Title: Chiller for casting
Inventor: IMURA TAKESHI
IPC: B22D15/00
Filed: 1982-07-12
Abstract: PURPOSE:To suppress the cooling of molten metal in the initial period of charging and to improve the run of molten metal by forming fine ruggedness on the surface of a chiller body in contact with molten metal. CONSTITUTION:A sprue 2 and a product cavity 3 having a vane part 3a, and a hub part 3b are provided to a gypsum casting mold 1 for a compressor wheel, and a chiller body 4 is assembled on the bottom surface in the part 3b of the cavity 3. Fine ruggedness 5 is formed on the surface of the body 4 where the body contacts with molten metal. The molten metal contacts only with the projecting parts of the ruggedness 5 by the surface tension thereof in the initial period of charging from the sprue 2 and the recesses remain as spaces, therefore the transmission of heat to the body 4 is kept low, whereby the deterioration in the fluidity of the molten metal is prevented as far as possible and the run to the part 3a is improved. When the molten metal is filled in the cavity, the contact area between the recesses and the molten metal is increased by the pressure of the molten metal and the cooling effect by the transmission of heat to the body 4 is thoroughly provided.

IPC: H02M7/217
Filed: 1990-05-11
Abstract: PURPOSE:To reduce cost and improve efficiency by providing two primary windings, whose polarities are reverse against one secondary winding of a transformer in a power unit, which contains an inverter, and controlling the current of said primary winding with a control switch, and approximating the input current waveform to a sine wave. CONSTITUTION:A frequency conversion circuit 11 comprises transistors(TRs) Q1-Q4, primary windings 12 and 13, secondary winding 14, etc. The polarities of the primary windings 12 and 13 are made reverse to each other. Trs Q1-Q4 are turned on or turned off in the cycle half the saw wave V2 of 50kHz. While Trs Q1-Q4 are on at the same time, the currents of the primary windings 12 and 13 are proportionate to current voltage. At this time, voltage is not induced in the secondary winding 14. While Trs Q1-Q2 are on and Trs Q3 and Q4 are off, a current flows to the primary winding 12, and voltage is induced in the secondary winding 14. By such control, voltage of 25kHz is induced in the secondary winding 14. During the off period of Trs Q1-Q4, it is controlled referring to input voltage, output voltage, input current i2, etc.

Title: Data transmission equipment
Inventor: MURAKAMI YUICHI
IPC: H04L13/00
Filed: 1985-06-03
Abstract: PURPOSE:To simplify the destination whether a system is in the standby state or not by starting data transmission after a not modulated carrier is outputted from a sender side so as to allow the reception side to discriminate easily the presence of the reception of carrier. CONSTITUTION:When a signal line SG1 is at a high level H, a power unit 20 outputs a voltage of 5V to a power line Vc2 and outputs a voltage of 5V to a power line VCC, and when a level of the signal line SG1 goes to a low level L, the voltage of the power line Vc2 is switched to nearly 2.5V and the voltage of the power line VCC goes to 0V. When the voltage is 2.5V, the sensitivity is lowered, then no hindrance is given to the operation to discriminate the radio wave reception. When the radio wave is outputted at the sender side, the non-modulation period of nearly 200msec is provided at first. Thus, even when the radio wave is received right now, the signal line SGI goes to a high level H surely.

Abstract: PURPOSE:To restart a rotor easily by distributing the magnetic field of a rotor magnet so that the electrical center of magnetic poles at a time when a coil for a stator is excited is displaced from the mechanical center of each magnetic pole for the rotor magnet. CONSTITUTION:A coil 5 corresponding to two phases is wound, forming slots 3a-3d and tees 4a-4d, thus shaping a stator 2 with four poles. The inside of a rotor magnet 1 mounted to the outer circumference of the stator 2 is mag netized alternately at N poles and S poles at every 90 deg.. The inside of the rotor magnet 1 is magnetized in such a manner that the intensity of a magnetic field in the radial direction of each magnetic pole is altered along the circumfer ential direction while positions where the intensity of magnetic fields in the radial direction of respective magnetic pole is maximized are displaced only by predetermined dimensions in the circumferential direction from the mechani cal center of magnetic poles. That is, lines X tying the positions A of the maxi mum magnetic fields of the opposite magnetic poles are displaced only by angles thetain the circumferential direction from the mechanical center lines Y of the magnetic poles. Accordingly, even when the rotor magnet 1 is stopped anywhere, self-start is enabled, thus resulting in smooth revolution.
