Patent JP-H0279518-A (JP)
Title: Hot standby switching system
Inventor: IGASAKI WATARU
IPC: H04B1/74
Filed: 1988-09-14
Abstract: PURPOSE:To reduce the cost and the power consumption by providing a control section controlling the operating state of a transmission section and reducing the power consumption of the transmission section when the transmission signal from the transmission section is totally reflected at a high frequency switch section. CONSTITUTION:When a high frequency switch section 6 selects the t signal from the transmission section 4, since the voltage standing wave ratio(VSWR) at the input terminal of the switch section is close to 1, most of the transmission signal applied passes as it is. However, when no transmission signal is selected, since the voltage standing wave ratio of the input terminal is deteriorated, the state reaches nearly the total reflection. Thus, the detected output detected by a reflection power detection section 5 is larger than a reference voltage Vref. In such a case, the control section 7 lowers the level of the transmission signal so that the detected output is coincident with the reference voltage Vref. Thus, the power consumption of the transmission section 4 is reduced and number of stages of diodes is decreased, then the cost is reduced.

Title: Voltage regulator circuit
Inventor: ERITSUKU JIEI DANSUTOROOMU
IPC: G05F3/30
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a voltage controller circuit which can handle load dump conditions and can be manufactured by using a low-voltage process by preventing a source voltage from reaching a load dump high voltage. SOLUTION: This controller based upon a band gap is constituted by having the 1st terminal part of its resistance R1-1 connected to a voltage Vcc. A 2nd voltage level shift circuit is constituted by connecting the drain of a transistor(TR) M102 to the 1st terminal part of a capacitor C14. A 2nd path element is constituted by connecting the collector of an NPN TR Q18 to a voltage VIN2. Consequently, the source voltage never reaches the load dump high voltage and is never exposed to high voltage conditions. Further, a 1st TR has its base grounded, so it can withstand a higher voltage under the load dump conditions, etc.

Title: Equipment having vibration generating source
Inventor: NAKAGAWA KENJI
IPC: F16F1/371
Filed: 1992-08-31
Abstract: PURPOSE:To sufficiently suppress vibration in vertical and horizontal directions by providing a leg of spherical unit or the like consisting of hard material. CONSTITUTION:An equipment provides a leg 54 having a vibration generating source, frame for supporting the vibration generating source, spherical unit 70 formed of hard material and rotatably mounted on the bottom surface of the frame, plate unit 84 arranged to come into contact with the spherical unit under the spherical unit 70 formed of hard material and a restricting member 58 formed of elastic material. The leg 54 includes caster part 56 and a mounting member 60. By rotating the equipment, the frame is vibrated, but vibration in a vertical direction of the frame can be suppressed by the spherical unit 70 or the like. Since movement in a horizontal direction of the frame can be ensured by rolling the spherical unit 70 on the plate unit 84, vibration in a horizontal direction, transmitted to a floor, can be absorbed. Further, since force of restricting moving the caster part 56 by the restricting member 58 is increased in accordance with increasing amplitude in the horizontal direction, lateral deflection of the frame can be small suppressed.

Abstract: PURPOSE:To reduce an offset voltage to be generated by the charge injection of a switch by newly providing a differential input for correction in a buffer amplifier and respectively providing fundamental sample-and-hold circuits in the positive side and negative side input terminals of the differential input for correction. CONSTITUTION:In a buffer amplifier 7 of the sample-and-hold circuit, a differential input terminal 4-1 for correction is provided so that a voltage to cancel the offset in the size of qft/C generated in the sample-and-hold circuit can be impressed to the differential input terminal 4-1 for correction. In such a case, the qft is a channel charge and the C is the capacity value of a capacitor. In order to generate a voltage for correction, the sample-and-hold circuits are connected to the positive side and negative side of a correction input terminal 1-1, for example, so as to execute the sample-and-hold of the input voltage, and the size of the sampling hold switch on the negative side is made double. Thus, the offset voltage can be reduced while including the input voltage dependency of the channel charge.

Title: Semiconductor relay operation control device
Inventor: MINAMI TOSHINORI
IPC: H01L33/00
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To use a semiconductor relay in place of a mechanical relay. SOLUTION: A predetermined operation start delay time (ta) is set in an operation start delay time setting part 13, and a predetermined operation stop delay time (tb) is set in an operation stop delay time setting part 14. When an operating voltage signal 2 is input from the outside, an operating voltage detecting part 12 detects that operating voltage input, and an operating timing part 15 starts counting time at the detection of the operating voltage input and, after the elapse of the operation start delay time (ta), outputs an operating signal 5 to a semiconductor relay 1 to operate the semiconductor relay. When the input of the operating voltage 2 is stopped, the operating timing part 5 starts counting time and, after the elapse of the operation stop delay time (tb), stops the operating signal output 5 to the semiconductor relay 1 to stop the action of the semiconductor relay.  Thus the semiconductor relay 1 is operated in a desired response time Ta and restoration time Tb in response to the input of the relay operating voltage signal 2 from the outside and is stopped.

Abstract: PURPOSE:To enable measurement handily and in a wide range, by determining the ratio and difference between contribution rates of radiation sources which are difined as the ratio of difference between detection values of a scan type radiation thermometer as given when two radiation energies are incident on the thermometer from the radiation sources and when none is. CONSTITUTION:A scan type radiation thermometer 2 scans over an object 1 to be measured and feeds a output signal to an arithmetic means 6 corresponding to measuring positions. Here, output signals of radiation sources 31 and 32 when radiation thereof is reflected from the object 1 being measured are represented by E1 and E2 and those below them E0. Output signals of a temperature detector 5 which detects temperature signals Tr of the radiation sources 31 and 32 and a temperature signal Ta of a background radiation plate 4 are also fed to the arithmetic means 6. Then, the arithmetic means 6 determines the ratio of contribution rates of the radiation sources from the signals E0 and E1 and E2 to match a specified formula and further the emissivity epsilon by computation. The emissivity epsilon is used to determine the temperature T of the object 1 being measured by computation. In this manner, the emissivity epsilonof the object 1 being measured is determined from the contribution rates of the radiation sources 31 and 32 to obtain temperatures T at points.
