Title: Ink jet recorder
Inventor: KAWAKAMI KAZUHISA
IPC: B41J2/01
Filed: 1989-01-06
Abstract: PURPOSE:To print a general-purpose recording sheet in high quality by providing a far infrared heater having a specific wavelength for heating and drying ink printed on the recording sheet. CONSTITUTION:When an ink jet recorder for performing a printing operation is operated, a far infrared heater 111 is conducted to be heated to its set temperature in several tens of seconds, thereby irradiating a far infrared ray having a wavelength of 2 - 1,000mum. It is heated with large power at the initial of conduction and then with low power at its set temperature to improve temperature rising characteristic and control its temperature. Ink droplets injected from an ink jet head 101 are adhered to a recording sheet 106 by reciprocating a carriage 103 and conveying the recording sheet 106 by a sheet feed roller 105, thereby forming a character/a line, etc. When a predetermined printing operation is repeated in this manner, the recording sheet 106 is arrived at a position directly under the far infrared heater 111, the ink and the recording sheet 106 are heated, driven by the radiation of the far infrared ray, and then removed from the recorder.

Title: Power-on reset circuit
Inventor: KIKUCHI KOUICHI
IPC: H03K17/22
Filed: 1981-01-09
Abstract: PURPOSE:To achieve a reset output not affected with the rising characteristics of a power supply voltage, by connecting a capacitor to a connecting point of switches in series connection driven complementarily and a switch output, and taking the voltage of a capacitor connected to the output as reset output through detection. CONSTITUTION:A power supply is applied and given to a terminal 1. When the voltage reaches a specified voltage, a clock pulse is generated and this clock pulse turns on switches 6, 7 complementarily. Thus, the terminal voltage of a capacitor 9 is stepwise increased every time the clock pulse is applied. A reset output can be obtained at an output terminal 5 until this voltage exceeds the threshold level of a gate circuit 4.

Title: Memory device
Inventor: KAMATANI MICHITOKU
IPC: G11C17/00
Filed: 1980-01-09
Abstract: PURPOSE:To increase the speed by making the operation margin wider by selecting a sense amplifier of the best characteristics out of plurals of different sense amplifiers. CONSTITUTION:A sense amplifying circuit is composed of depletion type TR-TD1, and enhancement type TRs TE1 and TE2 driven with an input. While TE3 is made on, TE1 and TE2 are operated in parallel and the threshold level of an input level decreases, but while TE3 is turned off, it is determined by TE1 and the threshold level of the input level increases. Therefore, whether the threshold level of the input level increases of decreases depends upon the on-off state of TE3. By releasing terminal K, the ground level is obtained. To decrease the threshold level of the input level by turning TE3 on, a high voltage is applied to K from an outside source to permit polysilicon fuse F to blow out. Thus, the selection of a sense amplifier having a superior input level or characteristics enables to realize high-speed operation.
