Title: Ringer circuit
Inventor: KITAMURA TOMOYOSHI
IPC: H02M7/48
Filed: 1989-06-29
Abstract: PURPOSE:To simplify the circuit constitution and control by driving a semiconductor switch with a digital pulse so as to send sinusoidal wave ringer power. CONSTITUTION:A drive pulse generating circuit control section 12 receives a clock pulse from a clock pulse generator 13 and sends a synchronizing pulse to synchronize a pulse from a PWM pulse generating circuit 14 and a rectangular wave pulse generating circuit 15. When the rectangular wave pulse generating circuit 15 of the semiconductor switch drive circuit 11 receives the synchronizing pulse, the circuit 15 generates a rectangular wave pulse being ON for a half period for each half period interval of a sinusoidal wave and a rectangular wave pulse being ON when the rectangular pulse is OFF synchronously with the PWM pulse generated by the PWM pulse generating circuit 14. Then transistors(TRs) Q2 and Q3 are driven by driver circuits 17, 18 respectively. Thus, the control to obtain the sinusoidal wave output waveform is easy and the small size circuit is obtained.

Title: Manufacture of stainless steel-aluminum clad plate
Inventor: HARA KENJI
IPC: B32B15/01
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To obtain the stainless steel.aluminum clad plate which is superior in its jointed strength, without applying a polishing treatment with a wire brush but by making the rolled jointing of the stainless steel and the aluminum plate. The surface of the stainless steel is finished either by an acid cleaning treatment with mixed acid of nitric acid and fluorine acid or by an electrolytic pickling with nitric acid. SOLUTION: A jointability is increased because a composition of oxidated membrances of steels are of the same even when the steel is treated either with an acid cleaning of a mixed acid of nitric acid and fluorine acid, or with an electrolytic pickling or a wire brush treatment. An observation of an oxidated membrance of SUS430, a surface of which is polished with a wire brush and then heated, reveals that a composition of the outer layer is Fe2 O3 and the inner layer is Cr2 O3 substantially, according to the conventional method. Since the Cr2 O3 of the inner layer is hard in ductility, an oxidated membrance is easily destroyed at a cutting procession of the rolled jointing, and a basis material of the stainless steel, which is to be called a newly boron face, is easily exposed. Jointability with an aluminum at the jointing interface is then presumed to be increased.

IPC: B60J1/00
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To prevent the malfunction of a foreign material catch preventing function due to the temporary fluctuation of power voltage without any delay in timing for detecting a catch state or any increase in a detection load. SOLUTION: A motor 1 causes the reciprocating motion of window glass, according to an instruction from a control circuit 4. A shunt resistor 3 outputs a voltage signal Vd at such a level as corresponding to the load current of the motor 1 via an amplifier 5. Also, an A-D conversion circuit 10 outputs a voltage signal Vs to show the power voltage level of the motor 1. Also, the control circuit 4 reverses the travel direction of the window glass during the travel thereof toward a closing direction, when the increment of the load current per unit time shown by the voltage signal Vd is equal to or above a threshold value. Furthermore, the control circuit 4 is changed over to a compensation operation mode, when the level of the voltage signal Vs drops by an amount equal to or more than the prescribed voltage range.  At the same time, the control circuit 4 in the compensation operation mode adds the preset current correction value to the threshold value, upon the detection of the rising tendency of the voltage signal Vs by an amount equal to or above the prescribed level.

When a pressure in the vicinity of a throttle valve 7 in an intake-air passage within a range of low or intermediate engine load becomes high vacuum pressure, a purge control valve 10 opens to establish the communication of an evaporated fuel feed passage g'. Thereby, pressure in an exhaust passage 14 is applied to the storage chamber 4 through a check valve 15 when it become negative pressure due to exhaust gas pulsation, so that the absorbed evaporated fuel is introduced into the exhaust passage 14 through the feed passage 9' together with the atmospheric air which has passed through a filter material 12. Further, the evaporated fuel is transferred to an exhaust purifying device 13 together with high temperature exhaust gas, and is burnt by the atmospheric air which is fed together with the evaporated fuel. Thereby, the operationability and exhaust gas characteristics of the engine is remarkably enhanced.

Filed: 1982-09-30
Abstract: PURPOSE:To enable adequate detection of foreign metal contained in a product by adding detection signals pertaining to the product at an adequate ratio to cancel among those detection signals from a synchronous detection in two phases. CONSTITUTION:As a product mixed with iron passes, a detection signal Fe+H (alpha) in (d) is obtained from a synchronous detector 16a, which previously lowered the detection sensitivity.

Abstract: PROBLEM TO BE SOLVED: To provide a system which does not require a large capacity of buffer circuit and complicated timing control by dividing a data signal from a terminal into blocks shorter than a communication slot, dividing the block into (n)-pieces of division blocks and arranging them in parallel. SOLUTION: An information terminal 110 transfers the data signal at 64kb/s being the transmission speed of the communication channel of a cable digital network with a moving terminal 101. The moving terminal 101 requests the use of two communication channels at 32kb/s and a base station 102 correspondingly sets the two communication channels 107 and 108 for the moving terminal 101. The moving terminal 101 divides the data signal received from the information terminal 110 into the two communication channel signals and they are transmitted to the base station 192 by the communication channels 107 and 108. The moving terminal 101 synthesizes the signals received in the two communication channels 107 and 108 into one signal of 64kb/s and transmits it to the information terminal 110.
