Title: Stacked heat exchanger
Inventor: ICHIYANAGI SHIGEJI
IPC: F28F3/08
Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To dispense with a usual process of fitting inlet and outlet pipes, to lessen the number of components, to cut down the number of machining processes, to reduce the cost of manufacture, also to make a cooling case compact and, besides, to ensure an effective core area sufficiently, by providing a fluid introducing passage and a fluid discharge passage integrally in an end plate part, in regard to a double tank stacked heat exchanger.

Title: Slow reproducing device
Inventor: SHIMURA FUJIO
IPC: G11B15/467
Filed: 1996-08-16
Abstract: PROBLEM TO BE SOLVED: To enable good reproduction even in any slow reproduction by executing a linear feeding when the slow reproduction is executed at a speed above a prescribed multiple speed with respect to the tape traveling speed at the time of recording and an intermittent feeding when executing at lower speed. SOLUTION: In the case when the slow reproduction at a relatively slow speed up to, for example, 1/4 multiple speed of good data reproduction efficiency is executed, the slow reproduction is executed by a linear feeding at the tape traveling speed up to this 1/4 multiple speed. On the other hand, when the slow reproduction of a relatively low speed (for instance 1/10 multiple speed) is executed, the magnetic tape is made to travel only for the 4-frame time at the 1/4 multiple speed, thereby a JOG processing circuit 5 write the entire data for one frame in a frame memory 7 so that the data reading out of this frame may be started after the 4-frame time. The slow reproduction is executed by the intermittent feeding to alternately execute the control of traveling and stopping to stop the magnetic tape for the remaining 6-frame time necessary for embodying the 1/10 multiple speed.

Title: Solid-state laser
Inventor: YAGI SHIGENORI
IPC: H01S3/0941
Filed: 1988-08-31
Abstract: PURPOSE:To enable a laser medium to efficiently absorb LD light rays so as to improve an oscillation energy efficiency by a method wherein an optical guide, which enables the light rays of a semiconductor laser to be obliquely incident on the laser medium, is provided. CONSTITUTION:An exciting light ray 12 for an LD1 is made to be obliquely incident on a laser medium 2. In result, the optical path inside the laser medium 2 becomes long, so that the light rays 12 are effectively absorbed in the laser medium. Furthermore, a part of the exciting light rays 12 reflected by the surface of the laser medium 2 is reflected again by a reflecting surface 71 of an optical guide 7 to make its traveling direction changed and made to be incident on the laser medium 2 again. As mentioned above, the exciting light rays 12 are almost absorbed in the laser medium 2 while they are reflected two or more times in a triangular space constituted with the surface of the laser medium and the reflecting surface 71. Therefore, the LD light ray has a little variation in wavelength and also in an absorbing coefficient, but the laser medium can be effectively excited. The heat generated in the laser medium is transmitted to a cooler 8 through a thin filler 61 and a holder 6 and finally radiated outside from a heat radiating fin 81.
