Title: Casting method
Inventor: HATANO HIDEO
IPC: B22D7/00
Filed: 1986-01-29
Abstract: PURPOSE:To improve quality of casting products by connecting each lower end of cavity part with a runner through each ingate and also connecting each head part at the upper part of the cavity with a linked runner joined in a sprue. CONSTITUTION:The runner 4 in horizontal direction from a position at a little upper part of the sprue bottom 3 is formed, and also each ingate part 6 is arranged at the upper position of the runner 4 and is connected at each cavity 7 bottom. The head parts 8 are formed at the upper part of each cavity 7 and connected with the linked runner 9 arranged at horizontal direction, and its runner 9 is further jointed in the sprue 2. Molten metal poured into the sprue 2, is flowed to the runner 4, and at the same time, filled up in the cavity 7 from its lower position through the ingate parts 6. When the molten metal surface reaches to the head parts 8, new molten metal with high temp. floods in the head parts 8 through the runner 9 and mixes with the molten metal with low temp. to promote the heading effect. Therefore, the structure of the casting products is uniformized and the quality of it is improved.

Title: Ac-dc converter
Inventor: YOKOYAMA NOBUAKI
IPC: H02M7/219
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To reduce power loss caused by the voltage drop of a rectifier and improve the conversion efficiency of an AC-DC converter. SOLUTION: In an AC-DC converter according to this invention, most of energy stored in reactors 2 and 3 in the on-period of a pair of MOS-FETs 6 and 7 or a pair of MOS-FETs 5 and 8 in a switching circuit 4 is discharged through a bypass circuit 30 and a smoothing capacitor 10, when the pair of MOS-FETs 6 and 7 or the pair of MOS-FETs 5 and 8 are turned off while a thyristor 14 is in an on-state and an output current IDC is applied to a load.  With this constitution, the output currents IDC which are applied to respective parasitic diodes 5a-8a and a reverse-current preventive diode 9 in the switching circuit 4 when the energy stored in the reactors 2 and 3 is discharged are significantly reduced and hence power loss caused by the voltage drops of the respective diodes 5a-8a and 9 can be suppressed to a minimum, so that power loss caused by the voltage drops of the rectifiers such as diodes can be reduced and the conversion efficiency of an AC-DC converter can be improved.

Title: Shift control device for automatic transmission
Inventor: KURIYAMA MINORU
IPC: F16H61/08
Filed: 1992-01-31
Abstract: PURPOSE:To effectively prevent the occurrence of thrust torque without prolonging the shift period at the time of a shift when the up-shift of a main transmission and the down-shift of an auxiliary transmission are performed nearly simultaneously. CONSTITUTION:A main transmission 3 and an auxiliary transmission 4 are provided in series on an automatic transmission T. At the time of a shift when the up-shift of the main transmission 3 and the down-shift of the auxiliary transmission 4 are performed simultaneously, the completion of the up-shift of the main transmission 3 is delayed than the completion of the down-shift of the auxiliary transmission 4, the clutch pressure of the main transmission 3 is increased and the ignition timing is retarded after the completion of the down-shift of the auxiliary transmission 4, thus the occurrence of thrust torque is prevented without increasing the shift period.

Title: Dither picture encoder
Inventor: AKIYAMA HIROYUKI
IPC: H04N1/41
Filed: 1988-01-29
Abstract: PURPOSE:To easily specify address in a buffer memory and to easily edit data by allowing the coordinate of original data and the coordinate of a compressed code to coincide each other. CONSTITUTION:As encoding is executed by regarding a matrix size executing dither processing as a unit, the coordinate of the compressed code and the matrix coordinate of the original data coincide each other. For example, in a memory map showing the relation of the matrix coordinate of the original data and the coordinate of the compressed code, the original data shown by the matrix AA is made to be the matrix BB after being dither-processed and compressed-encoded and stored in the buffer memory as it is shown at the upper part of a figure by being expanded. Besides, the original data shown by the matrix A is also made to be the matrix B and stored in the buffer memory. Thus, before transmitting data, the edit such as one part of the data is deleted or expanded can be easily executed.

Title: Color image forming device
Inventor: HANEDA SATORU
IPC: G03G15/05
Filed: 1995-02-03
Abstract: PURPOSE: To prevent the effect of the potential of a former toner image from being exerted on the next toner image when the toner image is formed by superposing identical-polarity toner by executing a corona electrostatic charge action for smoothing the potential with respect to the toner image of an image forming body and forming the next toner image on it thereafter. CONSTITUTION: Before the toner image is formed by a second-color toner flying means 130M, the electrostatic charge action of the identical negative potential to a first color is executed again by the corona electric discharge of a scorotron electrostatic charger 112 on which a DC power source is impressed. Then, the toner image is formed on a recording paper P whose potential is smoothed by executing the electrostatic charge action again by the positive toner of the flying means 130M. The negative potential of the recording paper P on which the second-color toner image is formed in the same way as the case of the first color is lowered at the part to which the second color toner is attached.  Because of it, the potential is smoothed by executing the electrostatic charge action of the identical negative potential to the second color again by a scorotron electrostatic charger 113 before the toner image is formed by a third-color toner flying means 130C.

Title: Am stereo receiver
Inventor: TAKAYAMA KAZUO
IPC: H04S1/00
Filed: 1985-01-31
Abstract: PURPOSE:To expand the high frequency band of a signal falsely without deteriorating an SN ratio and to separate right and left sounds efficiently by arranging a stereo characteristic expanding device between an AM stereo decoder and a power amplifier. CONSTITUTION:Signals Rch, Lch outputted from the AM stereo decoder 12 are applied to a BPF20 and a mixer 26 in the stereo characteristic expanding device 14. The high frequency band of both the signals Rch, Lch is expanded up to about 7kHz. A BPF20 passes 3.5kHz-7kHz out of the whole band and the filtered signal is amplified by an amplifier 22. Since the I/O characteristic of the amplifier 22 is like an exponential function, the amplified waveform is distored and includes a higher harmonic. A BPF24 extracts 7kHz-14kHz which are the higher harmonic component and inputs the extracted component to the mixer 26. Since the mixer 26 applies the input component to the output of the decoder 12, the high frequency band of said output up to about 7kHz is expanded up to 14kHz. Since the amplifier 22 has the exponential characteristic, the level difference between the right and left levels is expanded and the false separation between the right and left sounds is improved.
