Title: Connecting method of insulation covered wire to armature terminal
Inventor: HASHIMOTO YOSHIMI
IPC: H02K3/38
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To make connecting capable and attain automation without removing insulation coating of an insulation covered wire, by locking it in a condition with the insulation covered wire left as provided in a terminal, burning this locked part, thereafter making a melted brazing material adhere to the locked part, and forming a brazing connection part. SOLUTION: A terminal wire 3a of an insulation covered wire constituting an armature 3 is locked to be wound to a terminal 4 in a condition with insulation coating left as provided. After a locked part of the terminal wire 3a is burned with a flame 9 of a burner 8, a high melting point brazing material 10 is melted by the flame 9 to adhere to the locked part, and a brazing connection part 11 is formed. When the locked part locking the terminal wire 3a of the insulation covered wire to the terminal 4 is thus burned, the insulation coating burned at a high temperature changes into ashes, this ash is blown off by a blow pressure of the flame 9, and a core wire is exposed so as to eliminate necessity for particular removing work of the insulation coating. Adherence can be made by the melted brazing material, and connecting work can be automated.

Title: Gear train structure of electronic watch
Inventor: NABEYAMA TAKATOSHI
IPC: G04B19/25
Filed: 1983-03-04
Abstract: PURPOSE:To enable easy and sure date correction by providing a slip mechanism in a time difference hour wheel. CONSTITUTION:A minute wheel 10 engages with a minute pinion 8a of center wheel 8 and an hour wheel gear 9a of a time difference hour wheel 9. The time difference hour wheel 9 consists of an hour wheel gear 9a and an hour wheel 9b and has a slipping function section 9c that is slipped by load of above specified torque between the hour wheel gear 9a and hour wheel 9b. When a crown is pulled out to the first step position, rotation of the crown is transmitted to the hour wheel 9b of the time difference hour wheel 9 from a correcting wheel 18 through an intermediating correcting wheel 15 and an intermediating wheel 11. As the hour wheel gear 9a of time difference hour wheel and the hour wheel 9b have the slipping function section 9c, the hour wheel gear 9a slips and does not rotate, and only the hour wheel 9b rotates. Accordingly, only the hour hand can be corrected independently with the minute hand and second hand continuing normal operation.

Abstract: PURPOSE: To precisely measure the mass of iron particle contained in a circulating liquid system by using a coil wound around a magnet as a probe, and measuring the change of inductance value of the coil by the access of iron particle. CONSTITUTION: A magnet 67 is contained in the body 65 of a sensor 78, and the line of magnetic flux is sent to a collecting surface 60 through a magnetic pole piece 61 to form an attractive magnetic band near the surface 60.

Title: Semiconductor device
Inventor: SAITO MASAYOSHI
IPC: H01L27/02
Filed: 1986-02-18
Abstract: PURPOSE:To remove a current by a power terminal by forming the same conductivity type diffused layer as a diffused layer for forming a diode on the periphery of an overvoltage input protective diode, and connecting the diffused layer with a voltage source of a reverse voltage level to a substrate potential to efficiently absorb the current before affecting the influence to a peripheral circuit. CONSTITUTION:A peripheral diffused layer 2 is connected through an electrode 4 with a reverse level to a power line. When a semiconductor substrate 6 is made of an N-type semiconductor, the diffused layers 1, 2 are of P-type, the substrate 6 is connected with a high potential (VDD), and the electrode 4 is connected with a low potential (VSS). When a voltage higher than the VDD is applied from an input terminal to an electrode 3, a protective diode becomes a forward bias so that a current flows to the substrate 6, a current flows to the layer 2 due to the operation of a parasitic PNP transistor generated at this time and is absorbed to the VSS. Similarly, when the substrate 6 is made of a P-type semiconductor, the layers 1, 2 become N-type, and the current flowing to the layer 2 is absorbed to a power source.

Title: Reflecting type light sensor
Inventor: MARUYAMA JIYUICHI
IPC: G01S7/48
Filed: 1982-03-03
Abstract: PURPOSE:To maintain an electrical signal and the signal-noise ratio at a fixed value  regardless of the surface condition of an object to be measured by controlling the  output of a pulse oscillator driving a light source according to the intensity of a reflected light received. CONSTITUTION:A reflected light on an object 4 to be measured is converted into an electrical signal with a light receiving element 6 passing through an optical system  5 on the light receiving side. After the effect of the disturbing light is removed with a  band pass filter 7, the light is amplified with an amplifier 20 and then, sent to a pulse  width modulating circuit 21. This electrical signal contains variations due to the surface condition of the object to be measured. The pulse width modulating circuit 21  modulates the pulse width in such a manner that a pulse of a certain frequency is inversely proportioned to the level of the electrical signal. In other words, when the  electrical signal is strong, the pulse width is decreased while when it is weak, it is  increased. A light source 2 emits light receiving a pulse thus modulated. As the light emitting time of the light source 2 at each unit cycle corresponds to the pulse width,  the light emitting time at each unit cycle is reduced resulting in a decrease in the  quantity of light when the electrical signal is strong but in a increase therein when it is weak.
