Patent JP-S63233455-A (JP)
Title: Microprocessor
Inventor: SATOU YUKISACHI
IPC: G06F15/78
Filed: 1987-03-23
Abstract: PURPOSE:To omit the change of a software in a system and the addition of an external circuit even in the case of connecting the peripheral I/O of slow access and to simplify a constitution by providing a general microprocessor with an external I/O access start/delay block. CONSTITUTION:When an access request (b) to the external peripheral I/O is outputted from an execution block 3 in the microprocessor, an event counter 2 starts counting, counts up its contents only by the value of a delay cycle value setting register 1 and outputs an external access request (c) to an external bus access block 4. Although the execution block 3 outputs a request to the event counter 2 only when external I/O access is required, the block 3 outputs an external memory access request directly to the block 4 based on a direct signal (f) in other cases. Thus, even if external I/O access are continued, the time up to the succeeding I/O access start can be delayed.

Abstract: PURPOSE:To eliminate the necessity for holding a door during the time a person passes through the door by closing the door at a low speed approaching stopping, when the person opens the door detaching his hand from it, and the door closes at a normal speed after the preset short time. CONSTITUTION:When a door is opened, a shaft 8 rotates a gear 7 in the clockwise direction, moving a main piston 6 to the left side compressing a spring 9, and fluid 13 is moved to the right side.

Title: Bar code marking method
Inventor: YAGI HARUMI
IPC: B41M5/26
Filed: 1988-03-18
Abstract: PURPOSE:To make it possible to mark any material with a bar code by applying a sublimable coating material to the surface of a component part, and irradiating the coating material with laser beams to sublime the coating material at only the irradiated parts. CONSTITUTION:A component part 6 is coated with a sublimable coating material 11. The coating 11 may be, for example, an acrylic resin coating material for a white color or an aluminum-containing epoxy resin coating material for a silvery color. The coating material 11 on the component part 6 is scanned, along a plane, with a laser beam emitted from a YAG laser to mark a bar code in the coating material 11. The energy density of the laser beam is so selected as to be sufficient for sublimation of the coating material 11 but not to cause any change in the component part itself. Upon the irradiation, the coating material 11 is completely sublimed at the irradiated parts, leaving the ground of the component part 6 exposed. The laser beam does not cause any change in the ground itself. Therefore, a light flux B from a light-emitting source of a bar code reader is not reflected irregularly, and accurate reading can be achieved.

Title: Method for suppressing width decrease at front end of rolling material in hot rolling
Inventor: TSUKAMURA TAKASHI
IPC: B21B1/26
Filed: 1985-03-29
Abstract: PURPOSE:To control the width decrease of a rolling material without the intricate control of vertical rolling rolls by rolling the rolling material in such a manner that the bulging quantity in the transverse direction by horizontal rolling at the longutudinal end of said material offsets at least part of the narrow width quantity by vertical rolling. CONSTITUTION:The material is subjected to horizontal reverse rolling by the 1st stand 1 and is so rolled that the total sum of the rolling reduction of a forward pass in horizontal reverse rolling is smaller than the total sum of the rolling reduction of a backward pass in the stage of subjecting the rolling material 15 to hot rough rolling by a roughing mill 10 consisting of the 1st stand 11-4th stand 14. More specifically, the spread at the rear end in the longitudinal direction in the stage of the backward pass is larger than the spread at the rear end in the rolling direction. Part of the narrowed width at the top end in the stage when the material is meshed to the vertical rolling rolls 12B-14B of the 2nd-4th stands 12-14 in the mill 10 is thus offset and is thereby suppressed.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a conditional access by recording common information attendant on the programs, together with the program data and using the received latest one of those individual information to the viewers, when the desired programs are selectively reproduced among plural program data which are recorded on a recording medium. SOLUTION: A packet of images and voices of the scrambled information and the common information (ECM) attached to the programs are recorded on a recording medium 20 among plural received program data.

Filed: 1985-04-01
Abstract: PURPOSE:To relieve the load of the worker under working by providing a mobile terminal device receiving/transmitting a non-voice signal in radio with a voice input/output device, using the device in common with a mobile station or using it singly. CONSTITUTION:The worker inputs a commodity code on a commodity accommodating shelf 4 to the voice input/output device 6 via a microphone and a radio mobile station 3 or inputs the code to the voice input/output device 6 by operating manually an operation section 5b of the mobile terminal device 5 (e.g., operation of depression of pushbuttons having the code number). The voice input/output device 6 sends the inputted code to the radio mobile station 3 and a mobile terminal device 5 conversely. Thus, the code is outputted in voice from an earphone. Thus, the code is outputted in voice from the earphone. The worker confirms from the output that the commodity name code is inputted accurately, then the quantity is subject to voice input by the same means and it is outputted in voice similarly. When the input of the commodity name code and quantity is finished, they are displayed on a display section 5c.

Filed: 1980-05-19
Abstract: PURPOSE:To always apply optimum quantity of heat to copying paper without changing the set temp. in a fixing device by performing the conveyance of the paper to a heat fixing part by a driving means separate from a main driving system, and making the conveyance speed thereof variable. CONSTITUTION:The toner is transferred onto copying paper 19, and the paper 19 stripped from a photosensitive drum 10 is attracted onto a conveying belt 24 and is conveyed to a fixing part 25. The belt is driven by a driving means separate from the main driving system so that the conveyance speed of this time equals to the peripheral speed of the drum 10. When the trailing end of the paper 19 spaces from the drum 10 and the paper 19 transfers onto the belt 24, said driving means varies the conveyance speed of the paper 19 via the speed variable means, thereby conveying the paper at the speed at which the quantity of heat it receives it made optimum so that the toner on the paper 19 is fixed well.

Title: Complementary type mos circuit
Inventor: ISOBE MITSUO
IPC: H01L27/092
Filed: 1979-05-31
Abstract: PURPOSE:To lower the threshold voltage of the complementary type MOS circuit without increasing the occupying area thereof by connecting C-MOS inverters in two stages, and connecting N channel elements between the output and input terminals of the second stage and between the drain and the power terminal of the P channel at the first stage. CONSTITUTION:Assuming that the threshold voltages of MOS-FETQ21, Q23, Q25 are VTN, the threshold voltages of MOS-FETQ22, Q24, Q26 are VTP, and the gm are equal with Q21 and Q21 while the gm of the Q26 being sufficiently low. A voltage VDD is applied to the terminal 21, and the terminal 22 is grounded. When the Q26 is truned on or off in response to the L or H level of the terminal 23 to exactly present the same level at the terminal 25, the threshold voltage of the inverter in the first stage is lowered to half of the maximum value of the voltage of the terminal 26, that is, (VDD-VTN)/2. When an intermediate voltage V1 is applied to the input 23, the gate voltage of the Q22 is lowered at the voltage V26 of the terminal 26 to V26-V1- ¦VPT¦. IN this manner the Q25 is disposed to lower the threshold voltage of the circuit without increasing the Q21 so as to diminish the power consumption with respect to the intermediate input voltage.
