Title: Recording device
Inventor: YAMAGISHI YOICHI
IPC: G03B19/02
Filed: 1991-06-17
Abstract: PURPOSE:To completely erase image data recorded in an OTPROM. CONSTITUTION:A system control part 50 reads control data out of the control data area of a connected memory card 28, checks whether or not an information data area is composed of an OTPROM, and sets an OTPROM flag when so. An erasure mode is entered with an erasure mode switch 70 and erasure is carried out in response to the erasure switch 72. When the OTPROM flag is set at the time of the erasure, a specific data pattern is written in the erased data part of the information data area, but when the flag is not set, the control data in the control data area are erased.

Title: D/a converter
Inventor: YAMASHITA MASAAKI
IPC: H03M1/08
Filed: 1994-06-27
Abstract: PURPOSE:To make the foldover noise of a low frequency area small and to reduce the burdens of a low-pass filter by supplementing data corresponding to multiplied clocks between sampled adjacent input digital signals. CONSTITUTION:Sampling clocks inputted to an input terminal 3 are inputted to a data interpolation circuit 7 and a PLL circuit 8. In the PLL circuit 8, timing clocks for which the sampling clocks are multiplied by four are prepared and outputted to the data interpolation circuit 7 and a D/A conversion circuit 1. In the data interpolation circuit 7, digital data to be supplemented between adjacent sampling values sampled by the sampling clocks are prepared. Thus, since the change of the digital code of digital signals inputted to the D/A conversion circuit 1 is made small and the foldover noise of the low frequency area provided in the analog output of the D/A conversion circuit 1 is reduced, the constitution of the low-pass filter of the D/A conversion circuit 1 is simplified and the burdens of the low-pass filter are reduced.

Title: Power saving type communication equipment
Inventor: OKAMOTO MASAHIRO
IPC: H04B1/04
Filed: 1982-08-20
Abstract: PURPOSE:To reduce the power consumption of a communication equipment while securing the continuous communication, by operating at a normal level when the level of transmitting signal is higher than a designated level, then lowering the output level when the transmitting signal level is lower than the designated level. CONSTITUTION:A comparator 10 compares the level of the transmitting signal TS detected by a signal detecting circuit 9 with the reference voltage given from a reference voltage generating circuit 8. When the level of the transmitting signal is high, a control circuit 7 actuates a transmitter 2 with a normal high frequency output level. When the transmitting signal level is lower than the reference voltage, the circuit 7 lowers the high frequency output level of the transmitter 2 by several to several tens decibels to reduce the power consumption of the transmitter 2. The power consumption is further reduced by controlling the output level of the transmitter 2 together with a transmitting low frequency circuit 1.

IPC: B41J2/365
Filed: 1985-07-01
Abstract: PURPOSE:To improve a voltage-impressing method and enhance recording speed, by recording a picture element by impressing a pulse voltage plural times on a thermal head.

Filed: 1990-06-05
Abstract: PURPOSE: To provide a photopolymerizable compsn. showing excellent softness and adhesion property without swelling a developing machine made of polyvinyl chloride in a developing process by incorporating a surfactant into a photopolymerizable compsn. CONSTITUTION: A surfactant is added to each component of a photopolymerizable compsn. such as monomers, oligomers, binders, plasticizer, photoinitiator, polymn. preventing agent and coloring agent.

By using the surfactant in the photopolymerizable compsn., instant adhesion between the photopolymerizable compsn. film and the film base body can be improved. Also adhesion property between the coating film after exposure and the film base body and softness of the film can be maintained in a high level.
