Title: Laser beam printer
Inventor: SEKIMOTO KENJI
IPC: B41J3/00
Filed: 1987-10-20
Abstract: PURPOSE:To execute stable printing outputting in a wide temperature range by detecting the temperature of a photosensitive drum and executing the compensation of PIDC of light attenuation characteristic of a photosensitive body. CONSTITUTION:The temperature of the photosensitive body 5 is detected by a temperature detector 6 so that optical output to the temperature of a laser oscillator 1 goes to the temperature coefficient of the temperature to relative sensitivity characteristic curve of the PIDC. And the temperature is converted into a voltage and set as the reference voltage source 7c of an automatic optical output control (APC) circuit 7. The output voltage (v) from the reference voltage source 7c is compared with the output voltage (d) obtained by receiving the monitor beam 1c projected from a laser diode 1a by a monitor photodiode 1b and converting it into the voltage in a differential amplification circuit 7b. By inputting the positive and negative compared output voltages P in a laser diode current driving circuit 7a, the driving current of the laser diode 1a of the laser oscillator 1 is set and controlled to compensate the light attenuation characteristic of the photosensitive body 5. Thus, the usage temperature range can be widely secured.

Title: Vibration damping steel material
Inventor: SHOJI SATORU
IPC: B32B15/08
Filed: 1988-10-20
Abstract: PURPOSE:To obtain a vibration damping steel material which has favorable moldability and is durable for use at a high temperature and usable even in the presence of a magnetic field, by a method wherein a grain boundary corrosion layer which has at least a fixed depth is provided on the surface of the steel material and the layer is impregnated with resin. CONSTITUTION:A steel material, which performed grain boundary corrosion treatment up to a depth of at least 20mum from the surface and impregnated with resin, shows extremely favorable vibration damping properties and is, moreover, favorable in moldability, durable for use under high temperature, unnecessary to perform even annealing after processing and usable even in the presence of a magnetic field. At the time of oscillation, since it becomes the maximum generably, although grain boundary corrosion and resin impregnation treatment are effective when they are applied to a surface layer, vibration damping properties are insufficient when its depth is less than 20mum. It is most simple to corrode with an acid solution after precipitation of a carbide into a crystal grain boundary by performing heat treatment as a forming method of a grain boundary corrosion layer on the surface of the steel material. In this instance, when an anode current is added further, the grain boundary corrosion is accelerated. Polyester resin, polypropylene resin, polyethylene resin and silicone resin which have strong viscoelasticity show the highest vibration damping properties as the impregnating resin.

IPC: B41J2/175
Filed: 1993-09-27
Abstract: PURPOSE:To provide an ink jet cartridge which stably supply ink to a head and in which an ink using efficiency for the volume of the cartridge is improved. CONSTITUTION:As ink is consumed from an initial state, ink impregnated with an ink absorbing member 3 in a main ink chamber 2 is first consumed, and a negative pressure is applied to an auxiliary ink chamber 10. It is not changed while this negative pressure is balanced with a capillary force of a first capillary member 11. Further, when consumption of the ink is advanced, negative pressure exceeds the capillary force of the member 11, and the air is introduced into the chamber 10 through the member 11. When the air is once introduced, an entire amount of the ink in the chamber 10 is transferred to the chamber 2, the ink is absorbed by the capillary force of the member 3, the negative pressure is reduced, and an ink pressure is held substantially constant. Since the ink in the chamber 10 is consumed substantially by 100%, its using efficiency is improved.

Abstract: PURPOSE:To carry out Fe-Zn alloying treatment without causing the occurrence of stripped pattern by subjecting a hot dip galvanized steel sheet to heating from the initial temp. of Zn melting up to an alloying holding temp. at a specific temp.-rising velocity by means of high frequency induction heating. CONSTITUTION:A hot dip galvanized steel sheet is passed through a high frequency induction-type heating and holding furnace to undergo heating and subjected to Fe-Zn alloying treatment, by which the corrosion resistance, weldability, painting suitability, etc., of a plated product are improved. In the above treatment, heating is applied at <=50 deg.C/sec temp.-rise rate from the initial temp. of Zn melting of about 410 deg.C up to the alloying and holding temp. of about 550 deg.C.
