IPC: F16N39/02
Filed: 1988-02-12
Abstract: PURPOSE:To prevent oil from being overheated by mounting a bypass circuit in addition to a cooler circuit and placing a change-over control valve which opens and closes according to the variation in temperature and pressure of oil at the separation point of the cooler circuit from the bypass circuit. CONSTITUTION:When oil is at the low temperature, a partition plate 22 inside a change-over control valve 16 is kept flexed toward an out port 25 and an inport 26 is kept open to a small chamber 21A. That is, a return piping 7A is communicated with a bypass piping 18 via each of a port 26, a small chamber 21A and an out port 24. As a result, oil is carried from the return piping 7A to the bypass pipe 18 via the control valve 16 without passing through a cooler 9, whereby preventing oil from being overcooled and the increase in pressure inside the return piping 7 associated with the increase in temperature of oil. When the temperature of oil get higher, the partition plate 22 inside the control valve 16 is flexed and deformed gradually toward the port 24 so that the return piping 7A will be communicated with the return piping 7B.

Title: Sound collection device for microphone and microphone with sound collection device
Inventor: SHIMIZU NAOKO
IPC: G10K11/28
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To allow a microphone pick up efficiently a sound even when its volume is small by providing a mount attached to/detached from the surrounding of a microphone head and a sound collection section surrounding around the microphone head at its mount to collect a sound entering the microphone head. SOLUTION: A mount section 2 attached to/detached from the surrounding of a microphone head 1 and a sound collection section 3 surrounding around the microphone head 1 at its mount to collect a sound are provided and the mount section 2 and the sound collection 3 are formed integrally. The sound section 3 is formed to be a cylinder longitudinally whose upper end is open so as to surround the head 1 and the mount section 2 is formed under the section 3. The sound is easily collected by adopting an outward spread shape for its upper opening 5 of the sound collection section 3, but since noise may be picked up when the opening is too wide, a proper width is selected. When the height of the sound collection display section 3 is too high, the sound collected by the sound collection section 3 is attenuated while being propagated in the sound collection section 3 and the sound volume reaching the head 1 is decreased, then the height of the sound collection section is selected properly and shaped to be resonated.

Title: Copying machine
Inventor: MISHIMA NOBUHIRO
IPC: G03G21/00
Filed: 1988-02-12
Abstract: PURPOSE:To easily identify that it is the display of a copying mode by lighting segment display elements respectively corresponding to a selected copying mode and a not-selected copying mode among the segment display elements forming a numeral value display part in different display forms. CONSTITUTION:As to LEDs of 101a, 101b and 101c corresponding to the color modes among the segments which displays the number of the head digit of the numeral value display part 101, the LED corresponding to the selected color mode is fully lighted and the LED corresponding to the not-selected color mode is half lighted. In other words, the display where full lighting and half lighting are mixed is performed when the color mode is displayed with the head digit of the numeral value display part 101. Thus, it becomes obvious that the head digit of the numeral value display part 101 does not display the numeral value but displays the color mode of a copied image.

Abstract: PURPOSE:To prevent getting out of a cell shape, generating an unstretched part, and stretch it equally, by cutting an unstretched block of a honeycomb shape material, inserting it between the belts, carrying it by snake motion between the belts, and after that, stretching it. CONSTITUTION:An unstretched block 7 of a honeycomb shape material is cut off, it is fed along the guide 14, and is inserted between the belts 11, 13. The unstretched block 7 which has been inserted between the belts 11, 13 is carried by means of friction force of the belt 11. In this case, since spring force is put to the tension roll in the direction shown by an arrow P, the unstretched block 7 is bent in the foil-laminated direction along a curvature of the roll, and is carried by snake motion. According to such a constitution, since each foil slips off each other, it is possible to get rid of entanglement between foils, which is caused by a cut burr on the cut surface.

Title: Optical card and its manufacture
Inventor: KANEHIRA ATSUSHI
IPC: G11B7/24012
Filed: 1988-02-15
Abstract: PURPOSE:To mass-produce a fine pattern with an excellent light-dark contrast by forming the light intercepting section of a recording layer by dyeing one surface of a base plate with a light-absorbing coloring matter. CONSTITUTION:The light intercepting section 14 of a recording layer 16 is formed by dyeing one surface of a protecting plate 11 with a light absorbing coloring matter. Recording and reading are performed by making laser light incident from the surface of the base plate 11 and, when the reading light reaches the light intercepting section 14 of the recording layer, the light is absorbed by the light intercepting section 14. Moreover, when the reading light is made incident to the light transmission section 15 of the recording layer, the light passes through the light transmission section 15 and reaches the rear surface of the optical recording layer 16 where the light is reflected. Furthermore, no special dyed layer is required because the protecting plate 11 can be dyed directly by a simple process. Accordingly, a fine pattern with an excellent light-dark contrast can be mass-produced.

Filed: 1989-02-14
Abstract: PURPOSE:To reduce the number pcs. of state supervisory information to be sent and to make supervision exact by expressing the state value of an N pcs. of continuous supervisory items in a slave station device side by the state value of 2N, sending the state value as the information of change point item in the monitor item, and decreasing the state supervisory information when a change point is continued. CONSTITUTION:A slave station device 2 defines the state of the N-number of the continuous supervisory items as the state value of 2N according to a transmission item, for which the supervisory item is determined in advance, and periodically sends only the change point item in the state value of the N-th item. A host station device 4 detects the change point item and the state value of 2N based on the state supervisory information from the slave station device 2 and the state supervisory information sent from the above mentioned slave station device 2. The states of the respective supervisory items are restored from the above mentioned change point item and the state value of 2N. For example, the slave station device 2 monitors every two continuous supervisory items and judges to which state those items are correspondent. Then, a state value P corresponding to a judged result is selected and sent. Accordingly, even when the transmission quantity of the state supervisory information is small,the supervision can exactly be executed.
