Title: Semiconductor layer
Inventor: GOTO CHIAKI
IPC: H01S5/00
Filed: 1986-02-12
Abstract: PURPOSE:To simplify the construction of a device, by constituting a beam radiation window with a grating lens. CONSTITUTION:A semiconductor layer chip 1 is arranged at the bottom of a cylindrical semiconductor laser case 10 whose inner part is air-tightly constituted. When travelling outwards from the case 10, a laser beam 2 radiated from the front end of the chip 1 passes through a circular radiation window 3 formed on the front surface. This radiation window 3 is constituted of a grating lens which acts as a convex lens, and arranged apart from the chip 1 by a distance equal to the focal length of the lens. Consequently, the laser beam 2 becomes a parallel beam 2' as a result of passing through the radiation window 3, and then radiated outwards. Thus it is unnecessary to install a special collimator lens outside the case, which simplifies the construction.

Abstract: PURPOSE: To remarkably improve work environment, by roughly removing casting sand from a cast product before its temperature drops and improving its cooling effect.  
     CONSTITUTION: A cast product at high temperature after unpacking its casting frame is fed onto a vibrating conveyer main body 2 by a conveyer 1 with casting sand as left attached and firstly the casting sand on its upper half part is removed at a position immediately below a shot blast 4.

Said cast product subjected to rough removal of the casting sand is fed to the subsequent processing step. The casting sand removed is dropped down together with shots onto a collecting plate 6, further dropped down onto the first separator 7 then the shot is separated from the casting sand, thus the casting sand is restricted to a rise of its temperature and cooled while passing through a conveyer 8 and the second separator 9.

Title: Cylindrical lithium battery
Inventor: OHIRA TSUKASA
IPC: H01M6/16
Filed: 1987-02-10
Abstract: PURPOSE:To retard the intergranular corrosion in a welding part and the stress corrosion caused by working strain and to increase high temperature storage performance by using a porous thin ferritic stainless steel plate which is previously heat-treated and containing a specified amount of each of Cr and Mo in a current collector. CONSTITUTION:A porous thin ferritic stainless steel plate which is previously heat-treated and containing 17.5-19.5 wt% Cr and 0.4-0.7 wt% Mo is used as a current collector of a sheet-like thin positive electrode. The porous thin stainless steel is heated in a vacuum or in an inactive gas atmosphere at 820-860 deg.C for heat treatment. Chromium forms the passive layer on the surface of the stainless steel to retain corrosion resistance, and molybdenum has about three times higher corrosion resistance than that of chromium and retards intergranular corrosion. By heat treatment, stress-strain caused by lath forming process is removed to retard stress corrosion. Thereby, the high temperature storage performance of a battery can be increased.

Title: Method for manufacturing sintered component
Inventor: TAKEMURA MASAO
IPC: F16C33/14
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To manufacture sintered components having a high quality under a low cost by a method wherein hydro-carbon oil is applied to any one of rust-proof liquid, sizing lubricant and cleaning liquid used in a manufacturing stage. SOLUTION: A cylindrical pressed powder member 10a is attained at a mold forming step 1 and a sintered body 10 is attained at a sintering step 2. The sintered body 10 is immersed into hydrocarbon oil acting as rust-proof liquid so as not to cause rust to be generated at the surface of the sintered body 10 at the rust-proof step 3. A sizing rod 13 is moved up and down within a hole 11 of the sintered body 10 at a sizing step 4 and then porous part or burrs at the inner circumferential surface 12 of the sintered body 10 are compressed again. The rust-proof liquid is utilized as sizing lubricant liquid. At a cleaning step 5, hydrocarbon oil which is the same as the rust-proof liquid is used as the cleaning liquid and then metallic chips generated an the porous portions of the sintered body 10 or generated during sizing operation are removed rather than removing the rust-proof liquid.  The sintered body 10 is heated at a drying step 6 so as to evaporate cleaning liquid. Since the hydrocarbon oil has a superior drying characteristic, it is completely evaporated and even if the oil is left as a completed product as it is, no cleaning liquid is left, so that a sintered component having a high quality can be attained.

Title: Tape recorder
Inventor: MACHIDA KEISUKE
IPC: G11B15/02
Filed: 1982-02-25
Abstract: PURPOSE:To obtain a tape recorder suitable for the reproduction of a cassette tape on which, for example, music for recorded orchestral accompaniment is  recorded lengthwise starting at a nonsignal part at the intermediate part of the  tape, by providing a means for inverting the running direction of the tape on  detecting a tape end and a means for stopping the run of the tape on detecting  the nonsignal component. CONSTITUTION:Once the accompaniment music for singing ends and a tape end comes, the transmissivity of light from a light emitting diode to a photodetecting element 39 varies and a tape end detecting circuit 40 supplies a tape-run inverting signal to a tape running direction controlling circuit 20; and driving circuits 22 and 26 invert the tape running direction from right to left with a temporary stop interposed. For example, when the tape is fed left at a high speed until the nonsignal part as the record starting point of music and both signals from magnetic heads are both ceased, a nonsignal part detecting circuit 38 detects a nonsignal state and supplies a tape run stopping signal to the tape running direction controlling circuit 20, thereby stopping the tape run.

Title: Internal combustion engine
Inventor: OKADA KOJIRO
IPC: F01N13/02
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To always accurately determine the deterioration of NOx catalyst regardless of the state of the NOx sensor. SOLUTION: The NOx concentration in the exhaust downstream of NOx catalyst 19, which occludes NOx in the exhaust in an excess oxygen atmosphere and discharges the occluded NOx in a decreased oxygen atmosphere, is detected by a NOx sensor 22. When the engine is operated in the decreased oxygen atmosphere where regenerative means is being executed or in the excessive oxygen atmosphere immediately after regenerative means has been executed, deterioration determination means determines the deterioration state value from the difference between two detected output values of the NOx sensor 22 taken at a predetermined time apart from each other. Then, deterioration of the NOx catalyst 19 is determined based on the difference between the deterioration state value and the deterioration determination value.  Further, deterioration of NOx catalyst 19 is determined by the relative detected values of the NOx sensor 22. Accordingly, deterioration of the NOx catalyst 19 is always accurately determined regardless of the state of the NOx sensor 22.
