Title: Manufacture of ceramic sheet
Inventor: ADACHI MASAHIKO
IPC: B28B1/30
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To realize the favorable separation of a ceramic coating layer without forming a coating layer on a sheet base material. SOLUTION: This ceramic sheet used as the production material of a laminated chip part is manufactured by forming a ceramic coating layer 12 through the application of a ceramic slurry prepared by kneading a ceramic powder with a solvent on the surface of a sheet base material so as to dry and solidify the ceramic coating layer 12 by heat-treating its front side in order to separate the resultant ceramic coating layer 12 from the sheet base material 2 for obtaining the ceramic sheet. The separation of the ceramic coating layer 12 is performed by blowing off hot air from air nozzles 20 provided at the positions opposing to the boundary part 18 between the ceramic coating layer 12 and the sheet base material 2 so as to blow the hot air in the boundary part 18.  Thus, since the portion to be separated of the ceramic coating layer 12 is heated, dried and separated at separation, the separation can be favorably performed even when no coating layer is present on the surface of the sheet base material.

Title: Cmos amplifier
Inventor: KURATA KATSUMASA
IPC: H03F3/16
Filed: 1985-05-08
Abstract: PURPOSE:To avoid the effect on a minimum operating voltage due to variation of a threshold voltage of a transistor (TR) and the fluctuation of the voltage gain by connecting a current mirror circuit comprising TRs of opposite conduction type to TRs connected to an inverting amplifier circuit to said TR and applying negative feedback to the inverting amplifier circuit from a resistor at the output of the mirror circuit. CONSTITUTION:An output of a CMOS inverting amplifier circuit connects to a gate of an N-TR 10 and a gate of a TR 11 of the current mirror circuit, and a drain of a TR 12 is connected to a resistor 13 and a resistor 14 from which negative feedback is applied to the inverting amplifier circuit. Thus, the DC operating point of the inverting amplifier circuit is stabilized by the negative feedback. Further, in selecting the relation of (2/R3betaN2).(betaP2/betaP3)<< VTN, the TR 10 is not limited by the minimum operating voltage due to a gate potential V1 independently of the threshold voltage, where R3 is a resistance of the resistor 13, betaN2,betaP,betaP3 are gain factors of the TRs 10,11,12 and VTN is a threshold voltage of the N-TR. Further, the voltage gain is not decreased under the condition that the inverting amplifier circuit is operated at the saturation region and a stable gain is obtained. The operating voltage VDD has only to satisfy the relation of VDD>TTN-VTP in this way and no gain reduction is caused to variation of the VTN.

Title: Ground fault protection system for distribution line
Inventor: NISHIJIMA KAZUO
IPC: H02H3/38
Filed: 1991-04-30
Abstract: PURPOSE:To detect a faulty section of a distribution line and to eliminate a power breakdown in a normal section when separating the faulty section by providing on a switch installed along a distribution line a protective relay element having a timer for coordination and a pole-mounted protective device having a function to communicate with normally open switches. CONSTITUTION:The plurality of section switches are dispersedly located along a distribution line. In the distribution system wherein a switch DM7 for communicating with other distribution lines is installed, section switches DM2, DM5 and DM7 are provided with protective devices 1, 3 and 2 respectively. When the protective devices RY 1, 2 and 3 detect a fault, they get started to work to set a releasing timing of the breakers. A fault detecting timer is so set as it may be shorter than a working time of a distribution line pullout relay and the protective devices located remoter from the power supply side may work shorter. By this method, when a recoverable instantaneous ground fault (contact by trees, etc.) occurs, there is no power breakdown.

Title: Electronic speed meter for vehicle
Inventor: OKABAYASHI SHIGERU
IPC: G01P3/42
Filed: 1980-07-21
Abstract: PURPOSE:To improve response of a display and to prevent flicker by utilizing a time constant controlling circuit comprising a nonlinear resistance element, in which the value of the resistance decreases with an increasing car speed and a capacitive element in an electronic speed meter for a vehicle. CONSTITUTION:A car speed pulse from a car speed sensor 9 is shaped to constant width in a monostable multivibrator 8 and with a condenser 6 and a resistance 7, a discharge voltage proportional to a car speed is obtained. When, with a rapidly increased car speed, an output of a buffer amplifier 18 is increased guickly, all of zener diodes 10-12 conduct, a time constant for charging of a condenser 17 becomes relatively small because a parallel synthesized resistance of resistances 13-16 is small and thus response of a display is improved. For a fine variation of a car speed when running with a constant speed, all of the zener diodes do not conduct, a charging time constant of the condenser 17 is determined by the resistance 16, and because it becomes relatively large, flickering of the display is prevented.

Title: Bath heater with circuit coupling hot water supply
Inventor: KOMAKI YASUSHI
IPC: F24H1/00
Filed: 1990-04-17
Abstract: PURPOSE:To shorten hot water supply time by continuously supplying hot water and adjust the amount of the hot water supply by estimating the amount of water left behind in a bath tank based upon stored water level-flow rate data by directly coupling a hot water supply circuit using a hot water heat exchanger and the bath tank via a bath heat exchanger, and increasing passage areas of a water jacket part of the bath heat exchanger and of a circulation pipe. CONSTITUTION:A hot water supply circuit 16 by a hot water heat exchanger 2 and a bath tank are connected via check valves 18, 21, a vacuum braker 19, a hot water injection solenoid valve 20, and a bath heat exchanger 3, and passage areas of a water jacket part of the heat exchanger 3 and of a circulation pipe 4 are increased so as not to be influenced by dynamic pressure during hot water injection. A water level sensor 23 for detection of bath tank water level is disposed on the water jacket part or on the circulation pump 4. Since the hot water supply at 16 and the bath tank 5 are directly coupled, an accumulated flow rate of a flow rate sensor 12 and a bath tank water level correspond at all times. Accordingly, an accurate water level can always be detected even during the hot water injection, hot water injection time can be shortened and the amount of the hot water injection can be adjusted by estimating a tank remaining water amount based on water level-flow rate data.
