Abstract: PROBLEM TO BE SOLVED: To efficiently produce poly(p-t-butoxystyrene) by polymerizing p-t- butoxystyrene in the presence of an organometallic compound in a mixed solvent comprising a hydrocarbon solvent and a (poly)alkylene glycol diether. SOLUTION: p-t-Butoxystyrene is polymerized in the presence of 10-5-10-3 mol (per g of p-t-butoxystyrene) of an organometallic compound as the polymerization initiator in a mixed solvent comprising a hydrocarbon solvent and 0.05-10 wt.%, preferably 0.2-5 wt.%, (poly)alkylene glycol diether of the formula: R1(OR2)nR3 in a high vacuum or an inert gas atmosphere at -50 to 0 deg., preferably -40 to 0 deg.C, for 10 min to 20 hr. Then, the polymerization is stopped by adding a polymerization stopper such as water or methanol. The reaction mass is then washed with water, and the solvent is removed by distillation. In the formula, R1 and R3 are each lower alkyl; R2 is lower alkylene; and n is 1-5.

Filed: 1992-03-30
Abstract: PURPOSE:To reduce operation by an operator at the time of executing copying action so as to lighten the work load of the operator by detecting that an original platen cover is opened and synchronously and automatically releasing a preheated condition.

IPC: H04N1/00
Filed: 1987-03-25
Abstract: PURPOSE:To correct and change a program without requiring manual operations by automatically receiving and storing an update operation instruction on a magnetic disk and loading the update operation instruction to a main memory to execute it. CONSTITUTION:A CPU 7 sets the execution address to the start address of a ROM 4 and fetches a preliminarily stored transfer operation instruction from the ROM 4 and executes it. That is, the CPU 7 sets an initial value to a counter 14 and outputs a read signal RD to a disk control circuit 12; and when the disk control circuit 12 transfers the update operation instruction from the magnetic disk 13 to a RAM 11 and outputs a read operation completion signal RN, the CPU 7 detects this signal RN to increase contents of the counter 14 by one and transfers contents of the RAM 11 to a RAM 5. Simultaneously, the write address to the RAM 5 is set to a counter 6, and contents of the counter 6 are updated at each time of write to the RAM 5. Thus, the CPU 7 performs the facsimile communication controlled by the program which is corrected or changed by the update operation instruction.

Abstract: PROBLEM TO BE SOLVED: To secure a large space in a stable manner under the eaves of a T-shaped gate electrode, to reduce a parasitic capacity of a gate, and to achieve a low minimum noise index and high gain, by controlling the filling of an insulation film under the eaves of the T-shaped gate electrode. SOLUTION: First insulation films 4 are formed in the vicinity of eaves 7a of a T-shaped gate electrode 7. Upon forming a second insulation film 8 the formation thereof is suppressed under the eaves 7a so as to reduce the filling of the second insulation film 8 between the first insulation films 4 and the eaves 7a. Thus, it is possible to secure large spaces 9 in a stable manner under the eaves 7a of the gate electrode 7. Moreover, with the spaces 9, it is possible to reduce a parasitic capacity of the gate electrode 7 so as to achieve a low minimum noise index and high gain. Further, the surface of an activation layer 2 in a recess 6 is protected by the insulation layer 8 so as to cause no problem of reliability that includes fluctuations of a gate pressure.

Abstract: PROBLEM TO BE SOLVED: To realize recording material conveyance of high accuracy without applying extra load at the time of conveying recording material by providing a carrier path with a carrier guide formed of conductive material so as to guide the conveyed recording material in sliding contact. SOLUTION: U-shape carrier guides 9a, 9b are conveying means for picked-up recording paper S and are provided to guide the recording paper S to a pair of carrier rollers 10.

Title: Amplitude converting circuit for logical signal
Inventor: DOUSEKI TAKAKUNI
IPC: H03K19/003
Filed: 1985-04-05
Abstract: PURPOSE:To execute the expected action even when the temperature of the semiconductor logic circuit rises by connecting serially the first channel type electric field effect transistor, a diode circuit, and the second channel type electric field effect transistor between the first and second electric power source terminals. CONSTITUTION:When a small amplitude logic signal SB is obtained by a high electric potential VBH from an output terminal 4, the resistance of a diode 21 is decreased as the temperature rises, and therefore, the drop voltage of a diode circuit D1 is decreased as the temperature rises, and the value of the high electric potential given to the gate of the electric field effect transistor Q3 is increased as the temperature rises. Consequently, the voltage between the gate of Q3 and the source connected to an electric power source terminal E1 is decreased, the temperature dependency of the shifting degree of the carrier (electron) is a little only influenced by the temperature dependency of the drain electric current, and the value of the high electric potential VBH is increased as the temperature rises. Thus, the high electric potential VBH is obtained by having the value of the allowable scope of the high electric potential VCH of a small amplitude logic signal SC handled at a semiconductor logic circuit C, and even when the temperature rises, the expected action is executed.

Title: Controller for linear motor driven rotating mechanism
Inventor: KAKINUMA YOSHIKI
IPC: H02K7/116
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent the advantage of a rotating mechanism from being spoiled, by braking the rotating section of the mechanism with low acceleration when abnormality occurs, and, at the same time, by setting the rotating section to a non-contact state in a normal state by stopping a rotating structure when the detected speed of an angle detector which detects the rotation of a gear wheel exceeds a fixed value. SOLUTION: The rotation of a gear wheel 11 is detected by means of an angle detector 15. When the detected speed of the detector 15 exceeds a preset value, a motor 14 is stopped and the tooth face of the wheel gear 11 comes into contact with that of a pinion gear 12, and the rotation of a lens-barrel 3 which is a rotating structure is stopped by using the inertial force of a speed reducer 13. Therefore, in such an abnormal case where power supply is interrupted due to a power failure, etc., the rotation of the lens barrel 3 can be stopped by using the inertial force of the speed reducer 13, because the lens barrel 3 is rotated by its own unbalance moment.
