Patent JP-2000308383-A (JP)
Title: Inverter
Inventor: UENO SACHIO
IPC: H02P21/24
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To reduce the fifth and seventh time harmonies that contribute to vibration in the maximum degree to realize low vibration and low noise motor operation by determining the power feeding angle to the particular range. SOLUTION: A motor that is connected in three phases by deviating the phases for 120 deg., for example, with one period of space defined as 360 deg. is operated with the 3-phase voltage (U-phase voltage, V-phase voltage, W-phase voltage) having a phase difference of 120 deg. with one period of application voltage defined as 360 deg.. In this case, in the fifth and seventh harmonics that contribute to vibration in the maximum extent, the power feeding angle is obtained from A of the phase angle where the fifth and seventh harmonics becomes 0 at the rise point of the rectangular waveform. The fact that these harmonics are 0 means that a vibrating force is 0 and any vibration is not generated.  Namely, the fifth and seventh time harmonics are minimized by setting the power feeding angles to 144 deg.±3 deg. to 154 deg.±3 deg. or 149 deg.±3 deg. with fluctuation of about 3o defined as the allowable range. As a result, the fifth and seventh time harmonics can be minimized to realize the low vibration and low noise motor operation.

Title: Microphone for telephone sound recording
Inventor: TAKEDA YUKIO
IPC: H04R1/46
Filed: 1985-05-23
Abstract: PURPOSE:To collect a sound only from a receiver faithfully and to transmit the sound from the receiver to an ear efficiently by providing a shield body which has through holes to the rear part of a close-talking microphone unit which has an opening for characteristic adjustment in its rear surface, and arranging them so that the distance between the opening and through holes is as long as possible. CONSTITUTION:A concha insertion holder 8 which has an ear pad 10 and serves as the shield body is inserted into a concha and a receiver is applied to the ear while superposed on a main device. The outward size of a microphone unit case 2 is small, so the voice of the receiver leaks from its periphery and is transmitted to the ear hole from the through holes 8' provided to the concha insertion holder 8 and sound pressure is applied from the front sound hole 3' of the front plate 3 of the case to the close-talking microphone unit 1 at the same time, so that a generated signal current is outputted from an input/output plug 11 and recorded. The talking voice of a person who puts on this device is received by the transmitter of a telephone set and reproduced through the receiver, so both conversation voices are recorded. At this time, the quantity of voice collection of space voice of said person's voice is extremely small not to mention ambient noises, noises because of close-talking characteristics of the microphone unit 1 and bone-conducted voice is reproduced by a partition plate 9, so that the voice of the person who puts on the device can be recorded clearly.

Abstract: PROBLEM TO BE SOLVED: To eliminate cracks in a die and to improve productivity and quality by using, for the upper die, a hot rolled steel formed with a cladding layer of a weld hardening material on the surface and using, for the lower die, a hot rolled steel in a manner that the end of a workpiece is untouched by the lower die. SOLUTION: The lower die 10 is such that it is constituted of rolled steel, that the steel hot-rolled into a cylindrical shape is bi-sected vertically, that one of the bi-sected steel members 11 is provided with a groove 12 for a die holding key on the end face at prescribed spaces apart, and that a pipe transporting roll hole 13 is made in the center of the circumferential face at prescribed spaces apart. A rolled steel of S45C is used for the lower die 10 for the purpose of preventing cracks. Since the rolled steel is used for the lower die which is not in contact with the edge of the pipe, the surface of the die is free from scraping and, therefore, from scratches due to the edge of the pipe at the time of press working. The upper die is made of a rolled steel and provided with a cladding layer of a weld hardening material on the part which comes into contact with the workpiece.

Inventor: NEMOTO HIROYUKI
IPC: C03C21/00
Filed: 1992-04-30
Abstract: PURPOSE:To provide the glass substrate, such as glass substrate for liquid crystal cells or glass substrate for semiconductors, useful for such applications where the elution of alkaline components from the inside of the glass is generally of a problem. CONSTITUTION:The glass substrate 1 consists of soda lime glass contg. alkaline components, such as sodium oxide and potassium oxide. The alkaline ions, such as Na ions and K ions, in the glass are substd. with the ions of the ion radii larger than the ion radii of these ions, for example, Ti ions, in the layer 2 down to a specified depth from the surface of the glass substrate 11 over the entire surface thereof. Namely, the glass compsn. of the part of the surface layer 2 is reformed to the compsn. substantially free from alkaline components. The film for preventing the elution of the alkalis free from pinholing and peeling is formed by the inexpensive method. The use of silicate glass and soda lime glass which have heretofore been unusable as the glass substrates for liquid crystals and semiconductor glass substrates, in this application is thus made possible.

Title: Data processor, method for processing band of the same and storage medium storing computer readable program
Inventor: HORIIKE TOKUKAZU
IPC: B41J5/30
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To reduce the overhead time of records and to select a proper band height by referring to respective registered tables and deciding the band height for banding-processing a plotting command. SOLUTION: A band memory generating part 105 temporarily sets a plurality of band heights for developing the bands concerning a band memory. A plurality of tables (band crossing tables generated by the part 105) store the number of the plotting commands over a plurality of bands by every temporarily set band height. The part 105 judges whether the plotting range of the received plotting commands extends over the temporarily set bands or not. The part 105 registers the number of the plotting commands over the bands, refers to each registered table and, then, decides the band height for banding-processing the plotting commands.

Abstract: PURPOSE:To efficiently scrape garbage such as wet refuse adhered to a peripheral wall inner face by clamping a blade to a window of a cover component to be covered on a strainer, energizing the blade by an elastic component, pressing the same to the peripheral wall inner face and retaining thereon. CONSTITUTION:Wet refuse produced in a sink 10 of a sink stand is discharged from a drainage hole 10a to a disposer 11 together with water, and then flowed from a drainage pipe 12 into a strainer 16 of a garbage disposal device 13. A centrifugal force is applied to the wet refuse by driving a motor 17 and rotating the strainer 16 at a high speed to make the wet refuse adhered to a peripheral wall inner face 16a of the strainer 16. Dehydrated water is drained outside by passing from a strainer storage chamber 15 through a drainage line 19. Further the wet refuse after dehydration is scraped by an edge of a blade 30 energized elastically and pushed up. Then the wet refuse is recovered from a recovering passage 20 into a recovering chamber 22. The wet refuse adhered to the peripheral wall inner face 16a of the strainer 16 can be scraped off efficiently by the arrangement.

Title: Flow controlling device of working fluid for power steering
Inventor: NARUMI TADATAKA
IPC: F15B9/08
Filed: 1979-08-31
Abstract: PURPOSE: To prevent flow from return in pressure operation of a power steering apparatus by closing controllably one of two throttle paths arranged in parallel according to the rise of rotational frequency of a pump irrespective of displacement of a spool valve for adjusting flow.  
     CONSTITUTION: When a pump rotor is rotated by an engine, pressurized oil is supplied from a pressure chamber 16 to a power steering apparatus 24 through a supply path 14, first and second throttle paths 26, 29 and an exhaust port 23. When the rotational speed of the pump is low, a spool valve 17 closes a bypass path 15 with low discharge amount to send total amount of pressurized oil to the apparatus 24. Next, when the discharge flow increases as the rotational frequency of the pump rises, the spool valve 17 slides to maintain differential pressure before and after the throttle paths 26, 29 at a constant value and thereby open the bypass path 15. Further increase of the discharge flow of the pump displaces a control spool 35 according to the differential pressure between the chambers 16, 18 to close the throttle path 29.
