Title: Voltage nonlinear resistor porcelain composition
Inventor: SAWAZAKI AKIRA
IPC: C04B35/46
Filed: 1990-07-20
Abstract: PURPOSE:To obtain temperature characteristics wherein varistor voltage does not decrease but increases, or change does not exist at all, when temperature is increased, by containing, in Sr(1-x)PbxTiO3, a specified amount of one or more of metal oxides of Nd2O5, Ta2O5, and WO3, or a group composed or rare earth oxide. CONSTITUTION:For 95-99.99mol% led titanate strontium Sr(1--x)PbxTiO3 (0.10<=x<=1.00) (first component), 0.001-5.000mol% metal oxide (second component) is contained, which is selected out of the following; niobium oxide Nb2O5, tantalum oxide Ta2O5, and tungsten oxide WO3, or rare earth oxide R2O3 (R is at least one of metal oxide selected out of a group composed of Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu). The first component mainly contributes to the temperature characteristics of varistor voltage, and the second component is metal oxide which mainly contributes to the formation of semiconductor. Hence, when a varistor is formed of magnetic composition containing the first and the second components, the temperature characteristics of varistor voltage can be improved.

Title: Fin structure of boiler wall pipe
Inventor: HASHIMOTO MASAMITSU
IPC: F22B37/20
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of the crack of a fin at the coupling part of a wall pipe group and to improve reliability by a method wherein adjoining wall pipes are coupled through a member bent at a specified angle at the final ends of fins in an axial direction of the wall pipe. SOLUTION: In a coupling part, a water wall pipe 6 and a wall pipe 7 on the cage side are welded at a weld part 8 to a final end part welded by a fin 9 and a reinforcing material 14 bent at a bending angle θ in the axial direction of the wall pipe is welded at a weld part 88 to a water wall pipe 6 and a wall pipe 7 on the cage side. Provided a bending angle θ of a reinforcing material 14 is 90 deg., stresses A, B, and C of each part are similarly reduced in a balancing state. Provided the bending angle θ is below 90 deg., lowering of the stressed A and C is slackened and the increase of the stress B is also slackened, whereby it is desirable that the bending angle θ is reduced to a value below 90 deg.. This constitution reduces a stress at the final end of a fin and suppresses the occurrence of the crack of the fin.

Inventor: MIZUKI SHINYA
IPC: H05B33/10
Filed: 1992-06-26
Abstract: PURPOSE:To provide a thin film EL display element by which high brightness emission becomes possible by low voltage impression. CONSTITUTION:A thin film EL display element 100 is formed by laminating a transparent electrode 12, the first emission layer 13, the first and the second insulating layers 14a and 14b, the second emission layer 15 and a back plate 16 in order on a glass substrate 11. In the thin film EL display element 100, The insulating layers are formed substantially as a single layer of the first and the second insulating layers 14a and 14b, so that a voltage drop can be reduced in the insulating layers.

Title: Running guiding apparatus for vehicle
Inventor: HIROTA MASAHARU
IPC: G01C21/00
Filed: 1991-08-01
Abstract: PURPOSE:To obtain a vehicle guiding apparatus which guides a vehicle to the most suitable intersection even when there are a plurality of intersections led to the next passing point, thereby to precisely guide the vehicle per every intersection to the destination. CONSTITUTION:Waves from a road beacon 100 set in the vicinity of an intersection are, through an antenna 10 and a beacon receiver 12, input to an operating device ECU 16. A ROM of the ECU 16 stores the connecting relationship and the connecting distance of spots used for the guiding data of the road beacon, and the connecting relationship and the connecting distance of intersections within the spots. The ECU 16 retrieves from the stored connecting relationship the shortest route to a target intersection designated by an operating part 18 and stores the route as a string of the spots including the data of the intersections. The advancing direction at the intersection is instructed by an arrow or sound as the guiding data from the road beacon and the shortest route are compared.

Title: Printer
Inventor: UTSUI OSAMU
IPC: B41J29/38
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To detect abnormal operation of a motor without requiring any extra motor by providing means for stopping a motor when a comparing means detects a fact that the temperature of a motor driver exceeds a reference temperature for stopping the operation of the motor. SOLUTION: A CPU 9 actuates a monitor system for monitoring the temperature of a motor driver 8 before a motor is operated. The temperature rises when a motor is operated through a controller and a carriage can not reach a specified position if an obstacle is present. Since the motor driver 8 supplies a carriage motor 3 continuously with a specified amount of current, an overcurrent flows to cause temperature rise. When the temperature of the motor driver 8 exceeding a reference temperature for stopping operation of the motor is detected, the monitor system issues an interruption for stopping the controller forcibly. When the motor completes the operation normally, the controller issues an interruption for stopping the monitor system.

Title: Noise eliminator in suction-exhaust system for automobile, etc.
Inventor: NUNOSHITA HARUO
IPC: F01N1/00
Filed: 1987-07-31
Abstract: PURPOSE:To dispense with a muffler as well as to reduce the extent of exhaust resistance by emitting an offset soundwave from a speaker installed an exhaust system according to each signal out of a torqueconverter and a tachometer. CONSTITUTION:A signal out of a torqueconverter 4 is inputted into a controller 8 via an amplifier 6 and an analog-to-digital converter 7, while a signal out of a tachometer 5 is also inputted thereinto. The controller 8 reads offset soundwave data conformed to both detection signals from a memory, emitting an offset soundwave out of a speaker 9 installed in an exhaust system via an analog-to-digital converter 11 and an amplifier 10. With this constitution, a muffler is no longer required and exhaust resistance is reduced, while since there is unnecessary to install a microphone in the exhaust system, cost is thus reducible.

Title: Electric contact material
Inventor: TSUJI HITOSHI
IPC: H01H1/023
Filed: 1981-12-02
Abstract: PURPOSE:To obtain an electrical contact material superior to a conventional Ag-Ni contact material in hardly dissipative property and welding resistance  by adding a prescribed percentage of Ni to Ag and by dispersing a prescribed  percentage of >=1 kind of alkali metallic oxide. CONSTITUTION:This electrical contact material is obtd. by adding 10-60wt% Ni to Ag and by dispersing 0.0001-0.3wt% of >=1 kind of alkali metallic oxide such as Li2O. Since the alkali metallic oxide is a compound which has a small work function when thermions are emitted and is liable to cause electric discharge, by dispersing said very small amount of the oxide, the oxide is allowed to preferentially generate arc when electrical contacts are brought into contact with each other and separated. Accordingly, arc is dispersed over the whole surfaces of the contacts without causing concentration on a point, and the contacts can be uniformly dissipated little by little. This electrical contact material can maintain low contact resistance equal to that of said conventional electrical contact material.
