Patent JP-H04136688-A (JP)
Title: Heat pipe device
Inventor: HARADA TORU
IPC: F28D15/06
Filed: 1990-09-27
Abstract: PURPOSE:To control the transporting amount of heat of a heat pipe device by a method wherein a heater is controlled based on a detecting signal, outputted by a temperature detecting device detecting the temperature of a cooling area cooled by a heat pipe, to control the position in height whereat working fluid in the heat pipe is evaporated. CONSTITUTION:When a temperature detecting unit 7a detects that a temperature in a reserving chamber 16 has become lower than a set temperature, a detecting signal is transmitted to a control device 8 through a cable 10. The control device 8 sends the signal to an electric heating wire 6 to heat the electric heating unit 6a of the electric heating wire 6. Working fluid in the heat pipe 1 is condensed by being cooled in a fin unit 1b, then, flows down and is heated and evaporated by the electric heating unit 6a whereby heat transportation in the heat pipe 1 is effected. When a temperature in the reserving chamber 16 has become a value within an objective temperature range, the electric heating wire 6 becomes OFF condition and the heat pipe 1 returns to the inherent heat transporting cycle. By the repetition of this cycle, the heat pipe device 5 maintains the temperature in the reserving chamber 16 within the range of a set temperature. The position in height in the heat pipe 1, whereat the operating fouid is evaporated, can be regulated whereby the transporting amount of heat of the heat pipe device 5 can be controlled.

Title: Photoelectric isolation sensor
Inventor: HASHIGUCHI HIROSHI
IPC: G01V8/12
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To prevent an increase in an extinction rate by calculating the extinction rate on the basis of light reception quantity including limited offset data and a preliminarily set reference value. SOLUTION: A sensor reads cycle setting about a light emitting cycle preliminarily stored in an internal memory and waits until light emitting time. The sensor measures the offset data of a sample hold circuit 15 at the time when light is not emitted during this period. Next, the sensor transmits light emission control, i.e., a required synchronous pulse to a light emitting part side. Then, in a transmitting part side, a light emitting element emits the light, a light receiving element 12 receives the light, the light is inputted to a light receiving part control circuit 3, and an output (including the offset data) of the circuit 15 when the light is emitted.  Next, the measured offset data are compared with the upper limit value of the preliminarily set offset data, and when the offset data is equal to or more than the offset data upper limit value, a light receiving voltage is calculated by using a required expression. In the case of a monitoring mode, the extinction rate is calculated due to the expression such as extinction rate = (reference value -light receiving voltage)/reference value.

Title: Joining method of steel tube excellent in torsion fatigue strength
Inventor: KIMIYA YASUO
IPC: B23P11/02
Filed: 1993-10-18
Abstract: PURPOSE:To obtain fatigue life of several times and to improve fatigue strength by inserting a steel tube into the bracket hole having the inside diameter a little bit smaller than the outside diameter of the steel tube. CONSTITUTION:A steel tube 1 is forcedly inserted into a bracket hole 3 having the inside diameter max 0.6mm smaller than the outside diameter of steel tube, the tube end of the steel tube 1 is arc welded, forming a weld zone 6. In this way, the steel tube 1 is subjected to external pressure from a bracket 2, generating a compression stress advantageous to fatigue, further, because friction force is generated to absorb torsional torque, the stress due to torsion applied on the weld zone 6 is greatly reduced. Accordingly, all causes for lowering weld zone strength seen in a conventional method are eliminated. When an inside diameter of the bracket 2 is much smaller than the outside diameter of the steel tube 1, insertion of steel tube becomes difficult, also deforming steel tube, the difference is 0.6mm at most. By this method, the welding rod and welding condition become easy, reducing welding cost.
