Title: Dds system waveform generator
Inventor: SAWARA MAKOTO
IPC: H03B28/00
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To improve convenience of a DDS system waveform generator by providing an additional circuit so as to provide a pulse generating function excellent in stability and precision of a period and a pulse width. SOLUTION: When a trigger signal is given from a delay means 10 to a flip-flop FF 11 for trigger oscillation and a delay is zero, the FF 11 is set to release clearing of an adder 1, an output of a latch 4 is increased in response to an increase in an output of the adder 1 synchronously with a clock signal, and when the adder 1 reaches a full scale and overflows, an output of the latch 4 is decreased rapidly, a level of an MSB signal transits from H to L to reset the FF 11. Then the FF 11 is held till a succeeding trigger comes, then the FF 11 oscillates a pulse signal synchronously with the trigger. The period of the pulse is set by setting a frequency being a reciprocal of a period T to a frequency setting register 2, and a pulse width W is set by setting a duty ratio D(=W/T) as duty ratio setting data. Thus, the pulse waveform is set without a sense of incongruity.

Title: Nonskid device for tire and manufacture therefor
Inventor: TSUCHIYA KAZUO
IPC: B60C27/16
Filed: 1987-03-03
Abstract: PURPOSE:To prevent the falling off of a spike metal fitting and damage to a tire by said metal fitting by placing both end parts in the circumferential direction of said spike metal fitting on the road face contacting face of a frame body and forming chips in the vicinity of said end parts at the time of installing said metal fitting around said frame body made of an elastic material. CONSTITUTION:A spike metal fitting 38 is caulked into an elliptical shape and installed on nearly the center part in the perpendicularly intersecting direction to the longitudinal direction of a rubber body 30 which is formed by combining a frame body having nearly a rhomboidal plan form with a frame body having nearly a triangular plan form, surrounding the body 30. In this case, both end parts in the circumferential direction of the spike metal fitting 38 are placed on the surface (face on a road face contacting side) of the body 30, and made nearly flush with the surface. And, a pair of chips 44 are fixedly provided in the vicinity of the end parts. By this structure, it is nearly eliminated that the spike metal fitting itself is brought into contact with the ground reducing the wear of the metal fitting and, even if the metal fitting is broken, preventing it from scattering, etc., since the remainder of the metal fitting is held within the body.

IPC: H02M7/48
Filed: 1987-03-05
Abstract: PURPOSE:To prevent a transformer from saturating by detecting a DC component from the AC output of an inverter, and feeding back the result to a main switching circuit. CONSTITUTION:In a PWM type single-phase AC output inverter, a main switching circuit 1 is composed of 4 transistors connected in a bridge to convert a DC input into an AC output. A PWM signal for controlling the circuit 1 is obtained by an operational amplifier 2 from the output of a reference sine wave generator 3 and the output of a triangular wave generator 4. In this case, an operational amplifier 5 and a DC component detector 6 are further added. The signal detected by the detector 6 is calculated by the sine wave and the amplifier 5, compared with the triangular wave to obtain a PWM signal. The circuit 1 is controlled by the PWM signal. Thus, the DC component presented in the AC output can be suppressed.

Inventor: YOSHIKAWA YOSHITSUGU
IPC: F25B11/00
Filed: 1995-02-14
Abstract: PURPOSE: To achieve a reduction in operation cost and equipment costs by converting an excess of power of a gas turbine to electric power by a motor when the power generated by a gas turbine is greater in operating conditions as compared with a necessary power of a compressor. CONSTITUTION: A gas turbine 4 and a synchronous motor 5 doubling an AC power generator as auxiliary motor are linked to a propane compressor 1 which pressurizes two kinds of refrigerants circulating through closed loops independent of each other. A gas turbine 6 and a synchronous motor 7 are linked to two mixed refrigerant compressors 2 and 3 connected in series. In operating conditions under which the power generated by the gas turbines 4 and 6 is larger as compared with the necessary power of the compressors 1-3 in, an excess of power of the gas turbines 4 and 6 is converted to a power by the synchronous motors 5 and 7. This enables spare parts for countering troubles involved in the gas turbines 4 and 6 thereby lowering equipment costs.

Abstract: PURPOSE:To make the recovery of jamming easy and to prevent a transfer paper from being left by providing passage detecting sensors on a lower carrying path and a circulating carrying path, detecting the occurrence of the jamming from the output signals of the sensors and executing a jam display after the completion of a jam processing action. CONSTITUTION:When a transfer paper detecting sensor PS4, PS5, PS3 or PS11 detects the presence of the transfer paper, a both-side motor 40 is driven over a time that the transfer paper is carried by a distance from the sensor PS3 to a both-side paper ejection roller 30. When an electromagnetic clutch 39C is tuned on, the transfer paper is fed to a both-side tray 31 by pairs of rollers 29 and 30 and 52. After that, a CPU displays the occurrence of the jam on a display provided on an operational plate. At this time, a place where the jam processing is required is shown on the display. The transfer paper remaining on the carrying path at the time of jamming can be stacked in the both-side tray 31 and normally it can guide the leading edge of the transfer paper intruded from the lower carrying path 15.

Abstract: PURPOSE:To enable a grinding material to move in quick response at the time of restarting immediately after emergency stop in the line in such a way that when coating film on the automobile body, etc. is ground by pushing a grinding material with use of a weight, negative pressure is produced as the grinding material takes shelter into the lower chamber of a shelter cylinder. CONSTITUTION:When emergency stop is involved in the line, an air cylinder 20 extends a roller support 19, a roller arm 15 turns against a thrust weight 17, and support arm 3 turns a support shaft 4 to make a grinding material 5 to retreat. In the meantime, an arm 29 turns, a piston 27 is forced upward, and negative pressure is produced in the lower chamber of a hydraulic cylinder 24. Immediately after emergency stop, when operation is resumed, the air cylinder 20 contracts the roller support 19, connection of the support arm 3 and an arm support shaft 8 is released, the grinding material 5 is pushed to the automobile body W by working force of the thrust weight 17 when grinding starts up. On the other hand, negative pressure in the lower chamber of the hydraulic cylinder 24 sucks the piston 27 downward, to assist in quickening responding action of the grinding material 5.

IPC: B60W10/103
Filed: 1986-03-06
Abstract: PURPOSE:To make it possible to make the restart of a vehicle smooth, by detecting the operating condition of a clutch to feed back the thus detected value for speed change control in order to promote the speed change operation when the clutch is disengaged during deceleration of the vehicle. CONSTITUTION:A hydraulic type continuously variable transmission T is composed of a hydraulic pump 2 and a hydraulic motor 4 which are connected in a closed circuit 5. When an opening degree of a clutch valve 7 in a short circuit 6 exceeds a predetermined value, a discharge hydraulic pressure Pl is applied to a spool 127 in a pilot valve 117, instead of a throttle valve hydraulic pressure Pt to move a piston 113 rightward to minimize the speed ratio (e). Accordingly, the speed change operation becomes fast in association with the disengaging operation of the clutch during abrupt stop of the vehicle, and the speed ratio is rapidly decreased, thereby it is possible to make the start of the vehicle smooth.
