Title: Method for detecting output current of inverter
Inventor: KUDO MASAKAZU
IPC: H02P27/08
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To measure the voltage corresponding to two phases of short turning- off time of the lower arm semiconductor opening/closing element driving signal of a main circuit with high accuracy by A/D-converting the voltages in accordance with the electrical angle of an output voltage command to an inverter. SOLUTION: A three-phase analog current detecting circuit 6 performs current-voltage conversion on the output current of an inverter being operated and an MPU 7 successively selects two phases having short turning-off time of a command given to a power device controller 4 in accordance with the electrical angle of an output voltage command to the inverter and A/D-converts the phases. The analog output voltages of the two phases become voltages following analog current flowing to an insulated gate bipolar transistor(IGBT) Q2 (Q4, Q6) and free wheel diodes D2 (D4, D6) and the output current of the inverter is detected by A/D-converting the analog voltage. Therefore, the output current of the inverter can be detected with high accuracy even when a twoarm modulation system having two modulating arms is used.

Filed: 1985-10-14
Abstract: PURPOSE:To improve the strength of a wet film in a developing soln. by forming a hydrophilic colloidal layer contg. gelatin contg. >=12wt% high mol. wt. component. CONSTITUTION:When a silver halide photographic sensitive material having at least one hydrophilic colloidal layer on the support is produced, gelatin contg. >=12wt% high mol. wt. component is used in the hydrophilic colloidal layer. The proportion of the high mol. wt. component to the gelatin is obtd. by calculating the proportion of the peak area of the exclusion limit to the whole area. In a concrete way, a line perpendicular to a horizontal axis is drawn from the minimum point of a GPC curve appearing at about 25min retention time, and the proportion of the area of the part on the left of the line to the whole area is calculated. The hydrophilic colloidal layer is a photographic emulsion layer, a protective layer, an intermediate layer, an underlayer, a back layer or other layer contg. hydrophilic colloid, that is, gelatin. Thus, the strength of a wet film is a developing soln. or the like is improved without changing the swelling rate.

Title: Thrust ball bearing
Inventor: SATODA MASAHIKO
IPC: F16C33/58
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a structure which can absorb the positional slippage between mutual races. SOLUTION: The groove curvature (radius of curvature) Ra of the receway surface 4a1 of a race 4a on a turning side is larger than the groove curvature (radius of curvature) of the receway surface 4b1 of a race 4b on a stationery side. In the case where a positional slippage α is caused by an attaching error between the races 4a, 4b, the positional slippage is absorbed by the race 4a being larger in the groove curvature of the raceway surface 4a1. On the other side, positional relation between the race 4b being small in the groove curvature of the raceway surface 4b1 and a ball 4c does not change, and the ball 4c is restricted on the raceway surface 4b1.

Title: Layout structure for electrostatic protected circuit
Inventor: MISAWA HIDENOBU
IPC: H01L27/06
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To set a gate electronic of an electrostatic protection transistor in a stable floating state to allow its easy shift to its snap-back state at the time of static electricity application, and when there is mixture of a transistor which is easily shifted to the snap-back state and a transistor which is hardly shifted thereto, to alternately arrange these transistors to improve its break-down voltage.

A layout of the transistor section 2 is designed to suppress flow-in and flow-out of electrostatic charges, thus realizing a stable floating state, even at the time of static electricity application and facilitating its snap-back. When a mixture of electrostatic protection transistors which are different in the easiness in shifting to the snap-back state exist, the transistors are alternately arranged to lighten a load of the transistor having the hard to snap-back shift for improving its break-down voltage.

IPC: G01D5/244
Filed: 1991-08-14
Abstract: PURPOSE:To make always constant the width of rectangular pulses included in the reference signal in an optical type encoder. CONSTITUTION:An encoder is equipped with a light source 1 and a displacement member 2 where a pair of reference slits 21, 22 separated from each other in the displacement direction, as specified so as to intersect the light source 1, are formed in the reference positions specified.

Title: Clip for long article
Inventor: OTA NORIHIDE
IPC: F16B5/12
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To certainly keep a state engaging with an attaching hole by controlling the oscillation of a clip. SOLUTION: The extending direction of a pair of pawls 14 is set up to exist within a flat plane formed of the longitudinal direction of a head part 10 and the extending direction of a leg part 13. When a clip oscillates vertically relation to the longitudinal direction of the head part, a pair of pawls 14 engages with an attaching hole and therefore moves in the direction where their mutual interval becomes narrower. Thus since the pawl part is moved in the direction where elastic force is more stored, the oscillation of the clip is controlled.
