IPC: G03G15/06
Filed: 1982-01-27
Abstract: PURPOSE:To obtain recorded images having stable image quality even if the surface potential of a photoreceptor fluctuates by detecting the surface potential of the photoreceptor prior to projection and exposure after electrostatic charging and setting developing bias stepwise in accordance with the detection signal thereof. CONSTITUTION:A potential sensor 5 is driven by a potential detecting circuit 6 to detect the surface potential of a photoreceptor 1 prior to projection and exposure of images after electrostatic charging and transmits the detection information thereof to a circuit 6. In accordance with said information, the circuit 6 oututs the information on the surface potential of the photoreceptor to a control circuit 7. The circuit 7 opens a gate to accept the output of the circuit 6 and to output the information thereof to a developing bias control circuit 8 at the specified timings before the the electrostatic latent images formed by each time of exposure irradiation, thereby changing the developing bias of a developing sleeve 4a. If the developing bias is maintained constant during developing by setting the developing bias to be changed with a change in the charging potential of the photoreceptor 1 prior to developing of each time of electrostatic latent images in the above-mentioned way, less influences of noises, etc. are received, and the image quality of the recorded images is stable and good.

Title: Polyester composition
Inventor: YAKUSHIJI HIROSHI
IPC: D01F6/92
Filed: 1988-01-19
Abstract: PURPOSE:To obtain a polyester for fiber or film, improved in its tendency to increase the pressure of filtration by decreasing filter clogging during spinning or film formation, by decreasing the size of an Sb metal particle added to a specified polyester. CONSTITUTION:The title composition comprises a polyester mainly consisting of ethylene terephthalate repeating units, 1-50ppm polygonal Sb metal particles of a major diameter of 0.01-1mu and 10-500ppb of Bi element. Since the Sb metal particles in this composition are fine and uniform, filter plugging during film formation or spinning can be decreased, and the life of filter can be prolonged. When this composition is formed into a film, the number of coarse protrusions on the surface is small and the hue is good. Yarn break can be reduced during spinning and after-processing because the number of coarse particles originating in the Sb metal particles is small, and a fiber product having a good hue and stable quality can be obtained.

Title: Motor driving igbt module
Inventor: AISAKA TOSHIFUMI
IPC: H02H3/20
Filed: 1994-02-02
Abstract: PURPOSE:To protect an IGBT module by a method wherein the IGBT module is composed of an FRD and an IGBT which has a larger energy strength for a unit area than the FRD and an energy produced by a sharp overvoltage caused by an avalanche breakdown is consumed by the IGBT. CONSTITUTION:A power supplied from a 3-phase or single-phase power supply 1 is converted into a DC power by a converter unit 2 and, further, inverted into an AC power by an inverter unit 3 to control a motor 4. An overvoltage protective circuit 5 detects the output voltage of the converter unit 2 and, if the detected voltage exceeds a specified value, stops the operation of the inverter unit 3 for protection. However, as the operation voltage of the overvoltage protective circuit 5 is set taking a surge voltage into consideration, there is a possibility of the overvoltage breakdown of a power device caused by an avalanche drop. Therefore, an IGBT module is composed of an FRD and an IGBT which has a lower breakdown strength than FRD and whose n<->-type layer has a larger thickness to obtain a power module whose heat radiation properties are improved and whose possibility of the breakdown is substantially reduced.

Title: Pulse circuit
Inventor: NITTA SHOZO
IPC: H03K3/033
Filed: 1989-01-20
Abstract: PURPOSE:To clearly and stably set a threshold voltage by providing a voltage comparator, and applying a constant voltage on the inversion input of the comparator. CONSTITUTION:When the level of an input terminal S changes from L to H by an external trigger signal, a gate also goes to H, and a FET 1 is turned on. Thereby, an electric charge accumulated in a capacitor CX is discharged through the FET 1, and potential at a point P is decreased. The potential traverses a voltage value VB set at the inversion input of the voltage comparator COMP from an H side to an L side afterwards. At this time, the output of the comparator drops from VCC to the GND level, and the input of inverters 3 and 4 go to Ls, and the potential of an output terminal Q rises to H. After that, the output of the comparator is inputted to one gate of a logic control part A, then, the FET 1 is turned off. Therefore, the potential at the point P rises gradually by a time constant RXCX, and afterwards, it traverses the voltage value VB from the L side to the H side. At this time, the output of the comparator rises to VCC, and inverter input goes to H, and the potential at the Q goes to L. As a result, a pulse with constant width can be obtained. Since the voltage value VB is set as the threshold voltage in the above constitution, it can be defined uniquely and clearly.

Title: Narrow gap laser beam welding method

IPC: B23K26/082
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To accomplish a narrow gap of joining part by irradiating a filler wire through narrow gap width with supplying a filler wire and executing build up welding from an inner part toward an outer part. SOLUTION: For example, when a thick plate 1 is butt welded, a narrow gap width 7 of a part to be welded is set narrower. A filler wire 9 is inserted into a welding part in the gap 7a. The filler wire part 9 is irradiated with a laser beam from a torch 2 through a gap 7a and a weld metal 4 is formed. Further, while the filler wire 9 is supplied to an irradiating part, a layer is formed with moving the torch 2 in the vertical direction. By repeating this, a multi-layer welding is quickly executed while building up one by one layer. Thus, the gap width 7 is made smaller as a result, welding deformation is turned to smaller, good welding is made possible and cost is reduced as well.
