Title: Exhaust gas purifying device for internal combustion engine
Inventor: WAKITA NOBUAKI
IPC: F02M25/07
Filed: 1978-03-07
Abstract: PURPOSE: To reduce the exhausted NOx in amount, prevent surging, and lower the fuel consumption by properly regulating the flow rate of air branching from a secondary air supply device to EGR device.  
     CONSTITUTION: Two-staged air flow rate control valve 60 is set between a secondary air supply passage 12a and an exhaust gas flow rate regulation valve 24.

Filed: 1989-02-03
Abstract: PURPOSE:To obtain a required low noise effect by dispersing each frequency component by a method wherein printing timing of a plurality of printing pins to be driven by each output signal is divided into a plurality of parts, and said number of divided parts is set to three or more divided parts. CONSTITUTION:A printing head A is made to be under a printing pin arrangement (left oblique 4 dots X 6 blocks) in which a number of printing pins to be simultaneously driven among the printing pins 1 to 24 to be driven by each output signal is made to be, for instance, three pins, and output timing of printing data is divided into 8 parts. Therefore, a shortest printing interval becomes T/8 for a printing stroke T. Since three printing pins print letters simultaneously in point of time with the thus constructed printing head, a required low noise effect can be obtained by dispersing each frequency component.

IPC: C30B15/28
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To surly obtain a crystal having uniform characteristics. SOLUTION: A crucible for housing a crystal material and a liquid capsule agent is supported by a pushing-up shaft. A seed crystal is supported by a pulling-up shaft in the upper part of the crucible. The crystal material and the liquid capsule agent are melted when the crucible is heated to a prescribed temp. by a heater 9 and the inside of a chamber is maintained in a prescribed environment. The pulling-up shaft is lowered to bring the seed crystal into contact with the molten crystal material. The pulling-up shaft and the pushing-up shaft are rotated to raise the pulling-up shaft at a prescribed pulling-up speed and to rise the crucible at a prescribed pushing-up speed. The pulling-up shaft is hung down in a measuring section 27 for measuring the mass of the crystal. A correcting section 28 calculates the diameter of the crystal from the mass measured by the measuring section 27.  The pushing-up speed is corrected when the calculated value and the preset value do not coincide.

Title: Balancer device in engine-transmission system
Inventor: DOI NOBUO
IPC: F02B67/00
Filed: 1986-02-10
Abstract: PURPOSE:To reduce bending vibrations, by setting a vibromotive force with balancers to work more to a position on which the resultant force of an engine vibromotive force acts than to a position where the amplitude of a bending vibration mode becomes wide. CONSTITUTION:A toothed belt 14 is wound between a toothed pulley 12 which is provided on the output shaft 5 of an engine and a pulley 13 which is provided on a camshaft 18, and a pulley 15 provided with a balancer 11a is rotated integrally via the toothed belt. And a gear 16 is mounted to the pulley 15, and is engaged with the gear 17 of a pulley 22 provided with a balancer 11b, so that the respective balancers 11a, 11b are rotated reversely. These balancers 11a, 11b are rotated at a same speed that is twice as fast as the output shaft 5, and the resultant force of centrifugal forces generated by the rotations of both balancers becomes the vibromotive force of the balancers. As the installing positions of the balancers to the pulleys are made variable, the vibromotive force can be made bigger in case of mounting auxiliary machinery. Thus, the addition or the reduction of the auxiliary machinery can be dealt with, and simultaneously bending vibrations can be reduced.

Abstract: PURPOSE:To eliminate necessity of a carrier oscillating circuit and to improve reliability for a remote controller of an electric device, by converting an optical signal which is converted alternately with two different frequencies into an electric signal, and detecting the frequency at a filter to perform control in phase and a logical process. CONSTITUTION:The infrared rays are irradiated from a light emitting diode as soon as two frequencies f1 and f2 are transmitted alternately from two oscillating circuits of a transmitter 1. A detecting circuit 2 receives the infrared rays and then converts then into an electric signal. This electric signal is amplifyied by an amplifying circuit 3 and then supplies an output to filter circuits 4 and 5 respectively. The circuits 4 and 5 detect the frequencies f1 and f2, and at the same time the demodulation is carried out to supply the output of demodulation to a logical circuit 6. Thus each phase is controlled to obtain an  equal phase, and then a logical operation is performed through an NAND gate  to detect that the signals of frequencies f1 and f2 have a prescribed interval.  Then switching circuits 7 and 8 to be controlled are driven.
