Abstract: PURPOSE:To obtain an easy-to-see gradational display at all times irrelevantly to temperature by varying the ratio of the time of the application of a selective voltage to signal electrodes and the time of the application of a nonselect voltage at respectively gradation levels with the temperature. CONSTITUTION:The radio of the time of the application of the selective voltage to the signal electrodes and the time of the application of the nonselective voltage at the respective gradation levels is varied with the temperature. For example, the output of a temperature sensor 1 is inputted to a ROM 3 through and A/D converter 2 and a clock signal is inputted to and converted by a counter 5 to a waveform (a) obtained by dividing one selection cycle by 64, and then sent to the ROM 3. The ROM 3 generates a signal waveform (b) which determines gradation pulse width with the signal sent from the counter 5 and the signal sent form the A/D converter 2. The waveform outputted by the ROM 3 is sent to a driver for gradations through a flip-flop circuit 4 and this driver outputs voltage waveforms (c) - (h) to be applied to the signal electrodes according to the gradation levels of picture elements. Consequently, the easy-to-see gradational display can be obtained irrelevantly to the temperature.

Title: Memory switching circuit
Inventor: SUZAKI SATORU
IPC: G06F9/06
Filed: 1981-09-14
Abstract: PURPOSE:To utilize address space effectively, by allowing writing to and reading from an RAM located in the same address space with a starting ROM, after the execution of a program of the starting ROM. CONSTITUTION:A chip selection terminal CS' is provided to an ROM1 and an RAM2. The memory operates only when the terminal CS' has a level L. The RAM2 is provided with a signal terminal WT' which goes down to the level L during writing operation. An inverter 5 goes down to the level L after being powered up through an initial resetting circuit 4. An FF6 is reset up to said point of time and its output Q' has a level H, sending a signal to the ROM1. At this time, the output Q has the level L, so no signal is sent to the terminal CS' of the RAM2. Therefore, the ROM1 for starting is selected right after the power source is turned on. Once a write signal WT' is outputted to the RAM2, a set input is supplied to the FF6 and while the output Q goes up to H, the output Q' goes down to L. Consequently, the signal CS' is sent to only the RAM2.

Title: Writing utensils holder
Inventor: SAKURAMACHI HIROKI
IPC: B43K3/00
Filed: 1988-06-13
Abstract: PURPOSE:To obtain a writing utensil holder having an anti-slip effect and always feeling pleasant by using a thermoplastic plastic material including porous silica powder having a specific pore diameter. CONSTITUTION:The whole or surface of a writing utensil holder is formed by including 5-30% porous silica powder having a pore diameter of 10-250Angstrom  in a thermoplastic plastic material, but the latter is formed by double-extrusion molding. When the writing utensil holder is left to stand in a high-humid atmo sphere, the pores of the porous silica successively adsorb water content in the order of increasing pore diameter from the smallest one first with increasing humidity. However, with decreasing humidity the pores exhibit a respiratory action of again desorbing the water. Namely, when a hand is in a sweat, the pores immediately adsorb the moisture of the sweat; however, the adsorbed moisture is released to atmosphere when the writing utensil is usused. Thus, the writing utensil can be continuously used.
