Title: Automobile headlight
Inventor: IIZUKA SHUNICHI
IPC: F21S8/10
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To prevent users from feeling discomfort by making it possible to rapidly defog, through the turning on of a light source, a non-emitting part fogged by dew condensation. SOLUTION: In this automobile headlight 1, an antifog reflecting surface 9 which reflects the light beams of a light source 5 toward portions near a non-emitting part 2b on at least a part of a lens 2 is integrated with the inner surface of a hood 7. Therefore, the non-emitting part 2b, which was the cause of impairing the feeling of the quality of the lamp as it takes time to defog and makes users feel discomfort since the light beams do not directly reach the non-emitting part 2b even when the light source 5 is turned on, is rapidly defogged by heat rays involved in the light beams, by allowing the light beams to reach the non-emitting part 2b by use of the antifog reflecting surface 9 provided integrally with the inner surface of the hood 7.

Title: Semiconductor integrated circuit
Inventor: SATOU HIROAKI
IPC: G11C17/00
Filed: 1983-05-25
Abstract: PURPOSE:To allow a user to write or read additive information without increasing the number of terminals nor reducing the storage capacity of a main memory by adding the 2nd memory cell array stored with the additive information in addition to a memory cell array for practical use and using a gate which operates only at levels except that of TTL to obtain a multifunctional terminal. CONSTITUTION:The 2nd memory cell array 5 is stored with the additive information such as an identifying code, etc., and the 2nd X decoder is a decoder for the identifying code. A Y decoder 3 and an output circuit 4 are invariably activated when the 1st memory cell array 1 is activated and when the 2nd memory cell array 5 is activated. When a level other than the TTL level is inputted to a terminal Ai, the 2nd memory cell array is activated and the 2nd memory cell array is inactivated, and when the TT1 level is inputted, they are activated and inactivated reversely.

Title: Liquid crystal cell
Inventor: TERADA TOSHIYUKI
IPC: G02F1/1333
Filed: 1990-04-09
Abstract: PURPOSE:To reduce the heater capacity, to improve the heat efficiency and to eliminate an adverse influence upon a polarizing plate by providing a heater layer made of a transparent electrode material on the inside of one transparent substrate. CONSTITUTION:A heater layer 6 made of a transparent electrode material is provided on the inside face of one transparent substrate 2b among two transparent substrates (glass plates) 2a and 2b, and an insulating film 8 having a multilayered structure is interposed between the heater layer 6 and a liquid crystal driving transparent electrode 3b. Since the heater layer conventionally provided on the outside of the polarizing plate is provided on the inside, the heater layer 6 and a liquid crystal layer 1 are approached with each other, and the heater capacity is reduced, and the heat efficiency is improved to shorten the temperature rising time of liquid crystal, and this device is effectively used for liquid crystal display on a vehicle at a low temperature. Since a polarizing plate 4b is on the side opposite to the heater, a high temperature is not transmitted to the polarizing plate 4b.

Title: Graphic painting-out method
Inventor: MIKAGI MASATO
IPC: G09G5/36
Filed: 1989-04-12
Abstract: PURPOSE:To paint out a graphic at high speed by erasing apexes corresponding to peak and trough parts from a two-dimensional picture memory and afterwards, executing processing to thin out a line. CONSTITUTION:At first, it is investigated whether the respective apexes of closed and linear graphics A and B are corresponding to the peak and trough parts or not. The peak and trough parts are a point (peak) protruded in upper direction (direction perpendicular to a scanning line) in comparison with the back and forth apexes and a point (trough) protruded in lower direction among the apexes constituting the closed and linear graphics. The apexes decided to be corresponding to the peak and trough parts are erased from a two-dimen sional picture memory 1. Next, line thinning-out processing is applied to remain one significant picture element and to reload the other significant picture ele ment to non-significant picture element when more than two significant picture elements continuously exist on the same scanning line. Thus, the plural closed and linear graphics to be respectively independent can be simultaneously painted out and the processing time is shortened.

Title: Pll circuit
Inventor: YANAGAWA HIROICHI
IPC: H03L7/183
Filed: 1990-04-08
Abstract: PURPOSE:To lock the output frequency of an oscillator to a desired frequency without passing an image frequency by setting a PLL loop to a nonlock state while a frequency division data is inputted to set a control signal to an oscillator to an upper limit or a lower limit level, thereby setting a frequency division ratio. CONSTITUTION:When '110' is inputted to a frequency control section 20 as a frequency data Fd, for example, a local oscillation changeover switch 13 is thrown to the position of a 100MHz local oscillation signal, and a serial data '10' is outputted to a shift register 15 synchronously with a clock pulse as a frequency division ratio data N. While the clock pulse is outputted continuously from a time t1, an output of a timer circuit 17 is brought into an H level and a switch circuit 18 is used to interrupt a loop of a PLL circuit 10. Since a phase comparator 3 during the interruption decides it that the frequency of the frequency division output signal is lower than a frequency Fr of a reference signal, a control voltage V keeps rising up to its upper limit. However, when the output of the circuit 17 restores to an L level at a time t2, the loop is in the connecting state and the frequency is decreased toward 110MHz.

Title: Manufacture of gas discharge panel
Inventor: OOTSUKA AKIRA
IPC: H01J11/10
Filed: 1982-05-31
Abstract: PURPOSE:To prevent discharge concentration of a gas discharge panel by applying AC voltage between display electrodes after forming an electrode pattern and forming a thicker insulating layer than that of other portions in the portions where glow discharge is concentrated, by glow discharge deposition method. CONSTITUTION:After electrodes are formed on a glass base 1, AC voltage is applied between display electrodes 4 and 5, and thicker insulating layers than those of other portions are formed in inner edges, where discharge is concentrated, of the display electrodes 4 and 5 by glow discharge deposition method. An insulating layer 6 is formed so that glow discharge strength distribution is uniformed. When AC voltage is applied between the discharge electrodes 4 and 5 having the insulating layer 6 of a gas discharge panel, discharge concentration in the vicinity of the inner edges of the electrodes is reduced, and discharge is uniformed on the surface of the electrodes. As a result, the life of the panel is increased, and display without a glass cover 3 becomes uniform to increase display quality and operation margin is increased.

Abstract: PURPOSE:To improve productivity and to lower fuel ratio by using highly accurate coke temp. at raceway part in a blast furnace as information of furnace heat, combining it with the theoretical combustion temp. and rapidly executing operation under blasting condition for adjusting the furnace heat. CONSTITUTION:The coke temp. Tc at the raceway part in the blast furnace is detected from the tuyere part and also the ratio Tc/Tf of Tc to the theoretical combustion temp. Tf is calculated, and Tf and/or fine powdered coal quantity blown from the tuyere part are adjusted beforehand so that this ratio is in the set range. Tc can be detected under good accuracy by arranging a radiation thermometer at peeping hole part in the tuyere to measure the coke surface temp. and Tf is obtd. with the prescribed equation.
