Abstract: PURPOSE:To execute a processing at high speed and to improve the performance of the parallel computer by using only a supercube-like communication network which can execute a bidirectional notice, bringing data dispersed to each cell to an arithmetic operation extending all the cells and returning a result to all the cells. CONSTITUTION:When a processor is placed at each apex of a supercube and position information is expressed by a binary number, it is arranged so that the difference of positions between adjacent cells becomes '1'. In the first level of time, a bidirectional arithmetic operation is executed simultaneously to the X direction between the adjacent cells. Subsequently, in the second level of time, the arithmetic operation is executed simultaneously between cells in the Y direction, and in the third level of time, the arithmetic operation is executed simultaneously between cells in the Z direction. Next, the result of operation in the first level of time is calculated in the second level, and when its result is calculated simultaneously in the third level, the same value is stored in each cell. In such a manner, the processing is executed at high speed and the performance of the parallel computer is improved.

Abstract: PURPOSE:To make it possible to prevent the occurrence of burr when commutator pieces are machined and manufacture at a low cost, by forming a commutator by circumferentially installing a plurality of the segment commutator pieces made of a conductive metal through gaps in the outer circumference of a resin core material and providing chamfering parts in outer circumferential corners extending to these gaps. CONSTITUTION:Commutator pieces 42 are formed in a segment shape, for example, by pressing a copper plate and are circumferentially installed through gaps 43 in the outer circumference of a core material 41 made of a resin material. Terminal pieces 46 whose free ends are formed in a substantially U shape are integrally protruded in end parts of the commutator pieces 42. Chamfering parts 47 are installed in outer circumferential corners in the longitudinal direction of the commutator pieces 42.

Title: Variable capacity type turbine expander
Inventor: KATO TAKASHI
IPC: F01D9/00
Filed: 1990-11-21
Abstract: PURPOSE:To reduce the amount of leakage to the rear side of a second sidewall for reducing the load on a driver for capacity adjustment by a method wherein the inner circumferential part of the second sidewall is extended in the axial direction of a turbine impeller to form an L-shaped axial section, and an intermediate pressure chamber is formed between the second sidewall and an annular side plate. CONSTITUTION:P represents the pressure in an intermediate pressure chamber 9, P1 the pressure at the inlet of an entrance flow path 8, and P2 the pressure at the outlet. The pressure P varies depending upon the sizes of gaps at the inner and outer circumferences of a second sidewall 3 and a gap at the inner circumference of a slot 6, however, a relationship P1>P>P2 is established. As the second sidewall 3 having an L-shaped axial section is provided to form an intermediate pressure chamber 9, a thrust F= A(P1-P) is exerted on the second sidewall 3, where A is a sectional area perpendicular to the axial direction. By adequately adjusting the gaps, P=1/2(P1+P2) is established. The inner circumference of the second sidewall 3 serves as a weir, the differential pressure across the second sidewall 3 becomes small, resulting in an reduction of gas leakage amount to the rear side of the second sidewall 3.

Title: Method of exposing resist film
Inventor: TERADA TOMONORI
IPC: H01L21/30
Filed: 1989-12-08
Abstract: PURPOSE:To prevent a defective focal point caused by warping by setting a stage at the intermediate point between the nearest position and the fathest position from the light source for exposure, and thereafter exposing a resist film to specified light. CONSTITUTION:The measurements of the positions of a stage where the focal point in exposure is aligned are performed at a plurality of points. The stage is set at an intermediate point between the nearest position and the farthest position from a light source for exposure among the measured positions of the stage. Thereafter, a resist film is exposed to specified light. The exposed resist film is etched with developing liquid, and a mask having a specified pattern is obtained. That is, the setting of the stage at the intermediate position decreases the deviation from the focal point of the exposure with respect to the exposing surface of the resist film having warping. Thus, the exposure without defective focal point can be performed for the resist film on the surface of an element forming region having the warping in the exposure region.

Title: Disk cache control system
Inventor: SHIBATA NAOHIRO
IPC: G06F3/06
Filed: 1987-12-18
Abstract: PURPOSE:To perform a look-ahead transfer by a direct memory access (DMA) transfer by providing a dummy transfer mode in which a high-order controller does not transfer the data on an input/output bus to its host. CONSTITUTION:A part of the data of a disk device 3 is copied in a cache memory 9 and the data which do not exist in the memory 9 are read from the device 3 when a host makes read access. A dummy transfer mode in which a high-order controller 6 does not transfer the data on the input/output bus to its host is provided in addition to a mis-hit transfer mode. Therefore, a control section 5 actuates the controller 6 by setting a requested byte number (n) and an input/output controller 8 by setting a look-ahead byte number (alpha) in addition to the requested byte number (n) at the time of mis-hit. After the mis-hit transfer mode of the requested byte number (n) is completed, the dummy transfer mode of the look-ahead byte number (alpha) is executed and written in the memory 9. Therefore, when a mis-hit DMA transfer is made, a look-ahead DDMA transfer can be carried out easily and the hit rate can be improved.

Title: Symbol timing detection circuit for ofdm demodulator
Inventor: KIZAWA TAKESHI
IPC: H04L27/22
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a symbol timing detection circuit for an orthogonal frequency division multiplexing(OFDM) demodulator with which symbol timing is speedily detected while reducing the storage of signals at the symbol timing. SOLUTION: When there is a signal exceeding a threshold, that timing is stored as the symbol timing. Namely, that symbol timing is held just for a certain fixed term TD. When a signal having a peak higher than the held signal is inputted during the term TD, its position is newly stored as the symbol timing. When the symbol having the high peak is not inputted during the term TD, on the other hand, the held symbol timing is outputted as the symbol timing of a received OFDM signal. Next, after the symbol timing is sequentially detected, the window of high speed Fourier transformation (FFT) is shifted forward and the window is opened.

Any org. or inorg. base can be used for preparing the aq. alkali soln., but, sodium hydrogencarbonate and sodium hydroxide are pref., the former being esp. pref. It is still pref. if the extraction is conducted twice: first with an aq. soln. of sodium hydrogencarbonate and then with that of sodium hydroxide. The org. solvent is removed by distillation from the resultant org. solvent layer to obtain the modified Jinkoh oil. The addition of 10wt.% chromone compd.  e.g. 2-[2-(methoxyphenyl)ethyl]chromone} to the modified oil gives a product which emits fragrant smoke similar to Kyara oil.
