Title: Handset
Inventor: ADACHI SHIZUO
IPC: H04M1/22
Filed: 1992-01-24
Abstract: PURPOSE:To make it possible to easily confirm the location at the time of a power failure and to easily operate a telephone set at a dark room. CONSTITUTION:When a power failure occurs, a microcomputer 24 detects the gentle voltage drop of a charging circuit 22 and outputs a high level power failure detection signal to the base of a transistor 25. Due to this, the transistor 25 is turned on and light is emitted from a lamp 26. When a slave machine is lifted from a charging base 1, a microcomputer 24 detects the rapid voltage drop of the charging circuit 22 and outputs a high level handset lifting detection signal to the base of a transistor 27. Thus, the transistor 27 is turned on and light is emitted from a lamp 28.

Title: Valve gear with switch
Inventor: KASATANI MASASHI
IPC: F01L9/20
Filed: 1984-02-28
Abstract: PURPOSE:To make an electrical insulating state maintainable over a long period of time in a stable manner, by forming a thine film layer with a physical evaporation process such as an ion plating method or the like. CONSTITUTION:A surface and its vicinities of a covered layer 26 consists of zircon oxide (ZrO2), but oxygen content O inside the covered layer 26 comes to being small in proportion as its internal state approximates to the surface of a valve body 8 whereby on the surface of the valve body 8, it comes to have such a sectional structure as having zircon alone. In consequence, a degree of insulation for a portion consisting of a compound between the required metal and reactant gas is continuously high toward the wall surface side of a guide hole 7 from the surface side of the valve body 8. A metallic layer region I is coveredly attached to the metallic valve body 8 with very strong cohesion, while a region IImakes insulation and abrasion resistance between the valve body 8 and a nozzle body 6 securable, therefore these regions I and II different in characteristics are strongly connectable owing to a region III.

Title: Video signal processing circuit
Inventor: AKABOSHI TSUKASA
IPC: H04N7/18
Filed: 1980-03-19
Abstract: PURPOSE:To utilize a part of the video signal, which is supplied to the ITV monitor having a high sensing performance, to generate the alarm signal for the abnormal phenomenon, by providing two kinds of reference luminance data setting circuit. CONSTITUTION:Integrating circuit 3 outputs a voltage proportional to the luminance level at the sensing point just before picture switching, and this output is converted to a digital value by analogue-digital converting circuit 4. Digital delay circuit 5 delays luminance data at the sensing point by an arbitrary frame interval, and differential luminance data between the luminance level before (t) seconds and the latest luminance level is obtained by digital difference circuit 6. This differential luminance data is compared with data of two external reference luminance data setting circuits 7 and 8 by digital comparing circuit 9. Consequently, since the output of comparing circuit 9 limits the change the luminance level at the sensing point in detail, a great change of the illumination intensity due to the environmental change other than the abnormal phenomenon in the field is eliminated.

CONSTITUTION:First, a voltage to be used as a reference to an a-phase is applied from a test terminal installed on a board for a fault-point orientation apparatus 1. Then, a current I1 whose phase is the same as that of the a-phase voltage is made to flow to the primary side of a zero-phase current transformer ZCT, and data on the actual value I2 of a secondary current is detected by a data collection unit. Then, a specific error epsilon is detected, the logarithm of the secondary-side actual value I2 is plotted on the x-axis, and the specific error epsilon is plotted on the y-axis. For example, a computation based on the method of least squares is performed, and its computed value is apporximated by one straight line. The inclination (a) and the intercept (b) of the stright line are used as settling values, a computaiton is performed and a computed value is output to a correction circuit 12.

Filed: 1982-03-08
Abstract: PURPOSE:To achieve a separate safety treatment in case of a trouble by providing a safety device for front and rear wheels to cut off separate operation sources immediately detecting the trouble of antilock controllers for front and rear wheels. CONSTITUTION:Antilock controllers 105 and 205 for front and rear wheels are operated independently of each other.
