Title: Double balanced mixer circuit
Inventor: TSUJI MASATOSHI
IPC: H03D7/14
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To increase a dynamic range of an output signal and to allow the double balanced mixer circuit not to be affected by ambient temperature and dispersion in its components by configuring the double balanced mixer circuit with a current mirror circuit section that provides an output of a current difference of two output currents from a double balanced mixing section and an output circuit section. SOLUTION: Output currents i1, i2 from the double balanced mixing section 1 are given to a current mirror circuit 2, and the current mirror circuit 2 outputs a current difference between the current i1 flowing through a transistor(TR) Q11 and a current i2 flowing to a TR Q12 to an output circuit section 3. The current difference is given to a series circuit consisting of a resistor R3 and a DC constant voltage source B5 in the output circuit section 3, resulting that a result of mixing a value of a signal source S1 and a value of a signal source S2 is obtained at an output terminal OUT as a current signal. Thus, a dynamic range of the output signal of the double balanced mixer circuit is increased and the effect of ambient temperature and dispersion in the circuit components on the double balanced mixer circuit can be avoided.

IPC: G10H1/34
Filed: 1989-12-08
Abstract: PURPOSE:To enable performance which is rich in expression power according to key operation by contracting a bellows upper part above a bellows support part when a key arranged rotatably on a key support part is pressed down and detecting the displacement of a bellows lower part below the support part when the bellows lower part is displaced. CONSTITUTION:The bellows 11 corresponding to keys 23 supported by the key support part are arranged below the keys and at least the lower part of each bellows 11 is put in a bellows case 28. When the bellows 11 is mounted in the bellows case 28, a nearly closed space is formed at each bellows lower part and a sensor consisting of a photocoupler 27 as a detecting means for the displacement of the bellows lower part is arranged below the space. Therefore, when a key 23 is pressed down, the upper part of the bellows 11 contracts and the pressure in the bellows rises, so that the bellows lower part expands. The displacement of the bellows lower part is detected to detect the touch of the key. Consequently, a musical sound which is generated can be varied with rich expression according to the touch.

When an exciting current is applied to take-out lines 19 of the superconductive coils 15a, 15b, a magnetic flux generated from the coils 15a,15b passes the space in the cylindrical body 12a-hollow part in the measuring pipe 11-space in the cylindrical body 12b, and further a lid body 16b-inside the cylindrical body 12b-measuring pipe 11-inside the cylindrical body 12a-cylindrical body 12a to be returned to the space in the cylindrical body 12a. At this time, a part of the magnetic flux leaking outside is interrupted by the diamagnetic action of a superconductive material 17. Therefore, a signal voltage proportional to the fluid or flow velocity can be taken out from a pair of electrodes 18a,18b with high sensitivity.

Title: Detection of end point of development
Inventor: MOMOSE TAKAAKI
IPC: G03C5/00
Filed: 1987-12-17
Abstract: PURPOSE:To form a minute contact hole in high yields by forming a layer containing a luminescence material on a layer being processed and covering it with a resist layer, by exposing and developing the resist layer and making a hole, and by confirming the exposure of the layer containing a luminescence material at the position and dry-etching. CONSTITUTION:A luminescence material contained layer 16 is disposed between a layer to he processed 12 and a resist layer 15 since the presence of a residue resist on the bottom of a minute hole of a hole diameter of about 1mum produced on a resists layer by an exposure and development process cannot he observed accurately by an ordinary observation under a microscope. This enables the presence of residue resist on the bottom of a hole 17 to be checked visually. Since this makes the bottom of a hole emit light by the light used under a microscopic check, residue resist at the position which a contact hole is formed can be detected by the presence or absence of light emission.

Title: Electrophotographic copying device
Inventor: KURAHASHI HIDEYUKI
IPC: G03G15/04
Filed: 1987-12-17
Abstract: PURPOSE:To prevent toner from being stuck to a copying sheet by holding a white-colored diffusion board in a position which interrupts a lighting optical path at the lower part of an original scanning direction edge reference position when the original exposure scanning is started, and retracting the white-colored diffusion board from the lighting optical path just after the original exposure scanning is started. CONSTITUTION:The white-colored diffusion board 60 is held in the position which interrupts the lighting optical path at the lower part of the scanning direction reference position P of the original 90 which is placed on an original plate glass 70 at least when the exposure of the original 90 is started. Consequently, light which projects the reference position P when the exposure is started is reflected on the white-colored diffusion board 60, and exposes an electrostatic latent image carrier. The white-colored diffusion board 60 is retracted from the illuminating optical path just after the original 90 exposure scanning is started, and an illuminated light is reflected on the edging part of the original 90 which is placed on the original platen glass 70, and the electrostatic latent image carrier is exposed. Thus the toner sticking to the edging part and to the inside part of the copying sheet is prevented.

IPC: G08B21/00
Filed: 1987-12-19
Abstract: The invention describes a method and apparatus for the acoustic signalling of cases of drowning in swimming pools, to guarantee reliable trigger of the alarm while avoiding any false alarms. This is effected basically by a switching element (1) in a water-tight encapsulation, which is disposed beneath the surface of the water and which, in the event of an alarm, triggers a first alarm device (2) and delivers an acoustic signal via a signal horn (5). A transmitter (6) is also connected to the alarm device (2) and transmits the alarm signal to a receiver at a distance and to another alarm device (10). Instead of the switching element (1), a microphone (12) can advantageously be used for cases in which the swimming pool water is frozen.

Filed: 1990-11-22
Abstract: PURPOSE:To shorten the time required for communication of picture information by temporarily stopping the transmission of the picture information when the quantity of the picture information accumulated in an image memory increases and attains a 1st level, then restarting the communication when the quantity decreases to a 2nd level. CONSTITUTION:The picture information received in a signal reception station is received by an picture information receiving means 31 and is accumulated into the image memory 12. A means 33 for detecting the residual quantity of the 1st memory temporarily stops the reading of an original 100 by a reading means 21 and the transmission of the picture information by an picture information transmitting means 22 and further energizes a NULL transmission means 24 upon detection that the quantity of the picture information accumulated in the memory 12 attains the 1st level of the total storage capacity of the memory 12. The transmission of the picture information to a signal transmission station is restarted when the quantity of the picture information accumulated in the memory 12 is decided to be below the 2nd level by a means 36 for detecting the residual quantity of the 2nd memory. The shorter time for the communication of the picture information is necessitated in this way.

Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To release the braking force of a parking brake for a hydraulic motor for travel when a digging operation is done by a working device with a vehicle stopped. SOLUTION: When pilot pressure is supplied to a directional control valve 33 to operate an arm cylinder 9A during the work of digging soil or the like using a working device, the pilot pressure is then supplied to the brake releasing chamber 24B of a parking brake 24 through a working-side brake release pressure supply line 39 and a brake line 40 or the like to release the braking force of the parking brake 24 for a hydraulic motor 12. Thus, even if horizontal digging work is done with a vehicle stopped, for example, the application of great load to the parking brake 24 due to the reaction to digging can be prevented, and the durability and longevity of the parking brake 24 can be enhanced.
