Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To provide an optical controller capable of controlling the transmitted quantity of light with simple structure by small power consumption without reducing an opening ratio being the occupied ratio of an opening to an entire picture display surface. SOLUTION: An opaque movable shutter 11 formed of shape memory alloy which is energized to generate heat is supported to be rocked by a hinge part 12 electrically connected to an upper electrode 2 existing at a part other than the position of a cavity part 13, and a power source impresses charge on a lower electrode 21 provided at the bottom part of an insulating substrate 1 and the upper electrode 2 existing above the electrode 21. Then, the shutter 11 opens the cavity part 13 by the electrostatic force of the charge impressed by the power source, and stops by coming in contact with a projection part 24. Thereafter, in the case of closing the cavity part 13, the shutter 11 is energized to be heated so as to restore its form, and closes the opening.

Abstract: PURPOSE:To decide surely input disconnection by applying the result of compari son between a reception equalization output signal and a threshold value and a clock having an intermediate phase of an identifying point of the reception equalization signal to an FF and allowing a calculation discriminating circuit to count an output of the FF. CONSTITUTION:The reception signal is subject to amplification 1, equalization 2 and fed to an identification circuit 3, a clock regenerating circuit CLK4 and a comparator circuit 5. The CLK4 generates a clock signal CK selecting a timing identified by the identification circuit 3, generates a clock ck having a phase different from that of the signal CK by 180 deg., and the clock ck is fed to a clock terminal C of the FF6. The comparator circuit 6 uses transistors (TRs)Q1, Q2 to compare the threshold value Vcc.R6/(R6+R7) and the input signal, and when the input signal is larger than the threshold value, logical H is outputted and fed to a data terminal D of the FF6. The output of the FF6 is fed to a count decision circuit 7, and when the count within a prescribed time exceeds a prescribed value, an alarm is outputted (8). Thus, the input disconnection is detected accurately.

Also, a comparison circuit 30 compares the detected signals from the sensors 18, 20 with the set value and converts the detected signals into the percentage of the set value. And these data are sent to an alarm circuit 34, which, in turn, generates alarms in plural number of stages for each maintenance-requiring part. These alarms, together with the display time of an integrated time indicator 38, preset reference time, and percentage, are displayed with top priority on a display unit 36. Thereby, accurate maintenance can be performed before the whole system becomes inoperative.

Title: 2-cylinder rotary compressor
Inventor: NAGAGAWA MAMORU
IPC: F04C29/12
Filed: 1988-09-09
Abstract: PURPOSE:To provide an excellent 2-cylinder rotary compressor which reduces an influence exercised directly on the one connection spot by a connection work at the other connection spot and prevents leak of fluid to be compressed by a method wherein a connection spot between the one connection pipe on the closed container side and the one piping on the accumulator side and a connection spot between the other connection pipe and the other piping are positioned at different distances from the wall surface of a closed container, and the two spots are separated away from each other with a distance therebetween. CONSTITUTION:The lengths of connection pipes 9a and 9b installed on the closed container 1 side are differed from each other, and lengths d1 and d2 of joint spots between the connection pipes and their respective pipings 8a and 8b from the wall surface of the closed container 1 are different from each other. A connection spot between the other connection pipe and the piping is prevented from oxidization due to the flame of a burner used during joining of the one connection pipe, and during joining of the other after joining of the one, the connection spot of the pipe, joining of which is completed, is prevented from heating by the burner flame, and working efficiency can be improved. This constitution prevents the occurrence of poor joining between the connection pipe and the piping and prevents leak of fluid to be compressed.

Title: Cutting tool made of high abrasion-resistant titanium carbide-nitride radical cermet
Inventor: KOTANI JIRO
IPC: B23B27/14
Filed: 1988-09-09
Abstract: PURPOSE:To obtain the abrasion resistance of the cutting tool in the title by forming, on the surface of the tool, the surface hard layer of 1 to 10mum in average layer thickness, which is composed of a hard phase of a single-phase structure and a combination phase. CONSTITUTION:When a cutting tool made of TiCN radical cermet is sintered, a temperature rising process from a room temperature to a predetermined temperature in the range from a denitrification starting temperature to a liquid phase appearing temperature is made to be a denitrification atmosphere such as a vacuum or a decarburization atmosphere in which CO2 gas is contained. And the rest of the process is made to be a nitrogen atmosphere. Then the surface layer of 1 to 10mum in average layer thickness is formed on the surface area of TiCN radical cermet after sintering, which is composed of the hard layer of a single-phase structure and a combination phase. This surface layer becomes considerably hard rather than the inside area of the cermet which is superior in tenacity and composed of a hard phase with a double- phase structure or the mixed organization of the double-phase structure with the single-phase structure, and a combination phase. Then when this surface layer is adopted in a tool for high-speed cutting or high-feed cutting, good cutting performance is available for a long term.

Title: Electric field strength information sending system for cordless telephone system
Inventor: FUKUSHIMA JUNICHI
IPC: H04W40/12
Filed: 1994-09-21
Abstract: PURPOSE: To set the radio speech path in the best condition out of plural available radio speech paths at the time of setting a radio speech path in the cordless communication system. CONSTITUTION: The radio wave having a limit field strength for speech is applied from a reference radio wave generator 5 to antennas 105 and 205, and outputs of radio transmission/reception parts 103 and 203 at this time are preserved as discrimination reference values in non-volatile memories 104 and 204. When a radio speech path is set, difference values between outputs of radio transmission/reception parts 103 and 203 for the received radio wave and stored discrimination reference values are used as reception field strength information for radio speech path selection.  Since difference values between reception field strength data and discrimination reference values are used as reception field strength information, influences of variances in input/output characteristics of radio transmission/reception parts included in two values are cancelled by each other to show the accurate degree of margin of the field strength; and thereby, the optimum radio speech path is selected and set.
