Title: Character convertor
Inventor: TAKAKURA HIROSHI
IPC: G06F17/22
Filed: 1984-03-09
Abstract: PURPOSE:To retrieve indirectly the desired KANJI (Chinese character) by inputting some part of KANJI or the pronunciation of KANJI relating to the desired one at the time of inputting characters which cannot be read by an operator, or has not Japanese reading. CONSTITUTION:The pronunciation which an operator associates is inputted through a keyboard 7. Thus a radical dictionary in a dictionary file 8 is retrieved, and a central processing unit 6 decides KANJI and displays a corresponding character code group on a CRT2. If there is no corresponding character code group, a similarity dictionary in the file 8 is retrieved, and the corresponding character group is displayed on the CRT2. An operator selects the desired character out of the characters displayed on the CRT2. When the corresponding character code cannot be obtained, a conversion failure message is sent to an operator.

Filed: 1988-02-29
Abstract: PURPOSE:To obtain the optimum picture quality adjusting state by providing a means eliminating the noise component of an original signal and a means controlling the limiting level of a limiter circuit section in response to the noise level of the noise component. CONSTITUTION:An input video signal at an input terminal 21 is fed to a delay circuit 22 and also fed to a filter 26 with high pass characteristic.

Title: Controlling method for sheet thickness under condition of roll running at different circumferential speed
Inventor: YASUDA KENICHI
IPC: B21B37/46
Filed: 1979-04-13
Abstract: PURPOSE:To exactly control the sheet thickness without time delay, by detecting the speed difference between upper and lower rolls, by comparing this difference with the reference speed difference, and by controlling the screw position so as to eliminate this deviation obtained from above comparison. CONSTITUTION:At rolling the material 3 by the rolling rolls 1, 2, assume that only the lower roll 2 is driven by the motor 4. The circumferential speeds V1, VD, of upper and lower rolls 1, 2, are detected by the speed meters 5, 6. Since the rolled material's outgoing speed is given by U1=(1+f1)V1=(1+fD)VD, the speed ratio is given by phi=V1/VD=(1+fD)/(1+f1). Since the forward slips f1, fD, are functions of the draft percentage gamma, if the draft percentage gamma changes, the speed ratio phi changes too. Therefore, the ratio phi is operated by the operator 7 and is compared with the set reference speed ratio phi0 by the comparator 8 to obtain the deviation DELTAphi=phi-phi0, which is multiplied by the gain by the operator 9 to give the variation DELTAS of the rolling reduction. The screw down motor 10 is controlled according to this variation DELTAS, and the screw 11 corrects the roll gap so as to make phi=0. As a result, the draft percentage is made always a constant value.

IPC: H04N1/40
Filed: 1985-03-08
Abstract: PURPOSE:To increase the overall processing speed of a system and also to simplify software by performing automatic temperature/pulse width control with a trigger signal given once from the outside and at the same time delivering automatically print signals of the 1st-N-th blocks. CONSTITUTION:The temperature of the heat discharge part of a thermal head is detected by a temperature detecting output terminal 1. Then the signals are converted by a temperature converting circuit 3 and supplied to a pulse width modulation circuit. Then a print command signal is given to a print command input terminal 2 from a control circuit MPU and therefore the pulse width modulation circuit delivers the pulse width signal proportional to the temperature of the thermal head. At the same time, a timer 5 delivers a signal of the pulse width set previously. Then an AND is secured by an AND gate 13 between the output pulse width signal of the pulse width modulation circuit and the output pulse width signal 4 of the timer 5. This AND is delivered for execution of temperature control. At the same time, it is possible to obtain the pulse width signal protected with the maximum rating of the thermal head as the 1st strobe signal. Thus the strobe signals are delivered successively to output terminals 23-27.

Title: Password type locker
Inventor: KAMEI MANABU
IPC: E05B49/00
Filed: 1994-02-18
Abstract: PURPOSE:To enable the cutting of a power source and the conserving of power during the non-use period by storing a number inputted with ten numerical keys into a locker adapted to be locked up or unlocked by a password into an RAM while being written into an electrically erasable and loadable E<2>ROM. CONSTITUTION:A password is inputted from ten numerical keys on a keyboard part of a locker adapted to be locked up or unlocked by a password. A microcomputer part stores the password into an RAM temporarily according to a program stored in a ROM while being shown on a display part and writes it into an electrically erasable and loadable ROM103. When a power source of the microcomputer is switched off at a night or during other non-use period of the locker, the memory of the RAM vanishes. At the start of the application, when the power source is closed, the password stored in E<2>ROM is stored into the RAM again. In the unlocking, a correct password is inputted only. This mechanism enables the conserving of the consumption of power thereby eliminating the need for any measure to counter the power failure.

Filed: 1985-03-05
Abstract: PURPOSE:To control hunting in the number of revolution at the idling of an engine by reducing both the volumes of a surge tank and suction manifold or either volume of them on the basis of the detected idling state of the engine. CONSTITUTION:When an idling switch 11 has detected the idling state of an engine, a control equipment 8 drives an actuator 10, and then control valves 9a, 9b are driven to perform switching action so that a suction flow may be controlled in a suction pipe 2. Each opening of the closed control valves 9a, 9b is set correspondingly to suction air quantity necessary for the idling of the engine. Thus the volume of a surge tank 3 is reduced at the idling of the engine, and hunting in the number of revolution at the idling of the engine is therefore controlled.

Abstract: PURPOSE:To let a backing edge follow a rotary edge in order to improve edge contact, and thereby cut positively machine glazed paper and the like by supporting the backing edge with a regulating machine in such a way as to be freely rocked, and thereby concurrently energizing the backing edge toward the rotary edge side by a spring. CONSTITUTION:When the axial line of a rotary edge 6 is fairly inclined, either of the both sides of a cutting edge 20 of a backing edge 14 is pushed by the rotary edge 6, and the backing edge 14, a holder 15, and a supporting shaft 17 are inclined on the axis of a spring pin 24 along a slot 18 while overcoming the elasticity of a coil spring 19, the cutting edge 20 of the backing edge 14 follows the circular section 7 of the rotary edge 6, that is, the cutting edge 8 of it. In this case, the slippage of the backing edge 14 against the rotary edge 6 is absorbed by the extension and/or contraction in the diameter of a spring 24 engaged with the excess section 21 of the supporting shaft 17 supporting the backing edge 14. By this constitution, edge contact between the rotary edge 6 and the backing edge 14 is improved, machine glazed paper P can thereby be positively cut off by the combined action of the rotary edge 6 and the backing edge 14.
