Title: Sunlight taking device
Inventor: YAMADA KAZUMI
IPC: F21S11/00
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To simplify the execution of work by comprising an outer frame mounted on an opening and an inner frame extended inside of the opening, and providing the inner frame with lighting prisms, a main body light distribution board, and an interior light distribution board. SOLUTION: Two lighting prisms 14, 15 are independently rotated corresponding to a position of the sun to take the sunlight in accordance with the movement of the sun. The taken sunlight is the approximately parallel light, and diffused by the main body light distribution board 16 and the interior light distribution board 17 to be distributed into a room. The total device including the interior light distribution board 17 can be mounted by mounting a body 5 on an opening 3 of an inclined roof 1, and mounting a daylighting device body 7 on the body 5, which simplifies the installation work. The interior light distribution board 17 is mounted on an inner frame 13, which dispenses with the mounting of the interior light distribution board 17 onto an interior side end of the body 5, and simplifies the work.

Title: Biological contact filtering method
Inventor: SATO SHIN
IPC: C02F3/06
Filed: 1989-10-05
Abstract: PURPOSE:To enhance the removal capacity of ammonia nitrogen in the treatment of raw water varied in load by passing raw water through a filter tower packed with a filter bed holding bacteria while alternately changing over the same to upward flow and downward flow at every 1-10 days. CONSTITUTION:Raw water is brought into contact with nitrifying bacteria held to a filter bed 2 while filtered by the filter bed 2 and ammonia nitrogen in raw water is oxidized to be removed. Raw water is passed through the filter bed 2 while alternately changed over to downward flow and upward flow at every 1-10 days. By alternately performing the downward flow passage and upward flow passage of water at this frequency, nitrifying bacteria oxidizing ammonia nitrogen can be allowed to live not only in the upper part of the filter bed 2 but also in the lower part thereof in much quantity and the quantity of nitrifying bacteria held by the whole of the filter bed becomes very much. By this method, the lowering of the removal capacity of ammonia nitrogen can be suppressed low with respect to load variation such that the concn. of ammonia nitrogen in raw water suddenly increased.

Title: Thin-film magnetic head
Inventor: YAMAMOTO KOTARO
IPC: G11B5/31
Filed: 1990-09-28
Abstract: PURPOSE:To decrease the under shoot quantity of recording and reproduced signals and to attain recording at a higher density by varying the length in the circumferential direction of at least one recording media of an upper pole and lower pole. CONSTITUTION:The lower pole 21 and the upper hole 22 are so formed that the respective pole lengths (P1, P2) thereof vary in the transverse direction of tracks. The sum of the HX distribution for the pole lengths in the respective pole length within the track width of the head, i.e. the integrated value in the transverse direction of the tracks of the HX distribution may, therefore, be simply necessitated to be considered for the reproduced waveforms over the entire part of the head at the pole lengths P1, P2 of the thin-film magnetic head. Since the peak values of the main signals exist in the same position, these values are added as they are. The positions where the under shoot arises vary with the pole lengths P1, P2, the peak waveforms of the under shoot quantity are broader than the peaks of the main signals. The under shoot quantity of the recording and reproduced signals are drastically decreased in this way and the magnetic recording at the higher recording density is possible.

Filed: 1991-10-07
Abstract: PURPOSE:To improve the operating margin against power supply voltage fluctuation and temperature fluctuation by preventing malfunction of a drive transistor(TR) driving an output TR against the voltage fluctuation and temperature fluctuation. CONSTITUTION:Since a constant voltage circuit 30 is provided to the output buffer, even when a power supply voltage VCC is decreased, a base-emitter voltage Vbe of a TR 31 is always kept constant.
