Title: Pulse arc welding machine
Inventor: MIZUNO KOUJI
IPC: B23K9/09
Filed: 1980-07-08
Abstract: PURPOSE: To supply current as well from a pulse current supply source through opening and closing of two switches and simplify a power source device by connecting a series body of a switching element and an inductance in parallel to a switching element connected in series between a DC power source and an arc part.  
     CONSTITUTION: When a switching element 14 is closed, current flows in the route of a DC power source 13, the element 14, an inductance element 16, an electrode wire 3, an arc part 5, base metals 4, and the power source 3. Next, when the element 14 is opened, the current flows in order of the routes 16, 3, 5, 4, 17, 16 until there are no more dynamic currents by the reactance component in the circuit. The inductance 16 is not always required. On the other hand, the circuit by a switching element 15, an inductance 12 and a diode 18 in parallel with the element 14 is a base current supply circuit which supplies base current to the arc part 5.

Title: Insulated-gate semiconductor device
Inventor: MOMOTA SEIJI
IPC: H01L29/78
Filed: 1992-04-14
Abstract: PURPOSE:To improve the breakdown strength of a MOS-FET or IGBT which is turned on and off by a current controlled by the MOS structure on the surface. CONSTITUTION:A resistor 11 whose resistance is lowered at a high temperature is connected between a gate electrode 7 and an emitter electrode 9. When a device temperature is elevated, the gate electrode and the emitter electrode 9 are short-circuited and a gate voltage is lowered. With this process, a collector current is reduced, the operation of a parasitic bipolar transistor or a parasitic thyristor is suppressed and a breakdown can be avoided. The resistor 11 is made of polycrystalline silicon which is the material of the gate electrode 7 and impurities are introduced into the part of the gate electrode 7 only to lower the resistance of that part at a room temperature.

Filed: 1984-05-10
Abstract: PURPOSE:To automatically take out a recording medium from its case, by providing a means which controls a cover locking means to unlocking condition in a segment of its carrying route when the cover locking means is carried in one direction by a carrying means. CONSTITUTION:In a recording disk reproducing device, cover locking members (cover locking means) 99 and 100 are controlled to an unlocking condition in the extent of a segment of the carrying route of the members 99 and 100, when a movable base (carrying means) carries the members 99 and 100 in one direction. Namely, the cover locking members 99 and 100 are respectively supported by pins 105 and 106 so that they can make horizontal rotation to the movable base. Under a ''cover and disk holding condition'', the following terminals 115 and 116 of the cover locking members 99 and 100 are respectively guided by cam grooves 113 and 114 and the members 99 and 100 are set to positions which control the cover. Therefore, a disk holding mechanism 90 can take three different conditions of ''cover and disk holding condition'', ''cover holding condition'', and ''non- holding condition'' and a recording medium can automatically be taken out from its case.

Title: Method and apparatus for detecting wetting condition of pavement
IPC: G01N21/55
Filed: 1992-03-19
Abstract: PURPOSE:To make it possible to detect the wetting condition of pavement by rotating a polarizing plate, and measuring the intensity of the polarized component of light reflected on the pavement. CONSTITUTION:For example, a polarizing plate F is set at incident angle (i)=reflecting angle (j)=60 degrees. The angle is brought close to the Brewster angle of a water surface so as to obtain an intensity difference of polarization as great as possible. The plate F is rotated with a motor D. Pavement reflected light R is transmitted through the polarizing plate F and received with a photoelectric conversion element N. An AC voltage E corresponding to the intensity of the polarized component is outputted from the element N. A measuring means H measures the change in output voltage from the element N. When the pavement U becomes wet, the amount of the pavement reflected light is increased as compared with a dry pavement U. Therefore, the output voltage from the element N is increased, and the reflectivity of the polarized component of the P polarized light, which is in parallel with the incident surface, is attenuated. However, the reflectivity of the polarized component of the S polarized light, which is orthogonal to the incident surface, becomes higher than the P polarized light. Thus, the change in output voltage can be excellently detected. In this way, the wetting condition of the pavement can be excellently detected.

Title: Pot type kerosene burner
Inventor: NAKAMURA KAZUHARU
IPC: F23D5/04
Filed: 1982-06-01
Abstract: PURPOSE:To enable the instantaneous extinguishing of fire, by a method wherein a kerosene feed pipe, extending further from a connection between a kerosene pipe and an air pipe, is reduced in a diameter to form a kerosene feed nozzle, while the tip thereof is protruded into a pot, and the base surface of the pot is normally kept in a dry state. CONSTITUTION:A pot 1, having a number of pores 1' in a side wall, is installed in an air duct 2. A kerosene feed pipe 3 and an air pipe 4 are then interconnected, and the kerosene feed pipe 3, further extending from the connection, is reduced in a diameter to form a kerosene feed nozzle 5, and the tip thereof is protruded into the pot 1. A gap 6 is provided between the kerosene feed nozzle 5 and the side wall of the pot 1. When kerosene and the air are fed into the pot 1 for mixing, the mixture forms fine particles which are jetted into the pot 1 for instantaneous combustion since the kerosene nozzle 5 is reduced in the inner diameter. Thus, the base surface of the pot 1 is normally kept in a dry state and prevents kerosene from being adhered thereto, instantaneous extinguishing of fire is possible when the supply of kerosene is stopped.
