Title: Thermal head
Inventor: KOZAI FUMIO
IPC: B41J2/345
Filed: 1987-12-09
Abstract: PURPOSE:To reduce the amount of heat that is absorbed by independent electrodes, as well as to realize the uniform temperature increase in individual dots so as to prevent adjacent dots from being influenced by the temperature increase by constructing independent electrodes such that they become thinner than a common electrode. CONSTITUTION:Independent electrodes 11 are constructed such that they become thinner than a common electrode 2. When a switching circuit 6 is closed, current (i) is allowed to flow from the common electrode 2 to the independent electrodes 11 via a resistance unit 1, and the resistance unit 1 is heated. The temperature of the resistance unit 1 quickly increases. Little heat is permitted to be transferred from the independent electrodes 11 to the ceramic substrate 4, and the uniform heating and temperature increase can be realized throughout a whole heating area. The heat transfer from the resistance unit 1 to adjacent dots is reduced when heat is permitted to be transferred from the common electrode 2 to the ceramic substrate 4, and the temperature increase in adjacent dots is thereby prevented. In addition, the uniform quality of setting is accomplished, and the adjacent dots can be prevented from being influenced by the temperature increase.

Patent JP-H01150752-A (JP)
Title: Refrigerator
Inventor: ABE TOSHIRO
IPC: F25B1/04
Filed: 1987-12-08
Abstract: PURPOSE: To avoid the damage due to the liq. compression at the starting of a scroll compressor by opening a normally closed valve provided in a fixed scroll-side intermediate compression chamber by the internal pressure in this compression chamber in the case of stating of the scroll compressor to escape a liq. refrigerant to a refrigerant piping at the upstream of a throttle unit. CONSTITUTION: In case a scroll compressor 1 starts with a liq. refrigerant stagnating in a compression chamber 12, the refrigerant is compressed to bring about an abnormally high pressure in an intermediate compression chamber 12b having a closed structure. When the pressure in this chamber 12b becomes higher than the sum of a force of valve retaining spring 16b for retaining a valve element 16a and pressure in a refrigerant piping 17, a normally closed valve 16 opens. The refrigerant in the intermediate compression chamber 12b flows because of the pressure difference from an opening 15 via the piping 17, joins in a refrigerant piping 6a connecting a condenser 2 to a throttle unit 3 to an evaporator 4 and flows to the throttle unit 3.  Thereby the pressure in the intermediate compression chamber 12b never exceeds a limit pressure, hence no excessive force is exerted on a bearing, etc., of the scroll compressor 1 and this compressor smoothly starts, without being damaged.
