Title: Power supply
Inventor: IWABORI YUTAKA
IPC: H02M3/155
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To enhance safety by connecting the AC input terminal of a full-wave rectifier with an AC power supply through a filter circuit and connecting a first and second diodes in the flowing direction of charging current of a smoothing capacitors, thereby preventing an undue input power from being fed with respect to the output power, at the time of increasing the load circuit current. SOLUTION: When a switching element Q is turned on, energy is fed from a smoothing capacitor EC and an AC power supply P to a load circuit Z, through an inductor LM (mode 1). When the load voltage Vz reaches the voltage Vc of the smoothing capacitor EC, an operation for storing energy in the inductor LM, only from the AC power supply P, is started along with the operation in mode 1 (mode 2). When the switching element Q is turned off, the energy stored in the inductor LM is discharged to the smoothing capacitor EC and the load circuit Z (mode 3). When the load voltage Vz drops below the voltage Vc of the smoothing capacitor EC, energy is discharged from the inductor LM, only to the load circuit Z (mode 4).

Title: Ignition timing adjusting method internal combustion engine of vehicle
Inventor: ITOU YOSHIYASU
IPC: F02P5/153
Filed: 1981-09-28
Abstract: PURPOSE:To prevent a unnecessary output drop by delaying the ignition timing of a cylinder located part from a knock sensor only when the operating state of an internal combustion engine is placed in a region where generation of a  knocking vibration is predicted. CONSTITUTION:In an outer cylinder internal combustion engine, the ignition timing of a sparking plug 13 is controlled by mounting one knock sensor 50 on the outer peripheral wall part of a cylinder block 11 and by controlling an igniter 15 by an electric control circuit 100 according to an output from said knock sensor. In this case, ignition timing in a cylinder (separate cylinder) located relatively apart from the mounting position of the knock sensor 50 is controlled such that it is delayed by a prescribed angle only when the operating state of the internal combustion engine is placed in a region where generation of a knocking vibration is predicted. Hereby, unnecessary output drop and excessive fuel consumption conventionally caused by always delaying ignition timing by a prescribed angle in a separate cylinder can be prevented.

Abstract: PURPOSE: To equalize the distribution of the concn. of liquid poison in a calandria tank, by reducing the quantity of heavy water flowing into a heavy water passage of a surrounding portion of an earthquake-proof plate by mounting a projected wall to a lower portion of the surrounding portion of the earthquake-proof plate adjacent to said heavy water passage at equal distances from a reactor core.  
     CONSTITUTION: A projected wall 8 is mounted onto the same concentric circle as a calandria tank 2 toward a vertical just under portion from a boundary portion of a surrounding portion adjacent to a heavy water passage 9 of a surrounding portion of an earthquake-proof plate 3. The lenght of the projected wall 8 is approx. same as the width of the heavy water passage 9, and the projected wall 8 prevents the inflow of heavy water 5 flowing in from the holes 13 of a control rod guide tube 6 to the heavy water passage 9 and increases the rate of heavy water 5 passing through the heavy water passages 4 of the earthquake-proof plate 3. Thus, the inequality of the distribution of the conc. of liquid poison in the calandria tank 2 can be prevented even if changing the concn. of liquid poison in heavy water 5.

IPC: B65H9/16
Filed: 1994-07-07
Abstract: PURPOSE:To easily classify a bundle of discharged paper for every job and to obtain continuous paper discharging for each job by forbidding a push-and- shift action when a bundle of discharged paper in the preceding job is detected and performing the push-and-shift action either when a bundle of discharged paper in the preceding job is not detected or when it was once detected but it is no longer detected thereafter. CONSTITUTION:When one image forming job is completed, execution of a subsequent job is forbidden once in order to detect whether or not the discharged paper in the preceding job remains as it is pushed/shifted by a collating bar 33 by using a this-side-take-out sensor 36. In case where the discharged paper in the preceding job remains, a message requiring the discharged paper to be removed is given to a user via an operating part. When no discharged paper in the preceding job is detected, the push-and-shift action to the discharged paper in the present job is performed, and execution of subsequent image forming job is allowed, thereby completing the control over the present job. Thus, a break for every job by means of the push-and-shift action can be maintained, while a bundle of discharged paper for every job can be classified easily.

Title: Optical memory cell

IPC: G11B7/24091
Filed: 1990-06-13
Abstract: PURPOSE:To obtain an optical memory cell whose quality is satisfactory by providing a track guiding groove which has a narrow width in a section adjacent to a preformat area, as the density of a pre-pit is increased. CONSTITUTION:A track guiding groove 2 has a width W1 in a first section 2a adjacent to a pre-format 4, which is formed in order to be narrower than a width 2 of a second section 2b adjacent to an information recording area 5, according to the density of a pre-pit 3. That is, the width W1 is successively formed in order to be narrower than the width W2, according to the density of the pre-pit 3. Therefore, a value such as a VFO signal at the time of regeneration can be enlarged, and also the value of a track cross signal can be reduced in areas except for those in which the VFO signal or the like is recorded. Because of this, there is plenty of room for a standard value, and it is not necessary to precisely formed the width of the track guiding groove. Thus, the optical memory call whose quality is stable can be formed, and the yield is improved.
