Title: Blank for tool die and its production
Inventor: PERU BIRUGUREN
IPC: B22F7/08
Filed: 1985-06-18
Abstract: The invention relates to a blank for a tool die, made of compound steel with a core of high speed steel and a surrounding ring of a different steel, said ring bringing about a prestress in the core. According to the invention, the prestress is due to the fact that the core consists of a high speed steel powder which has been compacted to full density, that the ring consists of a steel alloy, the residual austenite transformation to martensite and consequent volume increase of which is zero or considerably less than the residual austenite transformation to martensite of the high speed steel after the same heat treatment, and that the blank has been hardened and annealed to create in the core a compression stress as a result of the obstruction by the surrounding ring of the volume increase of the core.The invention relates also to a method for manufacturing such blanks. A high speed steel powder is filled into a thick-walled pipe, said pipe consisting of a steel different from high speed steel. The pipe is closed and subjected to hot isostatic compaction causing the high speed steel powder to become compacted to full density, forming a compact core in the pipe, so that a compound material is obtained. The pipe is cut into several discs or pieces of suitable lengths. The material is hardened and annealed, the high speed steel core during heat treatment undergoing a greater residual austenite transformation into martensite than the surrounding ring, a compression stress thus being created in the core.

Abstract: PURPOSE:To easily measure a position and speed of a traveling body, by a device wherein a light is irradiated from the traveling body onto projectins formed on a route with a given interval therebetween and a change in irradiated positions is taken out as an electric signal and then subjected to proper calculations. CONSTITUTION:A light from a light source mounted on a traveling body is irradiated onto porjections formed on a route with a given interval therebetween, and a change in irradiated positions is detected by a photosensor mounted on the traveling body. Thus, detected signals are processed to measure a position and speed of the travling body. On this occasion, it is not required to provide a special equipment such as a reflecting plate. For example, a light from a light source 1 mounted on a travling body 9 is irradiated onto projections 8 with a given interval therebetween and the reflected light is detected by a photosensor 2. By so doing, signal output from the photosensor 2 is varied depending on ruggedness of the projections 8. Thus, a position and speed of the travling body 9 can be obtained through signal processing using a position/voltage converter 3 and a comparator 4 and through computing operation using calculators 6, 7.

CONSTITUTION:A power source is thrown to operate a compressor 1 to a rise-up routine. A three-way valve 7 is opened to the side of a first cooler 4 to measure the temperature At of a freezing chamber A and the compressor 1 is operated continuously until the temperature At becomes lower than a set value. Subsequently, the temperature Bt of a low temperature freezing chamber B is measured after opening the three-way valve 7 to the side of a second cooler 6 and the compressor 1 is operated continuously until the temperature Bt becomes lower than a set value. The ordinary freezing chamber A and the low-temperature freezing chamber B are cooled sequentially and alternately by switching the three-way valve 7 alternately until the temperature At and the temperature Bt arrive at the set values. When the temperature At and the temperature Bt become lower than the set values, the compressor 1 is stopped and the operation of a refrigerator enters into a ordinary routine. In the rise-up routine, the value of the temperature reduction, which becomes a reference upon switching the three- way valve 7, may be set at a proper value. Further, difference temperature reductions may be selected for the ordinary freezing chamber A and the low-temperature freezing chamber B.

Title: Continuously variable transmission control device
Inventor: MURAKAWA RYUJI
IPC: F16H9/00
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To reduce shift shock in a gear change range converting time, as well as to secure the forward running even though a passage converting means for forward running is made impossible to convert when a forward running range is selected. SOLUTION: A changeover valve 220 converts an oil passage connected to an advance clutch 27, while a change-over valve 230 converts an oil passage connected to the rearward running brake 28. The oil passages of the change-over valves 220 and 230 are converted by a control pressure applied from a solenoid valve 210. The change-over valve 220 has a normal oil passage 221, and a throttle oil passage 222 with the oil passage area smaller than that of the normal oil passage 221. When a D range is selected from an N or P range by a shift lever 260, the throttle oil passage 222 of the change-over valve 220 is selected, so as to raise the hydraulic pressure applied to the advance clutch 27 slowly. Consequently, the shift shock is reduced. And since an operation oil can be fed to the advance clutch 27, even though either oil passage of the changover valve 220 is selected in the D range, the forward running in the D range can be secured.
