Patent JP-S63270185-A (JP)
Title: Electronic typewriter
Inventor: NARA SHINICHI
IPC: B41J35/14
Filed: 1987-04-30
Abstract: PURPOSE:To enable a multi-color printing, by providing a shift mechanism which shifts the printing ribbon side of a hold device holding a ribbon cassette to a position corresponding to a designated color area of a printing ribbon in printing. CONSTITUTION:A lift motor moves a printing ribbon 21 up and down together with a cassette 22 to move it between a printable position and an unprintable retracted position according to a command. As the printing ribbon 21 is contained in the cassette 22 for a two-color ribbon vertically divided into two colors A, B (e.g. red and black), the height position is selectively controlled so that a printable position can be set either on a position P2 where a lower area A of the printing ribbon 21 is positionally opposed to a type 23a of a type wheel 23 to be stamped or on a position P1 where an upper area B of the printing ribbon 21 is positionally opposed to the type 23a of the type wheel 23 to be stamped. The previous designation of a color area allows a shift means to shift the ribbon cassette which is in a printing state to a position corresponding to the designated color area of the printing ribbon according to the designation to enable a printing at a desired position with a desired color.

Title: Ice-making control method for ice-making machine
Inventor: MASUI KIYOSHI
IPC: F25C1/00
Filed: 1989-04-26
Abstract: PURPOSE:To perform stabilized and accurate ice-making without requiring any adjustments all through the year by constituting an ice-making machine so as to determine an ice-making completion temperature by the temperature decrease time of an evaporator that corresponds to fluctuations of the external air, a condensation temperature and a power frequency. CONSTITUTION:At the time of ice-making, the relational expression of a temperature decrease time corresponding to a temperature zone and an ice-making completion temperature is first memorized in a controller C, and after temperature data have been inputted thereinto, ice-making is started. When a temperature is an evaporator 3b shows about -5 deg.C, the counting of time is started to measure a temperature decrease time when the temperature in the evaporator 3b is lowered down to about -10 deg.C. On the basis of the measured value thus obtained, an ice-making completion temperature is calculated from the relational expression, and this calculation is repeated until the calculated temperature enters to any one of subsequent temperature zones, thereby determining the ice-making completion temperature. The freezing is continued until a measured value from a sensor 4 becomes equal to the value obtained by adding the temperature data to the ice-making completion temperature, and when the temperature is decreased to that level, the ice-making operation is stopped to be shifted to an ice-withdrawing operation.

Filed: 1981-07-10
Abstract: PURPOSE:To reduce the number of elements and increase density without damaging power consumption characteristic by using D-type N-channel transistors and D-type P-channel transistors in a CMOS memory cell. CONSTITUTION:Transistors Tr23, 25 are D-type N-channel transistors and Tr24, 26 are P-channel transistors. To write 1 to this memory cell, a word line 28 is made to high potential to make Tr27 on and open the gate. At the same time, a data line 15 is made to high potential. When voltage v of a memory node 30 is raised to above threshold value of Tr26, Tr27 becomes off and discharge path to voltage Vss is cut off. A stable point A changes to a stable point B and 1 is stored in the node 30. To write 0, the line 28 is made to high potential and the gate is opened. At the same time, the data line 29 is made to 0 potential. Then, voltage v is lowered and Tr26 is made on state. However, Tr23 is made off state. Consequently, the discharge path to voltage Vss is cut off, point B changes to point A, and 0 is stored in the node 30.
