Title: Magnetic recording device
Inventor: KONDOU TAKASHI
IPC: G11B15/473
Filed: 1983-05-23
Abstract: PURPOSE:To record magnetically only an audio signal by providing a pseudo synchronizing signal generating circuit, and putting a servo circuit in normal operation on the basis of a pseudo synchronizing signal even when no video signal is inputted. CONSTITUTION:The pseudo synchronizing signal generating circuit is shown by 11 and generates the pseudo synchronizing signal equivalent to a vertical synchronizing signal. When no video signal is inputted to a terminal 2 while the audio signal is inputted to a terminal 1, a synchronizing signal detecting circuit 12 detects no synchronizing signal, so a switch 13 is so operated as to lead the pseudo synchronizing signal from the pseudo synchronizing signal generating circuit 11 to the servo circuit 9. Consequently, the servo circuit 9 outputs a drum driving signal on the basis of the pseudo synchronizing signal, so the rotation of a drum 7 is controlled and the video signal is inputted to the terminal 2, so that tracking is performed during reproduction. At this time, no video signal is inputted, so only the audio signal is recorded on a magnetic tape as a recording signal.

Title: Picture recording device
Inventor: KAWAGUCHI BUNROU
IPC: H04N1/405
Filed: 1984-05-09
Abstract: PURPOSE:To reduce both the space and the cost by using the same image frame memory and line memory to perform silver salt and non-silver salt recording and therefore giving both silver salt and non-silver salt recording functions to a sin- gle picture recording device. CONSTITUTION:In a silver salt recording mode, the input picture signals equivalent to a picture element recorded on four picture elements of main scan direction are recorded on eight continuous picture elements of a line memory 5 respectively. Thus the picture signals equivalent to a line on an image frame memory 3 are all written in the memory 5. Then silver salt picture signals are sent to a picture recording part 8 via a D/A converter 7 and recorded on a silver salt sensitive material. In a non-silver salt recording mode, the gradation of the input picture signals stored in the memory 3 is simply compressed at a central processing part 4. Then the picture signals within the memory 3 are binary- coded into ON/OFF signals and applied to the memory 5. Then these binary- coded picture signals are sent to the part 8 via the converter 7 and recorded on a non-silver salt sensitive material.

IPC: F02D41/22
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent black smoke from occurring, by controlling fuel amount not to cause stagnation of rotational frequency of a diesel engine. SOLUTION: An electronic governor 2 generates a fuel supplying control signal from a rotational frequency real signal and an instruction signal of an engine 1, and outputs it to a black smoke controlling device 4. The rotational frequency real signal of the engine 1 enters into the black smoke controlling device 4, limit value of fuel supplying amount corresponding to the rotational frequency is calculated from data in a memory, and a pulse adding calculator 13 adds pulse to it. The fuel supplying control signal of the electronic governor and the pulse added limiting signal are compared in a two-signal comparing part 15, and smaller one is added to a governor actuator B of the engine.  Even if some fuel supplying amount controlling signal exceeds a fuel supplying amount limit value line, when pulse is added to the fuel supplying amount limit signal, this pulse automatically moderates the fuel supplying amount limit value, and therefore, the rotational frequency is stimulated to increase and the rotational frequency of the engine increases.

Title: Level gauge
IPC: G01F23/22
Filed: 1992-03-17
Abstract: PURPOSE:To obtain a level gauge having a small size and good responsiveness by using a superconducting material having a phase transition starting temperature higher than the temperature of a liquid and phase transition ending temperature lower than the for the detecting element section of the gauge. CONSTITUTION:By connecting a power source 4 to the superconducting film 3 of a detecting element section 1, the film is directly made to generate heat by making a constant current to flow to the film 3 and, at the same time, the surface level of a liquid is detected as a voltage change by means of a voltmeter 5. Since the part of the film 3 above the surface level of the liquid is always in a normal conducting state while the part of the film 3 in the liquid is in a superconducting state due to a liquefied gas, the surface level of the liquid can be detected from a voltage drop caused by the resistance of the part of the film 3 above the surface level of the liquid. Since the title level gauge is constituted in such a way that a superconducting material having a phase transition starting temperature higher than the temperature of the liquid and phase transition ending temperature lower than the temperature is used for the section 1 and the superconducting material itself can also be used as a heat generating body. the manufacturing process can be simplified and the element can be miniaturized and, since the superconducting material itself is directly heated, the responsiveness of the level gauge is improved.

Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To calculate accurately fuel injection amount of each air cylinder for two-cylinder engine using an output signal from an intake pressure sensor. SOLUTION: Intake manifolds on both air cylinders of two-cylinder engine are communicated each other through a communicating pipe, an intake pressure sensor is installed on the way of this communicating pipe, and average intake pressure of both cylinders is detected.

When fuel injection amount of the second cylinder is calculated, standard injection time TP2 of the second cylinder is calculated based on different pressure (Pa-P1) of bottom pressure P1 of average intake pressure which decreases according to an intake process on the first cylinder side and atmospheric pressure Pa, and engine speed NE (steps 105, 106).

Title: Electromagnetically driven shutter
Inventor: HIROHATA MICHIROU
IPC: G03B13/36
Filed: 1981-06-15
Abstract: PURPOSE:To make opening of blade members sure by retreating a tightening lever which starts automatic focusing operation from the operating region of a member generating electromagnetic driving force after controlling the focusing operation. CONSTITUTION:Upon ending of automatic focusing operation, a control circuit supplies electricity again to a coil 1 to turn a rotor 2 clockwise, but this gives no influence upon a tightening lever 11. At this time, a sector ring 4 is driven by the turning of the rotor 2 and turns clockwise, thereby starting exposure. When an exposure control mechanism detects prescribed exposure thereafter, the control circuits interrupts the supply of electricity to the coil 1. This results in that the pushing part 4b of the ring 4 receives strong resetting force in a counterclockwise direction from the projecting part 2a of the rotor 2. Therefore, when the supply of electricity to the coil 1 is interrupted, the ring 4 is quickly inverted of its moving direction, and closes shutter blades. The opening of the blade members is made sure in this way.

Title: Self-running vacuum cleaner
Inventor: FUJIWARA TOSHIAKI
IPC: G05D1/02
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To detect abnormal running immediately after starting in a short time, by operating a vacuum cleaner main body when a time for reaching the lowest current of a running motor is shorter than a time set by a timer part and stopping when the current does not reach the set value. SOLUTION: A running motor starts operation when a starting signal is outputted to the running motor and the current value gradually increases from 0 and reaches the maximum current value within 0.1 seconds and, after that, gradually reduces toward a stationary current value. Since the current exceeds a current value set by a minimum current setting part 26 within 0.1 seconds, a running logical signal is kept be continuously transmitted from a first logic part 29. However, since the current does not reach the minimum current value even after 0.1 seconds when the running motor 21 is not operating, a stop logical signal is transmitted from the first logic part 29 after 0.1 seconds. That is, when an abnormality occurred, the vacuum cleaner main body can be stopped after 0.1 seconds at the latest.
