Title: Optical scanner device
Inventor: KOMURA TSUKASA
IPC: G06K7/10
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To make the scanning angle of an optical scanner device, which makes an optical scan by turning a reflecting mirror in the one-dimentional direction, without increasing the size of the device. SOLUTION: On both sides of a mirror part 33 where the reflecting mirror is formed, spring parts 35 and 37 are formed directly and formed into a rectangular wave shape, and piezoelectric elements are adhered to mount parts 47 and 46 connecting the spring part 35 and an external frame 31 to form a piezoelectric unimorph for driving, thereby constituting an optical deflecting element for optical scanning. Consequently, the reflecting mirror and a coil for vibration generation need not be supported by the spring parts 35 and 37 unlike a conventional device, and the spring parts 35 and 37 can be made small. Further, since the spring parts 35 and 37 are formed into a rectangular-wave shape, the spring parts 35 and 37 can be shortened in overall length while their substantial lengths are maintained.  Therefore, while the scanning angle is secured, the deflecting element, and then the optical scanner device, can be made small-sized.

Title: Power failure detection system
Inventor: YAEJIMA MAMORU
IPC: H02H3/24
Filed: 1986-10-27
Abstract: PURPOSE:To put a computer in normal operation even in case of a longer instantaneous interruption of a commercial AC power source when the constitution of the computer is small by detecting the output voltage level of a batch rectifying circuit part by using a comparator and sending out a power failure detection signal. CONSTITUTION:When the commercial AC power source is disconnected to lower the output of the batch rectification part and the voltage at the variable reed A of a variable resistor 14 drops below a division voltage generated by resistances 20 and 21, the output of the comparator 22 falls almost to 0V, a transistor 23 turns off, and the photodiode of a photocoupler 24 turns off, thereby sending out the power failure detection signal. If the load of a voltage converting circuit varies owing to the alternation of the constitution such as an increase or decrease in the memory capacity of the computer and an increase or decrease in the number of channels, the time when the output voltage of the batch rectification part drops at the time of a break of the AC commercial power source varies, so the time for sending out the power failure detection signal also varies at the same time. Therefore, when the computer mechanism is made small, the computer can be put in normal operation even in case of a longer instantaneous break of the commercial AC power source.

Title: Cooling and heating apparatus
Inventor: KURACHI MASAO
IPC: F25B13/00
Filed: 1988-10-11
Abstract: PURPOSE:To sufficiently exhibit the ability of a first auxiliary heat exchanger while preventing a refrigerant liquid from flowing backward into a compressor, and to make a supercooling degree larger to enhance the ability of a heat source side refrigerant cycle by providing a third auxiliary heat exchanger in the heat source side refrigerant cycle and by exchanging heat between the outlet side refrigerant of a heat source side heat exchanger and the outlet side refrigerant of the first auxiliary heat exchanger during a cooling operation. CONSTITUTION:A third auxiliary heat exchanger 13 carries out heat-exchanging between the outlet side refrigerant of a heat source side heat exchanger 3 and the outlet side refrigerant to a first auxiliary heat exchanger 8 and is arranged so as to be actuated by means of a solenoid valve 14 in a cooling operation. The solenoid valve 14 is opened during the cooling operation, and the outlet side refrigerant of the heat source side heat exchanger 3 and the outlet side refrigerant of the first auxiliary heat exchanger 8 exchange heat with each other in the third auxiliary heat exchanger 13. Accordingly, even if the outlet side refrigerant of the first auxiliary heat exchanger is brought into a two-phase state by making the opening degree of a cooling decompressor larger in order to permit the first auxiliary heat exchanger to sufficiently exhibit its ability, the refrigerant liquid is prevented from flowing backward into a compressor and the supercooling degree can be made larger. Therefore, the ability of a heat source side refrigerant cycle can be enhanced.

Title: Snowfall sensor
Inventor: MORIOKA HIROSHI
IPC: G01W1/14
Filed: 1988-10-11
Abstract: PURPOSE:To securely detect and indicate the beginning of a snowfall by combining an electrode plate, a temperature detector which detects the temperature of snow, and a detecting circuit which detects electrodes being bridged through a drop of water on an insulating substrate. CONSTITUTION:The electrode plate 11 is installed outdoors with its electrode surface 11b up. When it snows, snow S is accumulated in a snow receiver 13a, so its temperature is detected by temperature detector 13. Further, the sow S melts in a short time and resulting drops W of water drip on the electrode plate 11 on the electrode plate 11 to bridge the gap (d) between electrodes 11b1 and 11b1 through the drops W of water. At this time, the electric insulation resistance value between the electrodes 11b1 and 11b1 decreases greatly, so the detecting circuit 12 detects that and sends out an output signal S when the temperature detected by the temperature detector 13 is <=0 deg.C. The detecting circuit 12 judges that the drops W of water are due to not snow, but rain and does not send the output signal S when the detected temperature of the temperature detector 13 is >0 deg.C.

Title: Scroll fluid machinery
Inventor: ISHIHARA NOBUAKI
IPC: F01C19/08
Filed: 1993-10-13
Abstract: PURPOSE:To reduce sliding loss due to pressing force of a chip seal of a scroll fluid machine and improve its sealability at the same time. CONSTITUTION:In a scroll fluid machine such as a scroll compressor, an elastic body 18 and a chip seal 19 which may be integrated with each other are fitted into a groove 3b formed along a spiral direction on an end surface of a spiral blade 3a of a scroll member without a gap. A space is thus not generated in the groove 3b. By volmetric elastic deformation of the elastic body 18, the chip seal 19 is in sliding press-contact with the side surface of the opposite scroll member. Elastic force is adjusted by forming hole 18a on the elastic body 18 in a direction perpendicular to a longitudinal direction of the groove. The holes 18a concentrate along an outer periphery of the scroll member, while being decreased around the center, so that proper pressing force suitable for position can be generated.

Title: Electromagnetic coupling speaker
Inventor: SHINGO TAKAYUKI
IPC: H04R9/02
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To arrange a coil to be induced in a proper space inside a magnetic gap by easily bonding acoustic radiating elements at proper positions by supporting and fixing the elements on a yoke through gell-state adhesive object having flexibility and surface viscosity. SOLUTION: An element 11 and the upper part of a pole 1 are fixed by an elastic object 16. Since the elastic object 16 has flexibility and surface viscosity, by interposing the elastic object 16, the element 11 and the pole 1 are adhered and the positions of both the element and the pole can be surely held. Besides, the adhesion due to the elastic object 16 eliminates difficulty in comparison with the conventional fixing method, and the element can be easily bonded at the proper position. Thus, the acoustic radiation area of a speaker is not decreased by the increase of adhering area in plane direction and the element is not adhesively fixed only around a hole so that the position can not be deviated in the plane direction. Therefore, the acoustic action is neither limited nor troubled. Further, the speaker having satisfactory acoustic output characteristics can be provided.
