Title: Thread running device of sewing machine
Inventor: HAYASHI MINORU
IPC: D05B53/00
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To run a thread through a needle and hook a thread on a needle bar thread guide concurrently and thereby improve an ease of operation. SOLUTION: A specified thread running operation can be performed by arranging a thread M1, no the end side of this thread running device, which is hooked across thread hooking member 12, at the opposite side of a thread running hook 11b holding the needle of a stitching needle 6, by the transfer of the thread hooking member 12 to be interlocked with the rotation of a thread running shaft 7. At the same time, the thread guiding-in end part 5a of a needle bar thread guide 5 is arranged within the transfer track of a thread M2 of an upstream side oriented toward the thread running shaft 7 side by the thread hooking member 12, by transferring the thread M2.  Thus, it is possible to hook the thread M2 on the needle bar thread guide 5 by allowing the thread M2 to find its way into the back side of its transfer direction in the thread guiding-in end part 5a by causing the thread M2 to ride over the thread guiding-in end part 5a.

Title: Pulse communication equipment
IPC: H04J3/00
Filed: 1992-02-12
Abstract: PURPOSE:To provide the pulse communication equipment which can multiplex sub signals to main signals and can transmit them without degrading the main signals. CONSTITUTION:In a transmission circuit 21, a switch 3 changes over outputs Sm and Sn from the two kinds of multi-level (M and N) PPM modulation circuits 1 and 2, which simultaneously perform the PPM modulation of main signals So, corresponding to the logical level of sub signals Ss. As this switched result, transmitting signals St of the multi-level PPM signals are transmitted from a transmission line 11. In a reception circuit 22, a received sub signal Ssr is reproduced from a received signal Sr from the transmission line 11 by a low-pass filter 7. Multi-level (M and N) PPM demodulation circuits 4 and 5 simultaneously demodulate the received signals Sr at timing prepared by a timing reproducing circuit 9. Based on the level of the received sub signal Ssr, a switch control circuit 6 controls the changeover of a switch 8 and as the result, a received main signal Sor is obtained from any one of multi-level demodulation circuits 4 and 5.

Filed: 1980-02-29
Abstract: PURPOSE:To maintain the interval of bonded wires in a semiconductor device constantly even at a chip corner by setting the interval of the bonded pads on a semiconductor chip to geometric or arithmetic series. CONSTITUTION:Assuming that the interval of bonded pads in a semiconductor chip 13 is represented by b0, b1, b2,..., bn, the interval bn is set to geometric progression represented by bn=b0+na or arithmetic progression represented by bn=b0r<n-1>, (where a>0 and r>1 as constants). Thus, the interval bn of the pads is small at the center of the sides of the chip, and at maximum at the corner. When external leads are accordingly connected to the bonded wires 15, 15', the interval d' of the bonded wires does not become small even at the corner. Therefore, no trouble occurs in the operation of the bonding capillary.

Title: Control method of engine with supercharger
Inventor: YOSHIOKA MAMORU
IPC: F02B37/007
Filed: 1990-02-06
Abstract: PURPOSE:To properly prevent overrun of a turbocharger and prevent abnormal increase in the inlet pressure of the turbine of the turbocharger by forcibly opening an exhaust switching valve at a racing time of no-load. CONSTITUTION:A gear position signal 36 and a clutch signal 38, or an engine rotational speed increase rate signal and the like are inputted in an ECU 29 and it is detected 81 and judged 82 whether an engine is at a racing time of no-load or not, and an exhaust switching valve 18 is forcibly opened at the racing time of no-load. Exhaust gas is also forcibly guided to flow to a stopping side turbocharger 8(auxiliary turbocharger), and since exhaust gas quantity to normally operating(main) turbocharger 7 which operates in a condition of one turbocharger is decreased, overrun of the main turbocharger 7 is prevented. Since the exhaust gas flows to both turbochargers, over-increase in inlet pressure of the turbocharger can be prevented.

Abstract: PURPOSE:To quickly heat up a low resistant material by means of a simple device by inserting a material to be heated up into a part of the resonance circuit for high frequency current, and thereby heating the material by the loss incurred at the section owing to high amperage current flowing in the resonance circuit. CONSTITUTION:When high frequency voltage is applied from a high frequency power supply 1 to the resonance circuit composed of an inductance L and a capacity C in order to be applied to a L and C circuit 5, current will be minimum at time when flowing current is tuned to the applied frequency so that current flowing to an inductive coil 4 will be Q times as much as original one. Owing to the value Q=C/R determined by the constant of the aforesaid closed circuit, when Q is large, high amperage current in the closed circuit will be maximum. The closed circuit is made to be a heating device with a cooling effect, which is formed out of a cooling water inlet port 8, a cooling water outlet port 9, pressure contact terminals 5 and a rubber hose 7. A heating member 6 is arranged between the terminals 5 of the device so that quick heating is thereby effected by high amperage current in the closed circuit by means of a simple heating device.

IPC: G09F9/30
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To provide an image displaying method capable of restricting unevenness of light emission due to the dispersion of the lifetime of luminance of a light emitting element, capable of prolonging the lifetime of luminance of the light emitting element and capable of displaying images of high quality by displaying while reversing the negative/positive display of image continuously displayed fixedly at a predetermined position with a predetermined cycle. SOLUTION: In the negative/positive reverse display by an image display device, an image to be lighted for a long time (for example, letters of FM) is displayed while switching the display between a negative display A and a positive display B with the predetermined cycle. At the time of displaying with the image display device while displacing the display position, an image to be lighted for a long time (for example, letters of FM) is displayed while switching display between a normal display position C and a display position D displaced from the normal position by several dots with the predetermined cycle. With this structure, a light emitting element to be continuously lighted for a longtime is eliminated, and lifetime of the light emitting element can be prolonged. Furthermore, unevenness of the light emission due to an image sticking phenomenon is reduced.

Title: Production of alexandrite single crystal
Inventor: HIROSE TOSHIYUKI
IPC: C30B29/22
Filed: 1985-02-14
Abstract: PURPOSE:To obtain alexandrite having uniform color and free from foreign materials such as bubbles, by using organic compounds as the starting raw materials of Al2O3 used as a main component and Cr2O3 and Fe2O3 used as additives. CONSTITUTION:A rod-shaped sintered material composed of nearly equimolar amounts of Al2O3 and BeO and added with small amounts of Cr2O3 and Fe2O3 is used as a raw material. Infrared radiation generated from a halogen lamp is focused to the rod with a spheroidal mirror, and the focused beam is moved to melt the raw material at one interface of the molten zone, and to effect the crystal growth on a seed crystal at the other interface. In the above process, an organic aluminum compound is used as the starting raw material of Al2O3 used as the raw material, and an organic material is used as the starting raw material of Cr2O3 and Fe2O3 used as additives. An alexandrite single crystal having uniform color and free from foreign materials such as bubbles can be produced by this process. When the alpha-axis of the seed crystal is aligned to the direction of the crystal growth, the drop of the molten liquid is prevented even by the abrupt change in the power of the halogen lamp, and a single crystal can be produced with simple process control. Furthermore, the quality and productivity of the crystal can be improved.
