IPC: C08F8/12
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a recyclable polymn. catalyst and a process whereby a vinyl polymer can be produced inexpensively. SOLUTION: This catalyst is a mercapto compd. having a wt. average mol.wt. of 1,000 or higher or is a mercapto compd. having at least 10 mercapto groups in the molecule and is obtd. e.g. by reacting a halogen compd. with a hydrosulfide to substitute a halogen atom of the halogen compd. with a mercapto group.

Title: Multiple virtual storage system
Inventor: NAKAMURA HIROSHI
IPC: G06F12/08
Filed: 1982-04-30
Abstract: PURPOSE:To improve the efficiency of usage of an address space and a TLB (conversion index buffer mechanism), by arranging a system common section and a user specific section freely on an address space in the segment unit. CONSTITUTION:When the user is changed and the address space is changed over, a PTLBU instruction is issued. An entry ineffective circuit 16 is started with a specific decode signal DEC of the PTLBU instruction, and the effective/ineffective designation bit V of an entry where the system/user definition bit S/U in each entry of a TLB15 is logical ''1'' is all updated into logical ''0''. Thus, among all the entries of the TLB15, only the entry where a conversion information pair corresponding to the user specific segment is stored in the entire entry of the TLB15 is made ineffective state selectively. Thus, even after the user replacement, the entry where the conversion information pair corresponding to the system common segment in the entire entry of the TLB15 is stored is used effectively.

Title: Manufacture of bipolar transistor
Inventor: GOTO HIROSHI
IPC: H01L21/331
Filed: 1988-03-29
Abstract: PURPOSE:To realize a high-speed lateral bipolar transistor high in breakdown strength by a method wherein a mask is employed for the introduction of impurities of both first and opposite conductivity types for the formation of a laterally extending thin base region using the difference in lateral diffusion between the two impurities and both ends of the region are respectively converted into a source and drain. CONSTITUTION:An SiO2 film 2 is formed on a silicon substrate 1, a P-type silicon layer 3 is formed and patterned, and then a thick oxide film 4 is formed. Next, the oxide film 4 is subjected to patterning, after which a thin oxide film 5 is formed. Boron and phosphorus ions are implanted through the oxide film 4 serving as a mask, and then annealing is accomplished. When the doze of boron implanted is larger than that of phosphorus in said process, a region 6 of the p-type silicon layer 3 not covered by the masking oxide film 4 will be a P<+>-type region and, due to lateral diffusion, an N-type region 7 will be formed a little inside the edge of and under the masking oxide film 4. In this way, a microstructural P-N-P type lateral bipolar transistor is obtained, capable of enhanced integration, increased speed, and improved breakdown strength.

Title: Ophthalmologic operation device using foot switch
Inventor: SUZUKI TATSU
IPC: H01H35/34
Filed: 1988-03-29
Abstract: PURPOSE:To permit an operation to be safely performed, even when a foot switch is moistened by water or the like, by connecting the foot switch to a main unit by a fluid transmitting part and determining a control quantity of an ophthalmologic operation device by a control quantity determining part in accordance with a pressure of fluid transmitted by the fluid transmitting part. CONSTITUTION:A foot switch 40 is connected to a processing part 41 through a fluid transmitting part 8, and a pressure of air in a cylinder part 54 increases corresponding to a step-in amount of a step-in part 51. A change of this pressure of air is transmitted to a side of a pressure sensor 160 through the fluid transmitting part B. The processing part 41 converts the change of air pressure into an electric signal corresponding to the step-in amount, and a control part 42 calculates this electric signal, feeding a control signal to a suction part 1. The suction part 1 sets a cutter 5 for its suction amount being based on the control signal. While a pressure in a terminal end part 104 increases, when a pressure sensor 161 detects this pressure increasing, an on-signal from the processing part 41 is given to the control part 42, and it outputs a cutter driving control signal to a cutter driving unit 2, driving the cutter 5. Thus, the cutter 5 enables its driving and suction to be simultaneously performed.
