Title: Liquid crystal device
Inventor: OOKI AKIKO
IPC: G02F1/133
Filed: 1988-08-17
Abstract: PURPOSE:To prevent the change in contrast and flickering which arise at the time of driving while temp. compensation is used by controlling a 1st means in such a manner that the fluctuation rate of one scanning selection period changed by a change in an external temp. and the fluctuation rate of a driving voltage amplitude satisfy specific conditions. CONSTITUTION:A microprocessor unit MPU 17 deciphers the voltage value of a temp. sensor 10 which detects the external temp. by an A/D converter 16. The signal thereof is inputted to a voltage controller 18 and a frequency controller 19. The MPU 17 controls a scanning electrode driving circuit 13 and a signal electrode driving circuit 12 in such a manner that the fluctuation rate DELTA1H corresponding to the change in the external temp. and the fluctuation rate DELTAVOP satisfy the equation I. In the equation I, DELTAlog1H=log(1H1+DELTA1H)-log1H; DELTAlogVOP=log(VOP1+DELTAVOP)-logVOP1, where 1H1 is the one scanning selection period before modulation; VOP1 is the crest value of the driving voltage before modulation. The fluctuations in contrast and flickering which are heretofore generated at the time of switching are suppressed in this way.

Title: Cake similar to okoshi (a porous cake made from millet and rice)
Inventor: AKAMATSU KAZUO
IPC: A23G1/00
Filed: 1983-11-01
Abstract: PURPOSE:To produce the titled cake having soft texture as a whole and excellent palatability while keeping the appearance and the basic palatability of the OKOSHI, and formable easily to a desired form, by mixing the raw material of OKOSHI with a specific amount of an oily pastry having specific melting characteristics, and forming the mixture. CONSTITUTION:The objective OKOSHI-like cake can be produced by mixing (A) 1pt.vol. of the raw material of OKOSHI with (B) 0.1-1pt.vol. of an oily pastry melting at about the bodily temperature and solid at about normal temperature, and composed mainly of e.g. laurin-based oil or fat, and forming the mixture to a desired form. The conventional OKOSHI prepared by boiling down a mixture of sugar, starch syrup and water, pouring the liquid to the raw material of OKOSHI, and forming to a desired shape, has hard texture, and the increase in the demand of the OKOSHI is seemed to be difficult in the trend of public to favor a soft texture, and furthermore, since the conventional OKOSHI turns hard irreversibly in a short time in the production process, it cannot be formed to a complicate shape. In contrast to the above, the forming is facilitated by the use of an oily pastry, and a cake having reduced hardness and excellent palatability can be produced keeping the basic appearance and the palatability of the OKOSHI.

Patent JP-2001036276-A (JP)
Title: Thermal louver
Inventor: KURATA KENICHI
IPC: B64G1/50
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To control a heat radiation quantity according to heat radiation surface temperature and to prevent the entry of heat when there is external heat input. SOLUTION: When there is no external heat input, a sense surface 6 radiates heat to become low in temperature, the rotational angle of a stopper ring 11 becomes 90 deg. as shown in (B), and a pivot 10 has no rotational restriction. The rotational angle of a blade 3 varies between 0 and 90 deg. according to the temperature of the heat radiation surface 1 to perform heat control over the heat radiation surface 1. When there is external heat input, the sense surface 6 rises in temperature, the rotational angle of the stopper ring 11 approximates 0 deg. as shown in (C), and the pivot 10 has a rotational restriction in the direction where the blade 3 is opened, thereby suppressing a rise in the temperature of the heat radiation surface 1 due to the external heat input.  A bimetal spring 12 generates a larger force than a bimetal spring 9 because of a difference in width, and, although the temperature of the heat radiation surface 1 becomes high, the blade 3 is not open if the temperature of the sense surface 6 drops, thereby preventing the temperature of the heat radiation surface 1 from rising due to the external heat input.

Abstract: PURPOSE:To take the copy of a desired portion through simple operations, by reading the position of the desired portion in an original by using coordinates for reading original position and inputting the positional data, then, selectively erasing the electrostatic image formed on an image carrier in accordance with the positional data. CONSTITUTION:At the time of copying, an original 1 is placed with its information written surface upward on a coordinate plate 27 for designating original position by setting the original 1 to a previously fixed reference point M and X and Y coordinate reference lines. Then coordinate scales of two corner points a(Xa, Ya) and b(Xb, Yb) which define a portion G to be copied of the original 1 are read. After reading the coordinate scales, the coordinate values are inputted by operating ten keys 28 of an operating section 31 and after the position of the portion G to be copied is designated, the original 1 is placed on an original placing table 2 with its information written surface downward. When this copying device is operated in the same way as ordinary copying operations thereafter, the erasion controlling signal of an erase lamp 26 is outputted from a control circuit 33 in accordance with the data of the portion G to be copied. Thus unnecessary portions are erased and only a necessary portion is copied.
