Title: Injection control method of die cast machine
Inventor: TAKAMURA MASAYUKI
IPC: B29C45/53
Filed: 1995-06-01
Abstract: PURPOSE: To provide a cast free from gas inclusion by controlling the position and the speed of a plunger based on the diameter of the injection plunger, the injection stroke, and the injection speed which are preset so that the elevating speed of the molten metal level is approximately kept constant. CONSTITUTION: Water is fed at the constant flow rate to a container 20 having overflow where a cast is stored in the same posture as that of the cavity C, the very small displacement of the water level for a unit time is continuously measured, and the very small amount of molten metal to be fed is continuously obtained and totalized from the data on the horizontal sectional area at the position of the very small displacement. The total amount of the molten metal with a biscuit and a runner added thereto is obtained, the injection stroke and the injection speed are set from the diameter of an injection plunger so that the elevating speed of the level of the molten metal to be filled in the cavity C is approximately constant, and the casting is achieved by controlling the position and speed of the plunger based on the conditions of injection.  This method can finely cope with any complicated shape, and the casting free from gas inclusion can be achieved.

Title: Inverter
Inventor: ASAEDA TAKEAKI
IPC: H02M7/5387
Filed: 1987-06-25
Abstract: PURPOSE:To contrive to improve the feedback effect of snubber energy by changing the magnetic flux of a rectifier in both positive and negative directions by a thyristor circuit. CONSTITUTION:In a lagging current mode, if the ON-signal of a thyristor 8a is released at the time t3 and given to a thyristor 8b, said thyristor 8a is turned OFF by a capacitor 8c. The electric current ICT of a current transformer 6A charges said capacitor 8c with electricity in reverse direction and a diode 8e starts conduction. When the capacitor 8c has completed charging, said current ICT of the current transformer 6A flows through the thyristor 8b, the diode 8e, and primary windings 6a-6e of said current transformer 6A so that the polarity of the primary side voltage of the current transformer 6A is reversed too. Thus, the snubber energy at the time of commutation of an inverter can be fed back to the DC power side via the current transformer 6A, because the commutation timing of the thyristors 8a, 8b is set at a lag time Tds which is set to be longer than the dead time Td1 of commutation of said inverter.

Title: Multi-layer laminated type photo-electric converting device
Inventor: TOMONARI SHIGEAKI
IPC: H01L31/04
Filed: 1988-06-27
Abstract: PURPOSE:To obtain a multi-layer laminated type photoelectric converting device with a greater flexibility for the film thickness without changing materials forming each photoelectric converting layer by changing absorption coefficient of each photoelectric converting layer. CONSTITUTION:The film thickness of each photoelectric conversion layer is maintained to be 6600Angstrom  and the absorption coefficient of each photoelectric conversion layer is changed by varying the formation temperature of the film, where a photo absorption rate of each layer is expressed by an equation and alpha1, alpha2, alpha3 and may be determined so that these values are the same. W indicates 6600Angstrom , alpha1, alpha2 and alpha3 do absorption coefficients of the first, second and third cells, and W1, W2 and W3 do the film thickness. When alpha1, alpha2 and alpha3 are determined, the following is obtained, namely alpha1=5X10<3>(cm<-1>), alpha2=1.24X10<4>(cm<-1>) and alpha3=2.77X10<4>(cm<-1>). Formation temperature may be changed to achieve these absorption coefficients. Also, since the absorption coefficient becomes larger as the formation temperature becomes higher, the lowest layer, namely the layer formed initially becomes the hottest in terms of formation temperature. Thus, it does not produce any problem in terms of process to be realized.

Title: Interruption signal generating system
Inventor: OKUHARA TORAYUKI
IPC: G06F11/10
Filed: 1981-10-06
Abstract: PURPOSE:To enable an interruption signal to be outputted at the access time of a prescribed address by providing a CPU with a parity inversion circuit and mismatching the parity code of a data in an address corresponding to a break point. CONSTITUTION:In respect of data to be stored in a storage device 1, a parity is added to the contents of a data register 5 in a parity generating circuit 4. Ordinally a break point setting processing part 7 outputs ''1'' to a parity inversion circuit 8 to add a normal parity. In case of break point setting, the processing part 7 accesses the device 1 at an address where an interruption signal is to be generated and reads out data from the device 1. When the processing part 7 outputs ''0'' to the cirlcuit 8 and the contents of the register 5 is written in the device 1, a value having an inverted parity code is stored in the device 1. If a CPU2 accesses to said address in the device 1, a parity error checking circuit 3 detects an error and outputs an interruption signal to an interruption processing part 6. Consequently the interruption signal is outputted at the break point.
