Inventor: KOBAYASHI KAZUNORI
IPC: B22C13/08
Filed: 1981-03-03
Abstract: PURPOSE:To obtain a frozen shell mold of the desired thickness and strength quickly by cooling a metal pattern in which the mulled sand for moisture contg. molds is packed, beforehand down to the freezing point or below. CONSTITUTION:A metal pattern plate 1 is placed on a cooler 2 which is held beforehand to the freezing point or below with the liquid nitrogen, the liquid carbon dioxide or the refrigerant liquid, and the mold ejection pins 3 are provided to a pattern plate base 1'. When the mulled sand 4 for the molds contg. 2-5% moisture is dropped on the plate 1 and is packed in the mold, a frozen layer 5 is formed along the surface of the plate 1 because the plate is cooled beforehand to the freezing point or below. The thickness of the layer 5 is a function of time, and when it increases to the prescribed thickness, the unfrozen excess sand 4 is removed and further the sand is allowed to freeze to the prescribed hardness, after which the pins 3 are operated to strip the layer 5, whereby the desired shell mold is constituted.

Title: Bicmos inverter integrated circuit
Inventor: YANA KIYOUSEKI
IPC: H03K19/08
Filed: 1993-02-19
Abstract: PURPOSE: To reduce the number of constituent basic elements, to accelerate response speed and to miniaturize a chip by providing a resistance between the output side of an inverter circuit and the output terminal of a bipolar transis tor, stabilizing the bias voltage of a pull up transistor and speeding up a step up/down operation. CONSTITUTION: When a low level signal is inputted to an input terminal VIN, the pull up bipolar transistor Q1 is turned on in accordance with the turning-on of a PMOS transistor P1 and output potential rises to VDD by the P1 and a resistance R1 while parasitic capacitance C1 is speedily charged. When VIN is moved to a high level, the base charge of Q1 is suddenly discharged through an NMOS transistor N1 and a resistance R2 in accordance with the N1. The charge of the output terminal by C1 is biased to the base of the Q2 through the N1 and it speedily drops. Thus, response speed is improved, logic level potential is obtained, the number of the basic elements to be constituted is reduced and the chip is miniaturized.

Title: Magnetic bubble memory device
Inventor: FUJII TATSUHISA
IPC: G11C19/08
Filed: 1985-02-20
Abstract: PURPOSE:To prevent the data output competition of plural BMCs even if a CPU runs away, by masking a data read signal of a BMC of other side by a BMC selection signal of one side or a data transmission answer signal. CONSTITUTION:When either a selection signal -CS1 or a data transmission answer signal -TXAK1 in a magnetic bubble memory control circuit BMC1 of one side is selected by a NOR gate, it becomes invalid even if a data read signal -RD of a BMC of one side is input into an OR gate. Similarly, when a selection signal -CS1 or a signal -TXAK2 of the BMC2 is selected by a NOR gate 6, it becomes invalid even if a read signal -RD of the BMC1 is input into an OR gate 8. In such a way, the BMC1 and the BMC2 are simultaneously selected, the respective data read signal is invalid, and the data output is of high impedance. As this result, the output competition of the BMC1 and the BMC2 disappears.

Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a multi-stage display type electronic circuit apparatus with a function of displaying the shortage of the battery capacity, which realizes higher visual recognizability along with a drive by limited power consumption. SOLUTION: State of oscillation (for example, presence of oscillation or the altering of oscillation frequency) of an oscillation circuit 33 is generated based on changes in a terminal voltage V of a battery 1 and an electric field driven type display cell 5 is driven by an AC drive voltage Vac with the frequency corresponding to the state of oscillation. To be more specific, when the capacity of the battery 1 is not insufficient, a specified voltage is applied to the cell 5 to accomplish a display in a specified color. Immediately before the terminal voltage V of the battery 1 shows a specified shortage of the battery 1, a display of oscillation is performed to give a warning with a higher visual recognizability.  Moreover, with the capacity insufficient, the voltage applied to the cell 5 is lowered or cut and a color display is made different in color from that with the full sufficiency of the charging. This can reduce the burden on circuits, avoid the shortage of the capacity and improve visual recognizability of both warning signals immediately before the occurrence of the shortage of the capacity.
