Patent JP-H03156877-A (JP)
Title: High-frequency heating device
Inventor: HISHIYAMA KOJI
IPC: H05B6/66
Filed: 1989-11-15
Abstract: PURPOSE:To efficiently feed electric power and reduce current capacity at a low cost by connecting an inductor between a double-voltage rectifying circuit and a magnetron fed with electric power. CONSTITUTION:The commercial power 1 is rectified and converted into smooth DC power by a rectifying/smoothing circuit 2, and it is boosted by a transformer 3 and applied to a semiconductor switch 5. When positive voltage is applied across the base and emitter of the element 5, the element 5 is turned on, and the high voltage of the transformer 3 drives a magnetron 9 via a magnetron driving circuit 8 serving as a half-wave double-voltage circuit constituted of a capacitor 20 and a diode 21. When negative voltage is applied, the element 5 is turned off, and the electromagnetic energy stored in the exciting circuit of the transformer 3 is discharged into a snubber circuit 4. When an inductor 29 is connected between the circuit 8 and the magnetron 9, electric power can be stably fed to the magnetron 9. The emergency surge current can be smoothed, thus a small-sized and inexpensive device with a low current capacity is obtained.

Title: Semiconductor integrated circuit device and manufacture thereof
Inventor: OTAKE SEIJI
IPC: H01L21/8249
Filed: 1993-11-26
Abstract: PURPOSE:To reduce the series resistance of a current path by also forming a P-type region having high concentration formed for the inter-element of an N-P-N bipolar transistor to a vertical DRAW transistor section and utilizing the P-type region as the on current path of the vertical DMOS transistor. CONSTITUTION:Control voltage is applied to a gate electrode 9 to turn a DMOS transistor 1 on. Consequently, on curents are made to flow through a path reaching an electrode 14 through N-type body regions 7, a P-type well region 6, a P-type buried region 5 and a P-type connecting region 12 from P-type source-drain regions 10. Accordingly, the P-type well region 6 of the path of on currents is replaced with the P-type connecting region 12 having concentration higher than the region 6 as compared to conventional devices, thus generally lowering the series resistance of the DMOS transistor 1.

Title: Recording or reproducing device
Inventor: OKINO TADASHI
IPC: G11B21/10
Filed: 1986-12-15
Abstract: PURPOSE:To suppress a malfunction in reading and writing to a recording medium by moving a head to a predetermined position or a detected non- recorded position when the detected output of an oscillation and a shock applied to the head is larger than a threshold. CONSTITUTION:The output proportional to the strength of the oscillation and the shock applied to the head during a reproduction processing is inputted to a control circuit 7 from acceleration sensors 4-6. When the input is stronger than a predetermined level (decision level 2) and the position of the head may be remarkably dislocated as the number of frames is changed, the circuit 7 returns the head 11 to a reference position through a head driver 12 to initialize. Immediately before the oscillation and the shock are applied, the head 11 is returned to execute a track finding. At the time of recording, when the decision level is above 2, the head 11 is returned to the reference position once. Then, the frame is advanced to one before the number of the frames to be recorded immediately before the oscillation and the shock are applied. Then, after the track finding is executed, one frame is again advanced to reset to an optimum position for recording.

Filed: 1993-11-26
Abstract: PURPOSE:To increase the program executing speed without using a shadow register set in regard of method that boosts a given instruction string and simultaneously carries out the instructions in each number of them set in parallel to each other. CONSTITUTION:A branching instruction and an instruction which decides the instruction branching conditions are retrieved out of a given instruction string, and e moving instruction range is decided (100). It is decided whether or not the branching conditions are satisfied and a branching flag F is set to the value corresponding to the deciding result of the branching conditions by a branching deciding instruction. This instruction is set at the head position and at the same time the executing instruction is moved to an idle field in the decided range when the branching conditions of the branching instruction is satisfied end not satisfied respectively. At the same time, the value B showing the conditional branching direction is inserted for one or both of instructions (102). The pairs of instructions are fetched for each processing from the instruction string where the movement of the instruction is completed, and the instructions are simultaneously carried out. At the same time, one of paired instructions that should not be carried out due to the combination value of the flag F and the value B is invalidated (200).
