Title: Color video signal recorder
Inventor: ISHIODORI MAKOTO
IPC: G11B20/02
Filed: 1978-11-09
Abstract: PURPOSE: To reduce beat disturbance in reproduction of color video signals on a SECAM system.  
     CONSTITUTION: Color video signals from terminal 1 are inputted to LPF2 and BPF5 and luminance signals separated from video signals by LPF2 are FM-modulated 3 and then applied to adder 9 after unneeded components are removed 2. Video signals separated by BPF5, on the other hand, are converted into a low frequency by frequency converter 6 by using the output of OSC8 and then applied as a low- frequency conversion color signal to adder 9 through LPF7, and the addition output is supplied to magnetic head 11 by way of amplifier 10. As converter 6, a balanced modulator, for example, is used and when a low-frequency converted chrominance subcarrier frequency is denoted (f c ) and a horizontal frequency (fH), (f c ) is selected as shown by formula (4) to make beat disturbance between (f c ) and 2(f c ) inconspicuous, thereby obtaining reproduced screens of high quality.

Title: Hydraulic drive for cooling fan
Inventor: HONDA NOBUHISA
IPC: F01P7/04
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To continuously drive a cooling fan at a constant rotating speed by controlling the opening area of a restriction mechanism interposed in the connection circuit for a variable displacement hydraulic pump and a cooling fan drive hydraulic motor through variation in the displacement of the hydraulic pump based on the differential pressure between its self-discharging pressure and the load pressure on the hydraulic motor. SOLUTION: A variable restriction mechanism 3 capable of varying its opening area is provided in the connection circuit for a variable displacement hydraulic pump 2 driven by a vehicle-mounted engine 1 and a fixed displacement hydraulic motor 4 for driving a cooling fan 6. When the flow rate in the restriction mechanism 3 gets larger than a predetermined flow rate as well as the differential pressure, P1 -P2 , between the self-discharging pressure P1 and the load pressure P2 gets larger than a predetermined pressure, a control valve 14 is switched over to its second position to reduce the displacement of the hydraulic pump 2 by a variable displacement piston 11 and thus to allow only the predetermined flow rate into the restriction mechanism 3.  When the flow rate in the restriction mechanism 3 becomes, however, smaller than the predetermined flow rate as well as the differential pressure, P1 -P2 , becomes smaller than the predetermine pressure, the control valve 14 is switched over to its first position to increase the displacement of the hydraulic pump 2.

Title: Image forming apparatus
Inventor: TANIOKA HIROSHI
IPC: G03G21/00
Filed: 1982-08-11
Abstract: PURPOSE:To easily and rapidly carry out image forming operation in an apparatus having multifunctions, by enabling copying in a mode having high use frequency through only one key operation. CONSTITUTION:A managing CPU202 detects the input of a copy key or the like from a key matrix circuit 204, and sands a copy instruction to a sequential CPU201. The CPU201 receiving this instruction starts image formation sequentially. A setting circuit 205 is allowed to set a desired copy mode by a user. When continuous copying is being operated with a user key, even if one of a switch array is changed over to change the mode, the CPU202 does not sense the changeover of the switch, so the initial mode copying is completed. As far as the user key is not turned on again, copying in that mode is not executed, thus preventing careless mode change during copying.

IPC: H02M7/21
Filed: 1978-11-10
Abstract: PURPOSE: To increase efficiency by connecting a field effect transistor to the secondary winding of a triasformer for DC-DC converter and the like, controlling it by the tertiary winding of the transformer, and performing rectifying operation in order to minimize losses.  
     CONSTITUTION: A DC-DC converter turns on and off a switching transistor 3, takes out an AC voltage through a transformer 2, rectifies it, and supplies a DC voltage to a load 7. A field effect transistor 5 is connected to the secondary winding of the transformer 2. The signal synchronized with the secondary winding is applied across the gate and source of the transistor from the tertiary winding of the transformer 2, thereby rectifying operation is performed.

Abstract: PURPOSE:To transfer a bucket with a simple control part by providing a means detecting the presence or absence of a change in a signal on a line only for a previously decided time and a means which continuously transmits a prescribed bit pattern which has been previously decided. CONSTITUTION:A first station 21 supervises the state of the line 1 only for the previously decided time by a line supervising unit 3, judges that the line 1 is in an inactive state if there is not any change in the signal on the line during that time, sets data to be transmitted to a prescribed constitution and starts transmitting the bucket. If the supervising unit 3 detects the change on the line 1 within the prescribed time, it judges that transmission has succeeded, transmits a transmission normal termination signal 12 to a transmission control part 4, which informs a host system of transmission normal termination. If a reception N station 22 recognizes that there is not any error in the received bucket in a reception control part 5, it outputs a reception termination signal 14 to a bit pattern transmitter 6. It transmits the prescribed bit pattern on the line 1 for the previously decided time.

Abstract: PURPOSE:To accurately detect a laser beam scanning position without any influence by the variation in the intensity of laser beam by starting the recording of an image at a time point of a certain time is over from the time of detecting a pulse signal. CONSTITUTION:A light detector 33 detects an image recording starting time. A waveform trimmer 34 trims a detection signal from this detector 33 by comparing it with a prescribed reference value. A pulse whose width waveform is thus trimmed is measured by a pulse width measuring device 38. A delay time setting circuit 39 sets a dealy time for the pulse signal in accordance with a measured value. A first delay circuit 35 delays the waveform trimmed by the timmer 34 for a certain time. Such a circuit 35 does not output a pulse signal to a second delay circuit 36 untill the measuring of pulse width by the device 38 ends. The second dealy circuit 36 delays the pulse signal for a time set by the circuit 39. Because of an input pulse signal, a counter 37 executes its counting, and output a print start signal when a set counting value is obtained.

IPC: F01P11/00
Filed: 1979-10-30
Abstract: PURPOSE: To rapidly inject cooling water into a water jacket, by connecting the water jacket to a negative pressure source to provide negative pressure in the water jacket.  
     CONSTITUTION: The interior of a second tank 81 is kept at negative pressure not higher than about 250mmHg, by the operation of a vacuum pump 82. When a valve 130 is opened in that state, air in the water jacket 16 of an engine 2 is sucked out into the second tank 81 by the negative pressure therein. The operation of the vacuum pump 82 is continued so that the interior of the water jacket 16 is set at negative pressure not higher than about 250mmHg. When it is detected that the negative pressure has become not higher than said value, valves 85, 130 are automatically closed and the first tank 79 and a hole 77 are connected to each other through another valve 84. As a result, cooling water in the first tank 79 flows into the water jacket 16 of the engine 2 through the first tube 87, the hole 77, a port 24 and a hose 22.
