Inventor: MATSUMOTO SHOICHI
IPC: C08F120/16
Filed: 1992-11-06
Abstract: PURPOSE:To separate the subject isomers in high purity by dissolving the cis- isomer and the trans-isomer of an ester of methacrylic acid and an alkyl- substituted cyclohexyl alcohol in a solvent. CONSTITUTION:An ester of methacrylic acid and a cyclohexyl alcohol derivative having 4-8C alkyl group as a substituent at the ortho, meta or para-site of hydroxyl group is dissolved in a solvent such as benzene.

Title: Thermal hysteresis control device for thermal head
Inventor: KANBE YUKIHIKO
IPC: B41J2/38
Filed: 1994-12-26
Abstract: PURPOSE: To prevent deterioration of printing quality and make control of energization simple by suppressing a temperature of a thermal head near below a lower limit temperature of coloring for a thermosensible paper when printing is not effected. CONSTITUTION: A head temperature controller 7 effects energization for respective heating elements of a thermal line head 4 for a short period of time on the basis of an energization pulse to control a temperature resulted from a remaining heat of a thermister 5 to 55 deg. which is below a lower limit temperature of coloring for a thermosensible paper. Since a temperature of the head is always kept at substantially 55 deg., a temperature rise of the heating elements required for effecting coloring of the thermosensible paper is around 10 to 20 deg., so that a small amount of energy for energization suffices. In this manner, energization never starts on the heating elements with a head temperature low, so that any excessive electric current does not pass through the heating elements.  Accordingly, the head is not subjected to excessive stress, and so there is not a fear of the head becoming short in life. In addition, it is possible to prevent deterioration of printing quality and make control of energization simple.

Title: Hot and cold water mixer
Inventor: YONEKUBO HIROAKI
IPC: F24D17/00
Filed: 1989-12-13
Abstract: PURPOSE:To make it less restricted to locate a valve for mixing hot water and cold water, motor, and the like, enable changing the temperature of mixed water in a much shortened time, and preclude the danger of supplying scalding-hot water by a method wherein an electrical driving means is controlled by comparing signals respectively from a temperature-setting device and a temperature sensor. CONSTITUTION:An instruction for hot-water supply given by a temperature-setting device 26 causes solenoid valves to open, the supply of hot water and cold water thereby being started. A controller 19 is preset for a temperature in ordinary use, the instruction being executed, for example, at 40 deg.C. If the temperature detected by a thermistor 25 is lower than 40 deg.C as in the presetting, the controller 19 controls a ratio-control valve 18 in such a manner as to increase the flow rate of hot water and decrease that of cold water. If, contrarily, the detected temperature is higher, the control acts to decrease the flow rate of hot water and increase that of cold water. Hot water and cold water are accordingly mixed at a junction 24 and the mixture is supplied through a supply outlet 27. This method enables locating the junction 24 of the two streams and the supply outlet 27 close to each other, permits installing the ratio control valve 18 at any arbitrary location, enables quickly changing the temperature of the mixed water as desired, and precludes the danger of scalding due to release of hot water from stoppage.
