of the user which is the biometrics information is surely protected in the form of reflecting the intention of the user. Also, since the date and time of preparing authentication information are confirmed in the authentication server 3, the illegal reuse of the authentication information is prevented. Further, since whether or not the authentication is performed by the authentication server 3 is confirmed on an authentication request side, thus this system is maintained high in security.

Abstract: PURPOSE:To organize a motor speed control circuit into a simplified circuit structure by the use of a CPU, by detecting the rotating speed and by measuring the time of waveform in integral multiples of the pulse. CONSTITUTION:A motor speed control device has a motor 1, a detecting means 2, a measuring means 3 and a control means 4, in which with the detecting means 2 the rotating speed of the motor 1 is detected as the change of a frequency response of pulse, with the measuring means 3 the time of waveform in integral multiples on high level or low level of pulse is measured. And with the control means 4 the measured value obtained by the measuring means 3 is compared with the set value. When the measured value is lower than the set value, the motor 1 is not driven for the next time. However, when the measured value is higher than the set value, the motor is driven accordingly.

Title: Data transmission method
Inventor: HIGUMA TOSHIYASU
IPC: H04L12/40
Filed: 1994-10-24
Abstract: PURPOSE: To attain transmission of predetermined information and to send other information than the predetermined information at a high speed. CONSTITUTION: A master station 1 reserves a data area for each slave station into a same frame upon a request from plural slave stations 21-23. When the master station 1 reserves a token circulating in a network, the master station 1 sends the predetermined information to each of the slave stations 21-23 by using the frame. Furthermore, each station sends other information than the predetermined information to a designated station when a token is reserved. Thus, an overhead as to the transmission of the predetermined information is less in this method and high speed transmission is attained. Moreover, since each station sends information by reserving a circulating token, abnormal increase in a wait time for information transmission is prevented.
