Title: Stress added shot peening method for steel wire and device therefor
Inventor: SASAKI MASAJI
IPC: B24C1/10
Filed: 1994-04-01
Abstract: PURPOSE:To adjust residual stress on a surface of a steel wire efficiently by conducting shot peening treatment while giving torsion having specific torsional stress to a section of the steel wire which is drawn between sections of the steel wire of a predetermined length. CONSTITUTION:When a steel wire 1 after it is drawn into an extremely fine wire undergoes the shot peening treatment, the steel wire 1 is bent into the shape of loop by a brake device 3 and a roller for loop 2 before the steel wire 1 is wound into a winding device 4, and the bend radius is controlled to add required bending stress so that the shot peening treatment is done for a part which is bent. That is, shot peening is done while giving torsion to a section of the steel wire between the sections of the steel wire having a predetermined length and adding torsional stress so that the amount of torsion is 1=100d (1 is torsional length, d is wire diameter) from an axis in the longitudinal direction of the steel wire and an angle in the range of 1-90 deg.. Or, shot peening is done while giving bend due to deflection to a section between sections having a predetermined length of the steel wire and adding bending stress so that the bend radius becomes r<=500d.

Title: Aligning method for mounting electronic device onto circuit board
Inventor: WAKIHARA YOSHINORI
IPC: H01L21/60
Filed: 1994-04-01
Abstract: PURPOSE:To correct the positional shift between a bump and a pad easily when a semiconductor chip having a mounting face provided with bumps or an electronic device, e.g. a semiconductor mounting device, is aligned with a circuit board. CONSTITUTION:A bump 2 formed on the mounting face of a BGA(Ball Grid Array) is observed by means of a first camera 6 and then the BGA 1 is shifted from the observing position. Subsequently, a mounting pad on a printed wiring board is observed by means of a second camera disposed while aligning the optical axis with that of the first camera 6. A computer then operates the coordinates of the bump and the corresponding mounting pad based on the image data observed by means of the first and second cameras. The printed wiring board is shifted according to the operation results thus correcting the positional shift between the bump 2 and the mounting pad.

Abstract: PURPOSE:To keep the linearity of an input signal and an output signal over the broad range of the level of the input signal by constituting to draw a current following the change of the input signal approximately from the connecting point of the emitter of an NPN transistor and the base of a PNP transistor. CONSTITUTION:In a correcting current generating circuit 16, since the current of a constant current source 20 becomes the sum of an Il1, the emitter current of a second NPN transistor 17 and a base current which flows from a second PNP transistor 18 into the constant current source 20, when an input signal Vin is large, that is, the base voltage of the second NPN transistor 17 is low, an emitter voltage, consequently, the emitter voltage of the second PNP transistor 18 becomes low and the current to flow in a second resistance 19 becomes large. Consequently, a correcting current I2, that is, the collector current of the second PNP transistor 18 increases to that extent. Conversely, when the input voltage signal Vin is small, the current to flow in the second resistance 19 becomes small and the correcting current I2 decreases to that extent.

Title: Unloading valve
Inventor: SHIRAI KIYOSHI
IPC: F15B11/00
Filed: 1993-03-25
Abstract: PURPOSE:To switchover a main valve, which opens and closes ports of both a pump and a tank, slowly from unload to on-load by opening the main valve by virtue of pump port pressure, closing it by virtue of a main spring and the pressure inside a back pressure chamber and communicating the back pressure chamber to a load pressure introduction passage through an orifice. CONSTITUTION:A main valve 60 is held in the position where a pump port 62 and a tank port 63 are closed by means of a main spring 61. Pressure oil is supplied to an actuator by switching over an operating valve from the condition of the operating valve in a neutral position, the main valve 60 in an opened position (unload condition) and discharging pressure oil of an hydraulic pump in an unload condition. Load pressure inside the load introduction passage raises and flows into a back pressure chamber 64 for the unloading valve but load pressure flows into the back pressure chamber 64 through a small hole 65. Therefore, pressure oil raising inside the back pressure chamber 64 becomes slow and the main valve 60 is pushed slowly to the closing position (on-load condition). Thus pressure oil flow to the actuator does not increase suddenly and the actuator operates smoothly.

Abstract: PURPOSE: To prevent stall in starting of an engine by providing a starting controller for switching the capacity control mechanism of a compressor to a partial load state in starting of the engine and switching it to a full load state when the complete combustion of the engine is detected. CONSTITUTION: The capacity control mechanism 2A of a compressor 2 is controlled in accordance with a command from a starting controller 22 and signals, are input to the starting controller 22, which are output from a complete combustion detecting means 23 for detecting the complete combustion of an engine 1 and an engine controller 20.
