Title: Scroll compressor
Inventor: NAGATOMO SHIGEMI
IPC: F04C18/02
Filed: 1982-03-31
Abstract: PURPOSE:To raise the compression ratio and the efficiency of a scroll compressor and to reduce the size of the same, by making the shape of the top end portion of a fixed spiral vane located near the center of the scroll and that of a movable spiral vane different from each other such that the volume of a compression space is decreased continuously. CONSTITUTION:Top end portions 21a, 22a of a fixed spiral vane 21 and a movable spiral vane 22 are shaped such that they are held in contact with each other at two points from the time before the final compression position of the scroll to the time when the scroll comes to the final compression position and the volume of a compression space P formed between the two vanes 21 and 22 is decreased continuously, as shown in the drawing. With such an arrangement, the volume of the compression space P at the final compression position where compression is terminated is made sufficiently small, so that most of the compression gas is discharge to the outside. Therefore, it is enabled to increase the compression ratio without increasing the number of turns of the vanes and the size of the entire structure. Further, since high-pressure gas is not leaked from the compression space P into a succeeding space, the efficiency of the compressor can be raised.

Title: Detection for incoming direction of wave
Inventor: TAKENAGA KAZUO
IPC: G01C13/00
Filed: 1985-03-18
Abstract: PURPOSE:To enable highly accurate detection of the incoming direction of waves even with a low cast and simple stable platform, by adding an acceleration sensor to a horizontal-way acceleration sensor vertical thereto to determine mutual correlation between outputs thereof. CONSTITUTION:Horizontal (X and Y axes)-way and vertical (Z axis)-way acceleration sensor are mounted perpendicular to each other on a stable platform provided in a float to detect the vectors of acceleration generated based on waves different in the wavelength reaching the float from various directions. Mutual correlations of X-axis and Y-axis detection outputs to the Z-axis detection output of incoming waves are calculated separately as cross spectrum for each wavelength of the waves to compute the arc tangent of the ratio between imagenary parts (guadrature spectrum) of both the cross spectrums. Thus, incoming directions of waves varied in the wavelength with respect to the X axis or Y axis are detected separately.

Title: Semiconductor signal line replacing circuit
Inventor: GOTO HIROSHI
IPC: H03K17/00
Filed: 1986-03-12
Abstract: PURPOSE:To replace signal lines by crossing the 1st and 2nd plural signal lines and arranging a semiconductor element having the gate of the equi-potential with the floating gate of a variable PROM to all cross points thereby allowing each variable PROM to select ON/OFF memories. CONSTITUTION:Semiconductor elements Tr1-Tr9 are inserted respectively to the cross points of respective signal lines in a replacing circuit replacing the 1st signal lines A-C into the 2nd signal lines (a)-(c) and floating gates EEPROMP1-P9 are connected respectively to gates of the semiconductor elements. When a positive charge is stored in the floating gate FG of the EEPROM P, the gate acts like an ON memory and when a negative charge is stored therein, the gate acts like an OFF memory. Since the floating gate FG is of equi-potential with the gate G of the semiconductor element Tr, when the connected EEPROM acts like the ON memory, the semiconductor element is conductive, and at the time of acting like the OFF memory, the element is nonconductive. That is, the constitution change of the signal line replacing circuit is much facilitated by rewriting the EEPROM memory.
