Title: Guide mechanism for optical head
Inventor: FUJISAWA SHUJI
IPC: G11B7/085
Filed: 1985-08-28
Abstract: PURPOSE:To reduce the weight of a guide mechanism for optical head and also to eliminate the play produced between a bearing part and a guide shaft, by using the plastic to form a bearing block which supports the optical head and at the same time forming an elastic projection in a body with the bearing part of the bearing block. CONSTITUTION:A bearing block forming a guide mechanism for optical head is made of plastic and two opposite bearing parts 12 and 13 are formed together with through holes respectively. Then a guide shaft 14 is put slidably into both through holes of the parts 12 and 13. The elastic circular projections 30 and 31 are formed near the edge parts of both through holes for the shaft 14 unitedly with the end faces of both parts 12 and 13. These projections 30 and 31 generate the elastic force to the entire surface of the shaft 14 in the direction toward the center axial line of the shaft 14 when the shaft 14 is put through both through holes since the plastic projections 30 and 31 have the elastic force. As a result, the shaft 14 is supported elastically and therefore the play can be avoided between the inner walls of both through holes and the shaft 14.

Title: Mathod and device for heat exchange
Inventor: KUSUSE MIKIO
IPC: F24H9/00
Filed: 1983-10-11
Abstract: PURPOSE:To prevent detrimental components within a waste gas from condensing and adhering to heat exchange surfaces thereby to improve the durability of a heat exchanger by circulating air as a heat medium between a waste gas system and a hot water system to control the temperature of circulated air at the inlet of a gas-gas heat exchanger within the waste gas system. CONSTITUTION:When a control panel 9 is manipulated to rotate a blower 10, air as a heat medium circulates within an air duct 5 as indicated by arrows D and E, and absorbs the calory within the waste gas in the gas-gas heat exchanger 4 of a waste gas system G. Thus, the temperature of air becomes high, and the heat is radiated in a water heat exchanger 2 of a hot water system W to convert cold water into hot water. In this case, the temperature of waste gas at the outlet 4a of the gas-gas heat exchanger 4 is constantly detected by a temperature detector 6. Thus, when the temperature of the waste gas is decreased to a temperature which is less than the condensation temperature of the detrimental components a damper 11 opens a bypass 5c under the command from the control panel 9, and air having a temperature which is greater than the condensation temperature of the detrimental components flows through the inlet 4b into the gas-gas heat exchanger 4.

Filed: 1981-11-25
Abstract: PURPOSE:To allow the titled device to be obtained with low cost and high reliability, by forming a structure wherein neither a hollow part nor the upper layer of some layer is formed partially. CONSTITUTION:An IC22 is formed on a substrate Si 21. Particularly, the part of the circuit 22 has high generation of heat and is contrived for the efficiency of heat radiation without forming a semiconductor layer in the upper layer. The  second layer 23, third layer 24 and forth layer 25 are respectively IC, only the  fifth layer 26 is assembled by a phase-down bonding, and therefore the layer 26  is formed also in the upper part. When a wiring is performed after the semiconductor layer of the layer 23 is so formed as not to form the layer 23 in the  upper part of a part of the layer 22, the conduction between the layers 22 and  23 can be securely performed without using a special technique such as a  through hole. When forming the layer 23, a method wherein a laser or electron  rays are irradiated resulting in the improvement of crystallinity of the semiconductor layer of the layer 23 with the crystal region of the aperture part on the layer 22 can be adopted.
