Title: Protective device for commutation failure in chopper device
Inventor: KATOU AKIRA
IPC: H02P7/29
Filed: 1977-11-07
Abstract: PURPOSE: To prevent a damping resistance from thermal destruction at a time of commutation failure, by means of detecting an electric quantity, that flows into a supplementary charge circuit, to disconnect the main circuit.  
     CONSTITUTION: When a main thyristor MCRf causes a commutation failure due to a certain reason, a chopper resistor RCH comes to be in a state of short-circuit, and a condenser C will not be charged by the main circuit but by a supplementary charge circuit constituted by a transformer TR, diode bridge DB, and resistor RS. A comparator COM, when a current, flowing into the supplementary charge circuit, exceeds a set value K, will output signal that means a commutation failure in the main thyristor MCRf, to break a circuit breaker HB connected in series to the main circuit.

Title: Core tube member of sheet roll for cleaning
Inventor: ASANO MASAYUKI
IPC: B41F35/06
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To enhance efficiency of a sheet roll for cleaning exchange work by the method wherein a cleaning sheet payed out from a new supply roll becomes fixable by using a take-up tube of a printing machine cylinder cleaning device after the sheet roll for cleaning is used as a supply roll. SOLUTION: A sheet roll for cleaning 26 is picked up by bonding a roll beginning end of a cleaning sheet 24 to a surface of a paper tube 42. Then, an adhesive tape is set on the surface of the paper tube 42. A release paper is applied on the adhesive tape, which prevents application with the cleaning sheet 24 contacted. In using this structure of the sheet roll for cleaning 26 for a cleaning of a printing machine cylinder, firstly the sheet roll for cleaning 26 is used as a supply roll, and after using the sheet roll for cleaning 26, the paper tube 42 is used as a take-up tube. At this time, a tip of the cleaning sheet of a new roll is fixed to the paper tube 42 by the adhesive tape of the paper tube 42. And the paper tube 42 can be destroyed integrally with the cleaning sheet 24 after used so that a work efficiency can be improved.  Then, a splash or an adhesion or the like of a paper powder or a print ink can be avoided by an elimination of an unwind work of the cleaning sheet 24.

Abstract: PURPOSE:To make the read/write operation of a host device in high-speed, by accessing two refresh memories alternately in the picture display time. CONSTITUTION:In the picture display time, even addresses and odd addresses are outputted alternately as refresh memory addresses MA from a CRT controller 12.

Title: Discontinuous sound reaction type audio signal abnormality detector
Inventor: MASUZAKI SEIJI
IPC: H04B17/18
Filed: 1989-05-26
Abstract: PURPOSE:To prevent malfunction even at the time of input of an audio signal exceeding a rated level in a broadcasting machine system having amplifiers by adding a masking circuit which excludes an influence of response characteristics of limiting amplifiers. CONSTITUTION:When the audio signal exceeds the rated level, reference input- side signals 1 and 2 rectified, smoothed, and amplified by rectifying/smoothing/ amplifying circuits are inputted to a masking circuit 12 and are outputted as a reset signal to the reset terminal of a flip flop circuit. Since the reset signal is inputted to the flip flop circuit at this time, masking is so performed that it is not detected as abnormality that the audio signal exceeds the rated level, and an influence of response characteristics of limiting amplifiers is excluded. Thus, the malfunction is prevented even at the time of input of the audio signal exceeding the rated level in the broadcast machine system having limiting amplifiers.

IPC: G11B20/06
Filed: 1985-06-21
Abstract: PURPOSE:To simplify the constitution of an indicator driving circuit by constituting the title circuit to extract an AGC detection output voltage out of an AGC circuit by a current mirror, and using the result as a tracking indicator driving voltage. CONSTITUTION:An AGC detection output voltage 400 increases slightly in the operation of th tracking indicator driving circuit, but is held almost constant (V1). A control current 500, on the other hand, is zero when a necessary controlled variable is at a fine level and increases in a control state according to said gain controlled variable. For the purpose, variation in the detection output voltage 400 is converted by a transistor (TR) 4 into a current, whose variation is converted by a resistance 8 into variation in voltage, thereby obtaining specific voltage variation characteristics. This voltage variation is used as the indicator driving output 200, and then a precise tracking indicator driving voltage which is discriminated excellently is obtained almost at the standard input level of an input FM audio signal 100, simplifying the constitution of the circuit.
