Patent JP-H01318118-A (JP)
Title: Instruction canceling system
Inventor: SHIMAKURA KAZUKO
IPC: G06F9/38
Filed: 1988-06-18
Abstract: PURPOSE:To reduce the overhead of a CPU and to rapidly cancel an instruction by canceling a specific instruction without reissuing an instruction once generated and stored in a stack buffer. CONSTITUTION:Out of instructions generated from a CPUa, only the instructions to be stored in a RAM 4 to be a stack buffer is prefetched, stored, successively extracted, and then executed. The instruction once generated and stored in the RAM 4 can be canceled by specifying the ID of the instruction to be canceled without regenerating the instruction. When the CPUa is to cancel the stacking RAM 4, the ID allocated to the cancel instruction is sent to a CM adaptor (c) together with the cancel instruction. When the sent instruction is a cancel instruction, a processor 1 obtains an address in the RAM 4 storing the instruction to be canceled from a correspondence table 2 based upon the ID and erases the corresponding ID in the table 2 and the address.

Title: Tape residual quantity calculating method
Inventor: DESAKI YOSHITO
IPC: G11B27/17
Filed: 1989-06-14
Abstract: PURPOSE:To accurately recognize the residual quantity of a tape and to prevent the tape and equipment damaged when feeding the tape at high speed by performing a specific arithmetic operation by using a reel rotation ratio. CONSTITUTION:A value R with respect to the total quantity of the tape is found in advance from rotating speed n3 when no slippage of a timer roller 3 occurs in an operation, the rotating speed n1 and n2 of a reel, and the radii R1 and R2 of the reel when the tape is wound based on equation I. Thereby, the reel rotation ratio k=n2/n1 can be measured, and the radii R1 and R2 can be found regardless of the timer roller 3 by using equation II. Therefore, it is possible to accurately recognize the residual quantity of the tape from time to time without impairing the tape and the equipment even when the tape is fed at high speed, which expands the range of fast tape feed.

Title: Image recorder
Inventor: CHIKARAISHI YUJI
IPC: G02B27/00
Filed: 1987-06-18
Abstract: PURPOSE:To obtain a distinct image which does not have any flare due to scattered light by exposing a photosensitive material to an image by using a light emitting element embedded in a transparent body and covering the outer periphery of the transparent body with a light shielding material and limiting an optical path. CONSTITUTION:This is an image recorder which exposes the photosensitive material to the image by using the light emitting element 78 embedded in the transparent body and the outer periphery of the transparent body is covered with the light shielding material 83 to limit the optical path. Light from the light emitting element 78 passes through only the limited optical path which is not covered with the transparent body to reach an optical system and this effective beam is accurately image-formed through the optical system. The light from the light emitting element which impinges on the part covered with the light shield material can not exit to the outside, so the light never reaches the optical system indirectly and no flare is generated.

Title: Sense amplifier of nonvolatile semiconductor memory device
Inventor: KIN MEISAI
IPC: G11C16/06
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To obtain a sense amplifier for a volatile semiconductor memory device of a folded bit line structure which can sense without being influenced by the loading of a bit line connected to a memory cell. SOLUTION: This sense amplifier is provided with a bit line insulation part 12 located between bit lines BLi, BLj connected to a memory cell array 100 and, sub bit lines SMLi, SBLj connected to an input/output gate circuit. An insulation control signal ISO is applied to the bit line insulation part. A voltage control current source 13 of a latch form which consists of N-channel MOS transistors Q21, Q22 is coupled to the sub bit lines. A switching part 14 is coupled between the voltage control current source and a signal line. Since the insulation control signal is brought into a non-activation state during a sensing operation, the bit lines are completely insulated from the sense amplifier by the sensing operation. The sensing operation is not influenced by the loading of bit lines at all. Accordingly, a sensing speed is improved and a peak current is reduced.

Abstract: PURPOSE:To reduce the fluctuation of the flow rate on the downstream side of a TSA adsorbing tower and to make the flow rate and pressure of purified air constant by preliminarily increasing the inlet flow rate of the TSA adsorbing tower corresponding to the change-over time of the TSA adsorbing tower before the TSA adsorbing tower enters a pressurizing process. CONSTITUTION:The inlet guide blade 11 of an air compressor 12 is preliminarily operated by a control unit 12 a definite time before a TSA adsorbing tower 2 enters a pressurizing process at the time of the completion of a cooling process and the air compressor 1 is subjected to incremental operation. Next, the TSA adsorbing tower 2 enters the pressurizing process and a part of purified air is sent to the TSA adsorbing tower 2 through a pressure gas inlet change- over valve 10. Whereupon, the purified air is increased in quantity to be capable of being sent out in the same amount as the purified air before pressurization. By this constitution, the flow rate of the purified gas of the TSA adsorbing tower is always kept constant and the pressure of purified gas is kept almost constant to always perform stable operation.
