Patent JP-S5711529-A (JP)
Title: Semiconductor device
Inventor: NISHIZAWA HIROSHI
IPC: H03K5/00
Filed: 1980-06-25
Abstract: PURPOSE:To achieve a semiconductor device generating clocks of an arbitrary period, by using two transistors (TRs) and two capacitors and changing the combination of the capacitors. CONSTITUTION:When a clock phiCP' changes from ''L'' to ''H'' at time t1, a node N1 is lifted to ''H'' with a capacitive coupling of CT of a capacitor 1. Thus, a Q2 turns on and the level of the N1 is increased. Next, when the phicp' changes from ''H'' to ''L'' at time t2, the level of N1 is made negative with the capacitance coupling by the CT of the capacitor 1. Thus, the Q1 turns on and the level of N1 returns to the threshold voltage -VTH of the Q1. The same cycles are repeated and the level of N2 is gradually increased, and when this exceeds the threshold voltage VTH of the Q3, the Q3 turns on and the circuit is operated. Through the operation of the circuit 8, a Q4 turns on and the potential of N2 returns to ground. Thereafter, the same cycles are repeated. Thus, by selecting the capacitance of the capacitors 1,4 suitably, a clock generator having an arbitrary period can be achieved.

Title: Method and device for recycling recording medium
Inventor: TOMONO HARUO
IPC: B41J29/26
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To remove a recording agent regardless of the kind of the recording agent and to recycle a recording medium by jetting a blast material to a recording layer. SOLUTION: By spraying the blast material 4 with compressed air to the surface of the already recorded recording medium where the recording layer 2 has been already recorded by the recording agent such as toner or ink on the surface of the recording medium 1 such as paper or synthetic resin film by a blast jetting device 3, the recording layer 2 on the surface is ruptured and removed. Any system such as a direct pressure system in which the blast material is jetted by pressuring the inside of the device or a gravity system in which the blast material is made to drop and sprayed may be used as the blast device. Then, it does not matter whether it is a wet type or a dry type but it is desirable to use a direct pressure system dry type blast device from the viewpoint of operation efficiency.  Any material such as sand, metallic particles, glass particles, ceramic particles, thermoplastic resin particles such an nylon, or thermosetting resin particles such as melamine resin, phenolic resin, alkyd resin or urea resin can be applied as the material for the blast material.

Title: Control method of idling rotation number of internal-combustion engine
Inventor: KOBAYASHI KOUICHI
IPC: F02D41/20
Filed: 1983-05-17
Abstract: PURPOSE:To maintain an idling drive characteristics of an engine at a constant level by driving an actuator in accordance with a corrected time of electrication corrected with a correction coefficient based on a fixed data and an actual voltage. CONSTITUTION:When making an engine rotation number close to a target idling rotation number, a deviation of the target idling number and an actual idling number is computed at a step 101. A time of electrification with a fixed battery voltage based on this deviation is computed at a step 102. At a step 103, an actual battery voltage is corrected by a correction coefficient based on the data decided by a difference between an actual battery voltage and the said-fixed battery voltage. An actuator is driven in accordance with the corrected time of electrification and the actual battery voltage at a step 104. This construction permits an idling drive characteristic of the engine to keep a constant level without being influenced by a change of battery voltage.

Title: Device and method of magnetic reproduction
Inventor: SAITO ISAO
IPC: G11B15/473
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To absorb the error due to the secular change or temperature variation and to stabilize the PLL operation by securing the operating range of PLL similarly to the time of normal reproduction even at the time of high speed running such as in the FF/REW mode, etc., and measuring again the sensitivity just before the high speed running. SOLUTION: When the information of tape speed is given to a reference value producing part 35 at the time of FF mode or REW mode, the reference period to be given to a comparison part 33 is changed by the producing part 35 in accordance with the information of tape speed. By this operation, the relative speed between a magnetic tape and a magnetic head at the time of high speed reproduction becomes also the same as that at the recording time. At the time of high speed reproduction, the correction amount such as a free run frequency of a VCO 21, i.e., oscillation frequency when the input error voltage is a center value, is made to change in accordance with an azimuth angle, is calculated for each of odd number channel and even number channel by a correction amount calculating part 4 then outputted to give it to the VCO 21 through a D/A converter 5.
