Title: Engine acceleration correction device
Inventor: NISHIMORI TAKAYOSHI
IPC: F02D41/04
Filed: 1983-08-05
Abstract: PURPOSE:To make acceleration correction possible without response time-lag of an engine which uses a fuel supply quantity correction means at the acceleration, by determining the time to begin corrected fuel supply from the variation of the opening of a throttle valve and also the time to finish corrected fuel supply from the change of suction negative pressure. CONSTITUTION:During the operation of an engine 1, a control unit 16 accepts the output of a throttle valve opening sensor 13 and a negative pressure sensor 12 and judges the need of acceleration by checking if the difference of the throttle valve opening at present and at the previous time is more than a criterion. When the need of acceleration is decided, the necessary acceleration is obtained from the variation of the throttle valve opening, and a temporary pulse (fuel quantity to be corrected) corresponding to the rotational speed of the engine and the necessary acceleration is read out to make ashychronous injection. After this, a counter does a down count to measure the time TA corresponding to the time-lag of the negative sensor system, and when the time TA is elapsed, the difference of the suction negative pressure at present and at the previous time and an acceleration completion criterion are compared to check the acceleration completion, and when the acceleration completion is decided the ashynchronous injection is finished.

Title: System for reproducing vertical magnetization
Inventor: SASAKI KIYOSHI
IPC: G11B5/02
Filed: 1984-07-13
Abstract: PURPOSE:To obtain a stable output by detecting a low frequency component of an output of an MR element and using its output to control a current flowing to a conductor thereby eliminating fluctuation of the operating point of the MR element. CONSTITUTION:An output of a broad band filter 16 is a reproduced output of a head in the constitution comprising a non-inverting reproducing amplifier 15, the broad band amplifier 16, an integration device 17 and a current amplifier 18. If the operating point of the MR element is moved, it is detected as a fluctuation of a low frequency signal at an output of the reproducing amplifier and then the output of the intergration device 17 represents the fluctuation of the operating point. As a result, a reproducing signal obtained as the output of the broad band filter 16 is a stable signal. Thus, in reproducing a vertically magnetized signal from a vertical two-layer medium, the reproducing signal with less fluctuation in the operation, i.e., less output fluctuation is obtained.

Abstract: PURPOSE:To avoid a sheet from re-skewing by a registration roller by providing a gate at the rear of the registration roller, thereby to remove skewing of a sheet while the registration roller is retreated. CONSTITUTION:The leading end of a sheet 2 transported by a feed roller 1 passes between a registration roller 3 retained at a retreat position by retreating means and a pinch roller 3a and reaches a gate 4. The skewing of the sheet 2 is removed by bringing the leading end of the sheet 2 into contact with a click member 4b of the gate 4.

Simultaneously, the gate 4 is rotated to release the engagement of the click member 4b with the sheet 2. Subsequently, the registration roller 3 is rotated to transport the sheet 2 in a designated timing to a recording portion (e.g. photoreceptor) without re-skewing.

Abstract: PURPOSE:To correct the skew of the sheet in the condition where a sheet is held between a pair of resist rollers by providing a rotating means which turns a carrying means according to the inclination amount of a member to be transferred detected by a detecting means and corrects the inclination of the member to be transferred. CONSTITUTION:When the leading edge of the paper P is detected by a paper position sensor 52 after the leading edge of a paper P is detected by a paper position sensor 51, a distance delta can be recognized from drive pulse number of a pulse motor 58 after detecting the edge by the paper position sensor 51 until detecting the edge by the paper position sensor 52. The mutual distance (l) between the paper position sensors 51 and 52 is constant so that the inclina tion theta of the paper can be determined from the distance (l) and the drive pulse number. When the inclination theta of the paper is determined, the pulse motor 65 is driven according to the inclination theta. Consequently, the resist rolls 17 are turned in the direction for correcting skew of the paper P. Therefore, skew can be corrected by the resist rolls 17 with pinching the paper.

Title: Apparatus for producing metallic sheet
Inventor: MIHARA YUTAKA
IPC: B21B1/46
Filed: 1988-06-13
Abstract: PURPOSE:To provide the apparatus for production which prevents the generation of edge cracks and yields the metallic sheet with good productivity by providing a pair of guide plates which are inserted on one end side between rolling rolls and extend on the other end side up to the metal particle falling part on a substrate between a rolling mill for a deposit and the substrate. CONSTITUTION:While the high-temp. metal particle (m) solidify rapidly, the metal particles fall and integrate onto the substrate 5, thus forming the plate- shaped deposit D. The deposit D is continuously drawn out of the rotating substrate 5 and while both side ends are guided by the guide plates 8, the deposit is introduced into the rolling mill 2 and is rolled. The wall thickness at both side ends of the deposit D is, therefore, sufficiently assured and the temp. drop thereof is suppressed. In addition, the generation of tensile stress in the deposit D is suppressed as said deposit is restrained by the guide plates 8 and is rolled and, therefore, the generation of the edge cracks is adequately prevented. The metal sheet S after the rolling is coiled by a coiler 14.

Title: Information processor
Inventor: ENDOU KAZUHIRO
IPC: G06F21/79
Filed: 1981-09-14
Abstract: PURPOSE:To improve the secrecy of the memory contents, by comparing the contents corresponding to the supplied address with the contents of a cipher code and reading the memory only when the coincidence is obtained from the comparison. CONSTITUTION:The contents of an address fed from outside are set to a register 2 via an address buffer 4. In this case a cipher code is read out of a cipher code cell 8, and the contents of the register 2 are compared with the contents of the cipher code. When the coincidence is obtained from the above-mentioned comparison, a memory cell 7 is read. While an address clamping circuit 5 is set if no coincidence is obtained from the comparison. Thus the address signal fed from the buffer 4 is changed for its address code and then delivered. Therefore the cell 7 receives an access by an address having no relation with the normal address. Thus it is impossible to decode the contents of a memory, and the secrecy is improved for the memory contents.
