Patent JP-H01204477-A (JP)
Title: Field-effect ultrahigh-frequency semiconductor device
Inventor: WASA KENJI
IPC: H01L21/338
Filed: 1988-02-09
Abstract: PURPOSE:To reduce a pellet in size by independently insetting input/output impedance matching circuits to N (N>=2) pieces of basic cells connected in parallel with each other. CONSTITUTION:Basic cells in which series circuits of N-square spiral inductance elements 4 (N>=2) made of pectinated electrode field-effect transistors and capacity elements 5 of thin film multilayer structure are inserted as matching circuits, are connected in parallel, and independently inserted to all the inputs and outputs of the cells 10. Thus, since each cell 10 can be impedance-matched, the input/output impedance matchings can be conducted in more accurate state. Accordingly, originally preferably characteristics of the FET can be employed in an external circuit at the points of gain, band, etc., as compared with the simultaneous matching of a conventional multi-cell field-effect transistor(FET). In this manner, the area of the pellet of the FET can be reduced.

Title: Robot controller
Inventor: MIZUTANI TOMOJI
IPC: G05B19/42
Filed: 1989-02-08
Abstract: PURPOSE:To shorten the tact time of a robot by parallel-processing respective types of data concerning a signal output, the operation of a robot main body, and other robot controls. CONSTITUTION:A robot operation control part 3 applies the position of a robot main body 7 and output JIG designation as JIG output conditions to a signal output condition supervising part 8 when an operating procedure stored into an operating procedure storing part 2 is executed, and the robot main body 7 is moved. A signal output condition supervising part 8 supervises the position of the robot main body 7, checks whether the robot main body 7 has passed through a position applied as the Jig output conditions, when it has passed, the signal is outputted (Jig output) to the designated output JIG. Thus without stopping at the JIG output position, since the signal is outputted (JIG output) and continuously moves, extra acceleration/deceleration is made unnecessary, and the tact time is shortened.

Title: Monitor circuit for level of multi-value orthogonally amplitude modulated wave
Inventor: ISHII TAKU
IPC: H04L27/38
Filed: 1985-02-18
Abstract: PURPOSE:To eliminate a maloperations and the troublesomeness of manual operations by using a detector for the level of an input wave, an indicating part which indicates the output of the detector via a level converter and a discriminator which discriminates whether the input wave is equal to a multi- value QAM wave or a carrier wave and short-circuits the level converter in the case of the multi-value QAM wave. CONSTITUTION:The wave detectors 11 and 12 fetch the envelope curve component (amplitude component) of a part of the fetched output wave of a a primary intermediate frequency amplifier 5. A capacitor 13 prevents the DC component of the output wave and applies this wave to a rectifier 14 and a capacitor 15 for the acquisition of the variance of the amplitude. Then a certain amount of DC voltage and the DC voltage of OV are obtained when the input wave of a terminal IN is equal to a multi-value GAM wave and a carrier wave respectively. Here the voltage is applied to a comparator 16 and a relay 17 works only with the multi-value QAM wave. Then a level converter 8 is short-circuited at the contact r1 of the relay 17. While the relay 17 is hardly actuated with the carrier wave. Thus the converter 8 is put into a meter 10.

Title: Heat treatment for metal matrix composite material
Inventor: KOBAYASHI TOSHIRO
IPC: C22C47/00
Filed: 1993-02-19
Abstract: PURPOSE:To control strength, ductility, fracture toughness, and the balance among them by specifying heat treatment conditions for a metal matrix composite material where ceramics and metal are used as reinforcement. CONSTITUTION:A metal matrix composite material where metal or alloy is used as matrix and ceramics and metal are used as reinforcement, is subjected to solution heat treatment and rapidly cooled, and, in the course of subsequent aging treatment, the composite material is heated at a temp. between aging temp. and solution heat treatment temp. to undergo reversion treatment. At this reversion treatment, temp. and time are changed in the range of 190-260 deg.C and in the range between several seconds and several tens minutes, respectively, by which strength, ductility, fracture toughness, and balance among them can be arbitrarily controlled. Further, because the addition of simplified reversion treatment for a relatively short time between several seconds and several tens minutes to the conventional process, such as T6 treatment, suffices for this method, this method has the advantage of requiring not much change in the number of stages, costs, etc., as compared with the conventional method.

Filed: 1984-02-21
Abstract: PURPOSE:To make it possible to detect the concn. of a high concn. suspended substance, in the optical measurement of the concn. of the suspended substance contained in waste water, by allowing laser beam to be incident to the interface of a measuring liquid and detecting the size of the beam image generated to an interface by reflected and scattered beam of said laser beam. CONSTITUTION:Laser beam 4 of He or Ne is incident to the interface 8 of a liquid 1 containing a suspended substance and a glass plate 7 from a beam source 5, and reflected and scattered by the suspended substance to generate a circular beam image 6 at the interface 8. As the concn. of the suspended substance becomes high, the radius of the beam image 6 becomes small. Hereupon, an optical fiber 9 is arranged in the radius direction of the beam image to detect the size of the radius of the beam image and the concn. of the suspended substance is operated by an operation apparatus 13. Because measuring beam is projected to the interface to detect the beam image, this measuring mechanism is different from a method for measuring the attenuation of beam transmission by the suspended substance and even the high concn. suspended substance can be measured with high accuracy.
