Title: Performance testing method for high temperature heat pipe
Inventor: HASEGAWA HITOSHI
IPC: F28D15/06
Filed: 1994-06-24
Abstract: PURPOSE:To calculate a heat transporting characteristic value of a heat pipe under a condition of an operating temperature range by a method wherein an evaporating part of a high temperature heat pipe is heated and held within an operating temperature range, a cooling pipe having a circular sectional area is wound around an outer circumference of a condensing part in a predetermined clearance and the cooling medium is flowed within the cooling pipe and cooled. CONSTITUTION:An evaporating part 12 arranged within a heating furnace 15 for a high temperature heat pipe 11 is heated, a flow rate adjusting valve 18 is opened and cooling water in a water storing tank 16 is flowed within a cooling pipe 14. Potassium contained in the working fluid is resolved within the heated evaporating part 12, further heated and evaporated. Then, the working fluid moves within the heat pipe 11 toward the condensing part 13, is contacted with an inner circumferential surface of the condensing part 13 cooled and kept at a low temperature with cooling water flowing within the cooling pipe 14 and then condensed. The cooling water absorbing heat becomes hot discharged water and then the water is recovered in a hot discharged water tank 17. Accordingly, it is possible to calculate a heat transporting amount of the high temperature heat pipe 11 in reference to an amount of and a temperature of the hot discharged water.

Title: Mold for resin molding of semiconductor element
Inventor: HAYAMA TADAO
IPC: B29C45/27
Filed: 1988-07-04
Abstract: PURPOSE:To make a resin flow into cavities easily and prevent a sealing resin from producing voids by making each cross section area of runners connecting to a pot part smaller gradually as its area approaches to a pointed end and installing resin-accumulation parts at the pot part side of the cavities. CONSTITUTION:A part of each runner 2 approaching to the pot part 1 is thicker and such a part becomes thinner gradually as its part moves away from the pot part. Resin-accumulation parts 6 are installed at each cavity within a range 1-5 which is calculated from its runner' utmost end out of mold cavities 4 connecting to each runner through gates 3. Since each runner tapers down to each point, a sealing resin is difficult to reach the pointed end and then, the sealing resin supplied newly from the pot part flows in from the cavity which is in the vicinity of the pot part 1 one after another; besides, the resin is accumulated even in the resin-accumulation parts 6 which connect to each runner 2 through the wide gates. This approach prevents the sealing resin from producing voids.

Title: Integrated circuit
Inventor: KUBINEC JAMES J
IPC: H04B3/54
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To reduce the number of pins by connecting a second filter to a chip function element to constitute a transceiver, exchanging bit data from a power source line to obtain serializing/non-serializing configuration and transferring a signal between chips. SOLUTION: A chip function element 208 of an IC 200 transfers parallel bit data to a transceiver 206 and serializes plural kinds of bit data into a serial data stream. The transceiver 206 outputs it at a high speed, permits it to be a high frequency component with a high-pass filter 204 and transmits it to IC 210 with a power source line Vcc. The high frequency component of the power source line Vcc is extracted by the high-pass filter 214 of IC 210, transmitted to the transceiver 216 to be non-serialized and returned to parallel bit data at the time of transmission. In this way, a serial link is constituted between ICs 200 and 210 with the power source line Vcc. Then, parallel data exchange which is executed conventionally by the plural pins is serially executed through the power source pins and becomes replaceable for a single power source pin.

Title: Internal flaw detecting method for structure
Inventor: YAMAZAKI KENICHIRO
IPC: G01N25/72
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To visualize a filler changing condition as a thermal image so as to detect a insufficiently filled position or the like by measuring radiation energy on a structure surface due to heat generated when the filler charged inside the structure is hardened. SOLUTION: In maintenance work for charging a filler such as resin or mortar group filler into a lift part in a tile or mortar, for example, an internal defect due to insufficient filling is detected by means of an infrared radio meter. The infrared radiation thermometer is arranged so that a structure surface including an objective part to be repaired can be photographed, and then, a thermal image is recording in a floppy disc, for example, in every predetermined time continuously after the filler is charged. According to analysis of the best thermal image among the recorded ones, it can be determined whether the filler is completely charged to a clearance to be repaired or not, and a defective repair position can be identified. In reinforcement of a steel plate, a similar method can be applied to a process for charging a filler between a frame and a steel plate.

Title: Reflecting-type optical encoder plate
Inventor: UENO ICHIRO
IPC: G01D5/30
Filed: 1988-07-05
Abstract: PURPOSE:To design an optical system with larger degree of freedom and to prevent the change of an output resulting from the surface vibration by forming an encoder plate to have such a cross section in a moving direction that the depth from the plate surface to a wall surface of a pit is continuously changed. CONSTITUTION:A cross section of a rotary encoder disk plate 1 having a pit 3 in a circumferential direction thereof is an isosceles triangle having a plate surface as the base. The depth of the vertex is 3/8lambda, lambda being the wavelength of laser beams. The width is set to be 0.4w-w, e.g., 0.7w wherein (w) represents the diameter of a light spot 6. And the length is elongated. The width of a land portion 4 between pits 3 is set not smaller than the diameter (w), for example, equal to (w). Thus, the relation between the strength of reflecting light and the width of pits 3 when the center of the spot 6 falls on the center of the pit 3 becomes as indicated in Fig. (a). The strength of reflecting light is about 10% when the width of the pit 3 is 0.4-1 times (w), whereby the optical system of the device can be designed with larger degree of freedom. Moreover, even when the diameter (w) of the spot 6 and the reflecting light strength are changed because of the surface vibration when the disk plate 1 is mounted to an input shaft 7 with poor accuracy, an output change is less observed as long as the surface vibration is within a range.

Title: Continuously variable transmission
Inventor: KITAMURA MASAAKI
IPC: F16H15/16
Filed: 1990-06-26
Abstract: PURPOSE:To automatically change speed steplessly without high-priced parts and electrical control by displacing a speed change ring in its axial direction using a cam having an inclined face at the end surface and a spring for displacing the cam according to the load of an output shaft. CONSTITUTION:During no-load of an output shaft 26, a bearing 40 is forced to press an inclined face 4a by a spring 45 to clamp a portion of a cam 39, which has the minimum axial thickness, to support the cam. In such a condition, the output shaft 26 can be rotated at high speed by suitably setting the positional relationship of a speed change ring 38 to a cone 32. When load is applied to the output shaft 26, the rotating force produced by the load is transmitted from the cone 32 to the speed change ring 38 to produce the rotating force in the cam 39. The rotating force is equal to the load torque in magnitude and opposite in direction. Whereupon, an inclined face 49 of the cam 39 displaces the bearing 40 against the spring 45, so that the cam 39 is rotated and displaced in the axial direction. Thus, the contacting position between the speed change ring 38 and the cone 32 is changed to attain a suitable speed change ratio.
