Title: Handset
Inventor: UMEOKA KAZUAKI
IPC: H04M1/03
Filed: 1987-02-24
Abstract: PURPOSE:To attain the talking not affected by noise at talking under noise by fitting a tubular silencer element limiting the channel band of a sound wave at least to one of a mouth piece and an ear piece of a handset main body. CONSTITUTION:A silencer element 4 is a double tube using a hollow pipe and an inner pipe and an outer pipe 7 at the outer circumference via a space part 8, and the element 4 is arranged to the mouthpiece 2 and the ear piece 3 of the handset main body 1. When a sound wave is propagated in the hollow pipe 5 made of a viscoelastic body as the inner pipe 6 whose both ends are opened, the vibration mode vibrating in a face orthogonal to the tube axis is caused to the tube wall. When a frequency close to a resonance frequency fr passes in the hollow tube 5, a minute part DELTAx is resonated and the vibrating mode shown in arrows is generated and the sound wave in the tube 5 due to hysteresis loss of the tube wall is attenuated rapidly. Thus, in setting properly the passing frequency of the element 4, only the voice band is propagated and undesired noise is eliminated.

Filed: 1990-02-23
Abstract: PURPOSE:To make it possible to process accuracy in a cut face in a micron order against a standard pattern by performing finishing of the cut face with a highly rigid grindstone and cutting in a block shape while accuracy of the standard pattern on a wafer is kept. CONSTITUTION:The first line of an element pattern of a wafer 1 is measured by means of a microscopic system and positional adjustment using this as a standard is performed by rotating an XYtheta table 7 in such a way that the main axis and a standard element pattern are vertically crossed. Then, faces of unnecessary parts 2 of the front of the first line of the standard element pattern and both sides thereof are cut by using a cutting grindstone 4 for cutting wafer vertically to the first line of the standard element pattern to remove the unnecessary parts. Then, positioning of the wafer 1 is done by means of the microscopic system 3 and the XYtheta table 7 and surface finishing of the front cut face of the first line of the standard element pattern is performed by a grindstone 5 for surface finishing in such a way that curves and strain generated by cutting are corrected. A cut face which is parallel to the standard pattern is thereby formed.

Then, a slide cam 20 comes into slide contact with a drive cam 22, and the cam 20 slide by a specified length in the direction of the pad 8 while compressing and deforming an elastic body 21. Consequently, a fixed clearance for trimming necessary for trimming between an upper edge 17 and a lower edge 6 is secured. When the holder 1 is further lowered, flange up work F is performed by a flange die 3 and the edge part 8a of the pad 8 as usual, and trimming is carried out on the periphery of the part W by shearing action of edges 17, 6 when the holder 1 arrives at the bottom dead center. The clearance between edges 17, 6 is determined only by slide contact of cams 22, 20, and can be kept constant at all times.

Abstract: PURPOSE:To make a noise margin wide and to make usage easy by providing a barrier comprising GaAsSb which matches the lattice of InAs and a resonating tunneling barrier of a well comprising InAs between the emitter and the base of an emitter, a base and a collector comprising InAs. CONSTITUTION:An n<+> emitter E, a p<+> base B and an (n) collector C are pro vided with InAs. A barrier comprising an i-type GaAs0.1Sb0.9 1 which matches the lattice of InAs and a resonating tunneling barrier RB of a well comprising InAs are provided between the E and B.

Title: Dynamic logical encoding method and device
Inventor: ROBAATO EICHI MIRAA
IPC: G11C8/10
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To reduce the loads of signal lines and coupling ability between the signal lines and to reduce signal noises by dividing a plurality of logic paths and performing encoding. SOLUTION: The logic paths are low-order divided (902) into groups composed of the N(N>2) logic paths and the respective groups composed of the N pieces of the logic paths are encoded (904). As a result, by the expression of a prescribed coupling of the N pieces of the logic paths, the prescribed one of 2N signal lines is expressed (906), the simultaneous expression of the two or more of 2N signal lines is defined (908) as invalid and the precharge of the signal lines is made possible (910) by the simultaneous non-expression of all the 2N signal lines. Thus, the encoding of the plural logic paths is made possible by a 1-out-of-2N form.

Filed: 1981-03-25
Abstract: PURPOSE:To prevent troubles due to noises by reducing the induction and radiation of noise components, by putting a pair of double trip wires through plural magnetic rings having a large magnetic loss, and then, by fitting the magnetic rings to the wire at a constant interval of distributed constant. CONSTITUTION:A double trip wire 1 is put through plural magnetic rings 2. The rings 2 are fitted to the whole length of the wire 1 at a constant interval. Then, induction of noises to a line or radiation of noises from the line is greatly restrained. Moreover, since the magnetic loss of the ring 2 is large, amount equivalent to the inductance and resistance equivalent to the magnetic loss are added to the stray capacity of the line in terms of distribution factor, and thus, resonance is restrained.

Title: Controller for electric cleaner
Inventor: YAMAGUCHI SEIJI
IPC: A47L9/28
Filed: 1988-02-24
Abstract: PURPOSE:To require no switching each time by disposing a detecting means for detecting the air quantity in the air passage of a power nozzle and driving a rotating brush automatically when the air quantity reaches a value above a set value. CONSTITUTION:When a cleaner main body is operated, the air is passed to the air passage of the power nozzle. The air quantity is detected by the air quantity detector 13, and then the output is inputted to the inverting terminal of a comparator 17. When the output of the detector 13 exceeds the preset reference voltage, the output of the comparator 17 changes from 'H' to 'L' and the output of a inverter 23 changes from 'L' to 'H'. Accordingly, a transistor 25 is turned on, a trigger signal is passed to a bidirectional thyristor 12 to turn the bidirectional thyristor 12 on, supply power to a driving motor 11 and rotate the rotating brush of the power nozzle. In such a way, the rotating brush of the power nozzle is automatically rotated when the cleaner is operated and the air quantity reaches a value above the preset value. The utilization is improved without operating the switch each time by a user to automatically execute proper cleaning corresponding to the floor surface.

SOLUTION: An expiration A in an expiration collection bag connected to a port 5 flows in a route from ports 5 and 4 to ports 2 and 1 via a collection tube 14 on the operation of a pump 22, and is adsorbed with the collection tube 14 kept approximately at 5 deg.C at a cooling and heating part 16. Subsequently, carrier gas C is made to flow from a flow regulator 341 to a reservation part 18 via a port X, the collection tube 14 and ports 4 and 6 on the operation of a flow passage selection part 32, while keeping the collection tube 14 approximately at 200 deg.C at the cooling and heating part 16. Furthermore, an expiration sample (a) desorbed from the collection tube 14 is condensed and flows together with the carrier gas C for storage in the reservation part 18. This expiration sample (a) is drawn into a sampler body 202 through a detection tube 201.  In this case, a detection agent contained in a detection tube 201 reacts with measurement gas contained in the sample (a), thereby enabling gas concentration to be detected from a discolored layer appearing in the agent.
