Title: Range hood
Inventor: ITO YASUHIDE
IPC: F24F7/06
Filed: 1987-06-30
Abstract: PURPOSE:To make it possible to easily clean oil dust which cannot be arrested by a filter and enters into the main body of the range hood by providing a panel blocking the inlet of a hollow part within the main body on the range hood and dividing the panel into two parts to make it attachable and detachable. CONSTITUTION:A panel 9 is provided on the front surface of a casing surrounding a fan 3 in an attachable and detachable manner, and an inlet 12 of a hollow part 11 formed between a fan casing 8 and the main body 1 of the range hood is blocked. Further, the panel 9 is divided into two parts which are lapped at a part shown by reference numeral 13 and fixed by a thumb nut 14. Oil smoke passing through a filter 3 causes oil dust to attach on the front surface of the panel 9. However, since the panel 9 is provided in an attachable and detachable manner, it can be easily cleaned and divided into two parts. Attachment and detachment of the panel 9 within the narrow range hood main body 1 can greatly improve the workability.

Filed: 1987-06-30
Abstract: PURPOSE: To obtain a liquid crystal display device which is free of flicker generation and has high reliability by driving the device while varying the amplitude of a voltage applied to a scanning signal line according to the level of a voltage applied to a display signal line. CONSTITUTION: Each pixel is composed of a thin film transistor 4, a liquid crystal cell 5, and a signal voltage holding capacitor 6; and the gate terminals 7 of laterally arrayed thin film transistors 4 are connected to the same address line YJ and the drain terminals 8 of longitudinally arrayed thin film transistors 4 are connected to the same signal line Xi . Then the device is driven while the amplitude of a voltage applied to a scanning signal line Y is varied according to the level of a voltage applied to a display signal line X. Therefore, the device can be driven so that effective gate potentials in the high-potential side field and low-potential side field of a display signal which is inverted in polarity are nearly equal. Consequently, the variation of the voltage applied to liquid crystal 5 becomes vertically symmetric about a counter electrode potential and the generation of a flicker can be prevented.

IPC: G09C1/00
Filed: 1988-06-30
Abstract: PURPOSE:To reduce the scale of the circuit by carrying out residue arithmetic without using any residue table and calculating a residue by simple addition processing. CONSTITUTION:While it is noticed that an RSA encipherment system is used, i.e. that a numeral to be raised to power is smaller than a divisor, the residues of partial products corresponding to the respective bits of a numeral as a multiplier are calculated by the simple addition through a residue computing element 3 and outputted. Further, a cumulative residue arithmetic part 4 adds the residues outputted by the residue computing element 3 in order to find the residue of the cumulative value. Namely, the desired residue arithmetic is performed without using any residue table and the residue calculation is carried out by the addition processing. The bit length handles in the circuit is only L bits (L: integer larger than 2) longer than the bit length of the divisor. Consequently, the circuit scale reducible.
