Title: Loop transmission system
Inventor: WATANABE AKIRA
IPC: H04L12/433
Filed: 1978-07-11
Abstract: PURPOSE:To know the possiblity for transmission immediately by providing the answer queuing period for the reception station to the transmission station after end of the transmission, and thus to reduce greatly the load of the software for the computer. CONSTITUTION:A circular connection is given via transmission line 1 to Su (station unit) A, B, C and D to which computers C-A, C-B, C-C and C-D are connected respectively. And for example, in case SuA detects special pattern GA to acquire the transmission right and thus discontinues the repeating action to send transmission date 21 given from computer C-A to SuC, SuC draws the transmission data into the self-station in the course of repeating of the data. And the repeated data is thrown away at SuA. Then SuA transmits the flag pattern continuously even after end of the transmission to wait for the answer of SuC. On the other hand, SuC discontinues the repeating action after end of the reception and performs the repeating action again after formation and transmission of the answer information. And SuA transmits the answer information to the local computer C-A and transmits GA to give the transmission right to other station units and then to be reset to the repeating action. As a result, computer C-A can proceed immediately to the next action.

Title: Breath current sensor
Inventor: BABA HIROYUKI
IPC: G10L15/28
Filed: 1988-04-06
Abstract: PURPOSE:To reduce the cost and to improve the detection precision by providing a front air chamber in the front of a microphone and arranging plural sound holes connected to this chamber in a curved front plate. CONSTITUTION:A front air chamber 3b is provided in the front of a microphone 4, and plural sound holes 4a connected to this chamber 3b are arranged in a curved front plate 3a. Since the breath current reaches the microphone 4 from any sound hole 4a through the front air chamber 3b, plural sound holes 4a have the same function as plural microphones through the front air chamber 3b. Consequently, only one detecting microphone 4 is required, and an unnecessary band is easily eliminated because the front air chamber 3b and sound holes 4a constitute an acoustic high-cut filter. Thus, the constitution is simplified and the cost is reduced, and detection is surely performed.

Title: Encoder and optical device
Inventor: YAMAUCHI HARUHIKO
IPC: G01D5/30
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To improve resolution and to prevent deterioration of an S/N ratio by obtaining an encode having an optical pulse plate and an optical device adequately using the encoder. SOLUTION: A light beam from a light source 1a passes through a polarization beam splitter 2 and a 1/4 wavelength plate 3 to become a circular polarization and to illuminate a circumference of an optical axis A on a pulse plate 4. A reflection light reflected by a refection section 4a of the pulse plate 4 passes through the 1/4 wavelength plate 3 to become an S polarization and to be totally reflected by the polarization beam splitter 2 and it is imaged on the pulse plate 4 as an inverted image by virtue of a lens 5 and a mirror 6. When the image portion is a non-reflection section, it is detected that the portion is a dark one by a light receiving section 1b. Conversely, when it is imaged on the refection section 4a, it is reflected thereby to become the circular polarization passing through the 1/4 wavelength plate 3 to become a P polarization.  It totally passes through the polarization beam splitter 2 and is detected by the light receiving section 1b as a bright condition to be converted to an electric signal.

Since the contact of the relay 90 is opened resultantly, current supply to an electromagnetic clutch 5 is interrupted and operation of the compressor 25 is stopped. Thus, since current supply to the electromagnetic clutch 5 can be interrupted in a reliable manner when the compressor 25 is locked, it is enabled to protect the bearings for the clutch 5 and to prevent damage of the belt.
