Title: Recording head, substrate for recording head and ink jet recording device
Inventor: FUJITA KATSURA
IPC: B41J2/05
Filed: 1990-04-11
Abstract: PURPOSE:To obtain a low cost recording head by providing a constitution in which a transistor emitter is electrically connected to an electricity/heat conversion element electrode, and the collector area of the transistor is formed on the surface of a base using a thermal diffusion technique. CONSTITUTION:If a positive potential bias VH1 is applied to an electricity/heat conversion element connected to a common electrode 10 for a collector base of a substrate, a switch G11 is operated to select between groups of electricity/heat conversion elements RH1. At the same time, a switch S1 is operated to apply a selected positive voltage VH1. Then a diode cell SH1 of transistor composition is positively biased, and an electric current runs from an emitter electrodes 11 to cause the electricity/heat conversion element RH1 to generated heat. This results in the transformation of a liquid to bubbles by thermal energy and the subsequent discharge of the liquid from a discharge orifice. Similarly the electricity/heat conversion element RH2 turns a switch S1 and a switch S2 ON selectively and thereby drives a diode cell SH2 to supply an electric current to the electricity/heat conversion element. Consequently, the manhour can be cut down and a recording head at low cost can be obtained without adversely affecting its reliability due to cost reduction.

Title: Air conditioner for car
Inventor: TAKEMOTO KAZUAKI
IPC: B60H1/32
Filed: 1979-07-30
Abstract: PURPOSE:To control the air conditioning in a car room by providing an auxiliary evaporator and the control means of its cooling capability. CONSTITUTION:An auxiliary evaporator 7 and a control circuit which handles each signal are provided. When an air mixing damper 10 is set to the maximum cooling position, a potentiometer 12 indicates the resistivity which corresponds to the maximum cooling. In this case, a solenoid valve 3 turns on by a rear cooler amplifier 20 and the cooling capability of the auxiliary evaporator 7 is maximized. When the air mixing damper 10 is set to 'hot', the potentiometer 12 indicates the resistivity which corresponds to the travel. Its corresponding rear cooler amplifier 20 turns on and off the solenoid valve 3 and the average temperature of the wind blowing from the rear cooler in a car room 18 rises corresponding to the travel of the air mixing damper 10. This reduces the difference in the temperature of air which blows from air outlets 21 and 22. It also improves the temperature distribution of the front and rear seats in the car room 18 and makes the air conditioning space comfortable.
