Title: Production of 4-tert.-butylcatechol
Inventor: SAITO TAKAYUKI
IPC: C07B61/00
Filed: 1993-09-14
Abstract: PURPOSE:To permit continuous and efficient production of the title compound which is useful as a polymerization-inhibitor through a flow process where catechol and inexpensive isobutylene oligomers free from the high-pressure gas regulation laws are brought into contact with a solid acid catalyst. CONSTITUTION:A mixture of catechol and isobutylene oligomers such as di- isobutylepe is brought into contact with a solid acid catalyst such as silica- alumina at 140 to 250 deg.C under pressure of 2 to 10 kg/cm<2> to give the objective 4-tert.-butylcatechol. The catalyst is preferably a synthetic silica-alumina containing 10 to 40wt.% of alumina. The oligomers are preferably dimer to pentamers isobutylene, particularly diisobutylene. The isobutylene oligomers are used in an amount of 0.5 to 2 moles per mole of the catechol.

Title: Microcomputer device
Inventor: KAWADA KAZUHIDE
IPC: G06F11/28
Filed: 1984-11-28
Abstract: PURPOSE:To monitor the specific contents of a data memory while allowing real time operation by outputting the contents of a specified RAM to the external in a machine cycle in which a CPU does not use a data bus. CONSTITUTION:In the machine cycle in which the data bus 2100 is not used, the CPU1 outputs logical '1' to a control line 1000. Receiving the output, a multiplexer 3 supplies an address supplied through a monitor address input line 3000 as an address specification signal of a data memory 2. Consequently, the contents of the address in the specified memory 2 are latched by a data register 4. Thereby, the data on the specified address in the memory 2 are latched by the register 4 every appearance of the machine cycle in which the CPU1 does not use the bus 2100 by supplying the address specification signal from the external through the line 3000. Thus, whether the contents of the memory 2 are changed or not can be checked by reading out the contents of the register 4 while referring the signal on the line 1000.

Title: Grinding method
Inventor: NISHIO KIYOSHI
IPC: B24B49/02
Filed: 1986-10-21
Abstract: PURPOSE:To prevent the ground surface of a work from being damaged, by making each detecting measurer of in-process gauges go up at the aiming size left behind as much as slight residual size against the specified finishing size, while letting a grindstone infeed as far as the residual size. CONSTITUTION:During the grinding, a ground surface height position H1 of a work 6 and a chuck surface height position H2 of a chuck table 7 are measured each at every moment by both in-process gauges 11 and 12, and thickness size of the work 6 during the grinding is detected from the subtracted value of these detected values at an operational part 13. Infeed motion of a grindstone 8 is controlled by in-process control till this detected value comes the aiming size left behind as much as slight residual size against the preset work finishing size. Afterward, each detecting measurer of these in-process gauges 11 and 12 made to go uo and the inprocess control is finished. Simultaneously, the infeed motion of the grindstone 8 is controlled as much as an infeed rate equivalent to the residual size delta to the extent of finishing size S1. In consequence, a ground surface of the work 6 fully ground to the finishing size S1 is in no case damaged by the detecting measurer and its sticking chips.

Abstract: PURPOSE:To efficiently produce a large-diameter material by sealing powder into a malleable container, heating the powder and inserting said container into a cylinder so as to provide a spacing between the container and the inside wall of the cylinder, then compressing the powder. CONSTITUTION:The metal powder or powder mixture 7 composed of a metal and nonmetal is packed into the cylindrical container 6 made of, for example, a mild steel and the container is sealed after the inside thereof is evacuated to a prescribed vacuum degree. This container is compressed by a cold isostatic press and thereafter, the container 6 is inserted into the cylinder 1 by providing the spacing 8 between the inside wall of the cylinder and the outside wall of the container. A stem 4 is then advanced to compress the container 6. The container 6 is thereby brought into tight contact with the inside surface of the cylinder 1 and the powder 7 is compressed. The pressing pressure of the stem 4 is further increased to annihilate the grain boundaries of the powder. A solid metal 9 is thus obtd.

Title: Cap insertion device
Inventor: KON SHINICHI
IPC: H02G15/02
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To enable easy insertion of a wire into a cap by locking the end of the wire accomodated in a tentative holding part, thereby allowing the cap inserted by a set pin to be released therefrom, and releasing the locking at the time when the wire is inserted into a through hole of the cap. SOLUTION: In a step that a high tension cable 500 is inserted into a through hole part of a cap 600, a connection terminal 510 constituting an end of the cable 500 is locked by a tentative holding part 730 of a set pin 20 by means of a locking pawl 22 of locking means. Accordingly, even if the cable 500 receives a stress from the cap 600 to remove from the pin 20, hand shaking does not occur to thereby generate no dislocation in the terminal 510 of the cable 500. Thus, it is possible to implement sure insertion work with good yield and without requiring skill. By advancing a drive pin 31 to tilt the pawl 22 to thereby disengage an engaging part 22A, the cable 500 integrated with the cap 600 can be taken out.
