Title: Radio wave anechoic room
Inventor: ISHINO TAKESHI
IPC: H05K9/00
Filed: 1989-06-22
Abstract: PURPOSE:To improve absorbing characteristic for low frequency band without reducing high permittivity by so coupling mechanically processed sides of a tile to the mechanically processed sides of adjacent tiles that the tiles are magnetically coupled in a direction of magnetic fluxes of a ceiling and sidewalls. CONSTITUTION:Ferrite tiles have two sets of parallel sides in a square shape. The parallel sides 20a, 20b of one set are precisely machined in parallel, and those of the other set are not necessarily machined. The ferrite tiles are so adhered to a ceiling 12 and wall faces 14, 16 that the precise parallel sides of the tiles are disposed adjacent to each other. Accordingly, the tiles are adhered substantially without gap in a direction N in which a sample and a reception antenna are disposed to obtain a large permittivity in the direction N. Small gaps exist between the tiles in a direction M perpendicular to the direction N, the permittivity in the direction M is small, but it does not affect the influence of absorbing characteristic of a radio wave unechoic room. Thus, even if all the sides of the tiles are not machined, the unechoic room having excellent low frequency radio wave absorbing characteristic is obtained by the tiles having effectively high permittivity.

Title: Cache memory control system
Inventor: YAMAMOTO AKIO
IPC: G06F12/08
Filed: 1987-06-26
Abstract: PURPOSE:To improve the availability of a buffer storage device by giving the using right to a request for a cache directory part and processing simultaneously plural requests in case an access request is received from another requester while a certain request is processed. CONSTITUTION:The requests of the input/output processors IP0 and IP1 serving as requesters are processed in parallel with each other. As a result, the request of the IP0 is held by registers 34 and 35 with the request of the IP1 held by registers 36 and 37 respectively in terms of the access address of a cache storage part WS8. Thus both requests are processed simultaneously via the WS control in case the access banks of WS8 of both requests are different from each other. When both requests give accesses to the same bank, the priority is secured by the WS bank control. If the normal request processing like the request of the IP1 has a cache mistake during the parallel operations, a line is transferred from a main storage device after the same line request is processed.

Title: Non-sintered type cadmium anode for alkaline storage battery
Inventor: TAKEMURA MASAKAZU
IPC: H01M4/24
Filed: 1986-07-07
Abstract: PURPOSE:To obtain a cadmium anode that permits a high rate of usage by adding a specified amount of indium or indium compound to a cadmium anode, thereby improving the capacity of the anode. CONSTITUTION:The anode is composed of cadmium hydroxide as the main active material, and cadmium metal, indium or indium compound as auxiliary materials for charging. The amount of indium or indium compound added is 0.01 - 5.00wt% calculated in terms of indium in relation to the active cadmium. If the cadmium anode containing indium or indium compound is charged and discharged in alkaline electrolytic solution, therefore indium atoms are substituted in cadmium metal crystals. This causes lattice defects, making the crystals unstable. The electrochemical reaction is thereby enhanced, producing cadmium metal with a high rate of usage and increasing the rate of usage of the electrode itself.
