Title: Control system of inverter
Inventor: ISHIKAWA SHINICHI
IPC: H02M7/48
Filed: 1980-07-26
Abstract: PURPOSE:To prevent formation of short-circuit by the transistor by a method wherein the suspending period of an interrupted DC output voltage is made as shorter than the storage time of the transistor. CONSTITUTION:A prohibition pulse generating circuit 46 is annexed to a chopper circuit 2 to interrupt a DC voltage and to regulate an output voltage controlling the duty ratio of interrupted pulses, and the suspending period of chopper output voltage is limited as to become shorter than the storage time of transistors 13-16 according to control of voltage. Accordingly because the suspending period does not become shorter than the prescribed time being set as a little longer than the storage time, generation of chopper output voltage during the transistors 13, 14 are together in ON-state is restricted, short-circuit to be generated by the transistors 13, 14 is not formed, and short-circuit to be generated by the transistors 15, 16 is not formed samely.

Title: Single converter
Inventor: OOTSU SHINICHI
IPC: H02M3/335
Filed: 1981-06-30
Abstract: PURPOSE:To ensure the effective use of the excited energy, by connecting the third winding containing a parallel stabilized circuit with the additive polarity opposite to the electromagnetic connection style between the primary and secondary windings. CONSTITUTION:When the closure of a switching circuit 11 is released, the voltage induced to the third winding 21 by the excited current flowing to the primary winding 13 is supplied to a parallel stabilized circuit 23 via a single wave rectifying circuit 22 and then to the 2nd load 25. The circuit 23 transmits the excited energy to the load 25 so that the sum of the electric power consumed at a transistor 23c and the electric power consumed at the load 25 is equal to the excited energy transmitted via the winding 21 although the power consumption of the load 25 has the fluctuation. As a result, the excited energy is thoroughly consumed althrough the power consumption of the load is reduced down to zero.

Title: Sheet separating and feeding method and its apparatus
Inventor: SATOU MITSUHIRO
IPC: B65H3/06
Filed: 1978-08-25
Abstract: PURPOSE: To permit certain separation of sheet by forming an air layer between the sheet to be sent-out and the next sheet to be sent-out, previously to the separation and feeding of sheet.  
     CONSTITUTION: As the revolution of a feeding roller 7 and a first auxiliary feeding roller 18 does not begin yet when the lowest sheet in a sheet aggregate begins to be fed-out by a second auxiliary feeding roller 19, the sheet begins to be bent downward in the direction of a hollow part 3 at the intermediate part. After a fixed time, the feeding roller 7 and the first auxiliary feeding roller 18 start revolution, and as the peripheral speeds of the feeding roller 7 and the first auxiliary feeding roller 18 are lower than that of second auxiliary feeding roller 19 having started revolution already, the sheet passes through the slit between a sheet stop roller 15 and the upper surface of a sheet loading rack, generating an air layer at the part corresponding to the hollow part 3, and the sheet is sent out rightward, and thus the separation of sheet is made certain.

Title: Image recorder and electronic camera
Inventor: SUZUKI TAKESHI
IPC: H04N19/30
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To attain recording matching characteristics of image data that are hierarchically coded. SOLUTION: In the case of recording image data that are hierarchically coded, a 1st CPU (CPU#1) 25 writes image information with all frequency bands from a low resolution to a high resolution to a recording medium 24 regardless of a recording image quality mode designated by a user in a 'high definition mode' in the case of recording by taking a feature of a data structure, where a compression rate of the image data even after the recording can easily be changed, into account.  When an unrecorded capacity of the recording medium 24 reaches a prescribed capacity or below, the 1st CPU (CPUξ1) 25 eliminates parts of excess high resolution image information from the image data having been recorded in the recording quality mode whose quality is higher than that of the mode designated by the user and changes the recording quality mode into a 'normal mode' or a 'simplified mode' designated by the user.

Title: Method and mold for molding handle of toothbrush
Inventor: TOBE HIDETAKE
IPC: B29C45/26
Filed: 1989-04-24
Abstract: PURPOSE:To obviate the need of the after-processing operation of a gate cut-off part by a method wherein resin is filled through runner from a gate into a cavity and, by separating a second movable retainer plate from a first movable retainer plate, the resin at the gate is cut-off. CONSTITUTION:Resin is filled through runner 4 and a gate 9 in the cavity parts 6 and 5 of a mold in order to mold a handle 21. After the finish of molding, a mold opening is started by parting a first and a second retainer plates 2 and 3 from a retainer plate 1 and, after that, the second movable retainer plate 3 is parted from the first movable retainer plate 2. At the parting of the retainer plate 3 from the retainer plate 2, the hanging eye 22 of the handle 21 is drawn out of a first projecting part 7 and retreated together with a second projecting part 8, since the hanging eye is convergently slanted inward by means of the first projected part 7 and the annular projection 10 of the second projected part 8 invades into the inner peripheral surface of the hanging eye. In this case, since the resin in the gate 9 lies within the first movable retainer plate including the first projecting part 7, is cut off at the connecting part from the resin in the hanging eye part 22, which retreats together with the second movable retainer plate 3. Thus, the finishing process of the gate cut-off part becomes unnecessary.

Title: Input protection system of call and answer detecting circuit
Inventor: MATSUYAMA MITSUO
IPC: H02H9/04
Filed: 1983-06-13
Abstract: PURPOSE:To attain an electronic constitution for the call and answer detection part in a switchboard by providing a circuit constitution which varies to low impedance when a voltage level exceeds the voltage level set only on the basis of the ground potential. CONSTITUTION:When call and answer detection operation is performed, a call signal current flowing through a resistance is converted by a current converting circuit 12 into a low level current proportional to an input, and the low-level current is converted by resistances 20-23 of an overvoltage limiting circuit 23 into a voltage, which is applied to a DC detecting circuit 18. The voltage which is applied to the DC detecting circuit 18 and proportional to the call signal current is filtered by a low-pass filter 16, and a comparator 17 outputs a call answer signal when the output of the low-pass filter 16 contains a DC component and its voltage level is higher than the reference voltage set by a DC voltage source 9. The overvoltage limiting circuit 23 has low impedance when the output current of the current converting circuit 12 increases, so that an overvoltage input to the DC detecting circuit 18 is suppressed by setting the resistance to a proper value.
