Title: Production of 1,4-benzenethiol
Inventor: TAKAHASHI MASAHIDE
IPC: C07B61/00
Filed: 1986-12-27
Abstract: PURPOSE:To safely obtain 1,4-benzenethiol in a simple process, by reacting thiophenol or diphenyl disulfide with sulfur chloride in the presence of a catalyst and reducing the resultant product. CONSTITUTION:Thiophenol or diphenyl disulfide which is an oxidation product thereof is reacted with sulfur chloride in the presence of iodine or a Friedel- Crafts reaction catalyst, e.g. zinc chloride, in a solvent, e.g. chloroform, etc., at room temperature - boiling point of the solvent and the resultant product is then reduced with zinc and hydrochloric acid to afford the aimed substance. The reaction is carried out by using the Friedel-Crafts catalyst and iodine in a molar amount of 0.05-2 times based on the thiophenol. The obtained substance is useful as a material for highly functional engineering plastics having excellent heat and chemical resistance or raw material for producing sulfur- containing polymers useful as a material for organic glass having a high refractive index utilizing high atomic refraction of the sulfur.

Title: Bridge device
Inventor: ONODA MINORU
IPC: H04L12/28
Filed: 1991-11-29
Abstract: PURPOSE:To improve a data transfer efficiency at the time of a packet retransmission by abolishing successively packets in a low priority order. CONSTITUTION:The transfer priority information of each data station is added and registered in a transfer data base 25 and the packet transmitted from the data station whose priority is the lowest among the packets waiting transmission is selected according to the priority information. Then, the selected packet is abolished so that the overflow state of a buffer memory 24 can be canceled. Thus, as the data station is farther positioned from a bridge device 20, the transfer priority of the packet is set higher, so that the packet transmitted from the near data station whose retransmission is relatively easily attained can be previously abolished. Thus, the data transfer efficiency at the time of the packet retransmission can be improved.

Title: Device for monitoring blocking of filter layer of gravity filtration apparatus
Inventor: NAKADA KIMIMICHI
IPC: B01D29/88
Filed: 1987-12-14
Abstract: PURPOSE:To confirm easily blocking condition of a filter tank and to eliminate the requirement for mechanically movable parts by providing a water sealing column communicated with an air tank formed at the top of an inverted U-shaped pipe and sealed with water at the bottom end, thus enabling detection of an internal liquid level of the water-sealed column. CONSTITUTION:The amt. of air sucked by a sucked air amt.-control mechanism 10 is restricted gradually by the rise of the level of feed water accompanying the progress of blocking of a filter tank 2. Thus, the air pressure of the air tank at the top of a siphon tube 7 becomes gradually negative. Filtered water in a water-sealed tank 34 rises gradually to the inside of the water-sealed column 31 by the effect of atmospheric pressure depending on the condition of the negative pressure generated in the air tank. When in this case, the water- sealed column 31 is made of a transparent pipe, the extent of blocking of the filter tank 3 can be confirmed by observing visually the liquid level of the water-sealed column 31.

Filed: 1992-10-30
Abstract: PURPOSE:To provide a data multiplex circuit in which a delay amount can be reduced by generating a signal whose phase is matched with the phase of data from a data generating circuit, and generating a multiple clock according to it. CONSTITUTION:A data generating circuit 1 generates a reference signal 1B suited to the output of the data. The reference signal 1B is compared with a multiple clock 5A by a comparator circuit 2, the output is converted into a reset signal 3A by a phase difference by a control circuit 3, and a multiple frequency-dividing circuit 5 is reset. The reset of the multiple frequency-dividing circuit 5 is repeated until the phase is matched with the data output of the data generating circuit. That is, the multiple clock 5A of the frequency-dividing circuit 5 inputted to a multiplex circuit 4 is relatively phase-matched with the delay of the data generating circuit 1 by resetting the frequency-dividing circuit 5. The multiple clock 5A and a retiming clock 7A are not necessarily absolutely matched with the phase of the data generating circuit, and the data can be multiplexed by an arbitrary frequency.

Abstract: PURPOSE: To largely improve injection rate and lower inertia of a deceleration transfer system so as to improve responsivity by using an AC servo motor whose specified maximum rotational speed is guaranteed as an injecting electric servo motor, in an in-line screw type injection molding machine. CONSTITUTION: In a plasticizing/measuring process, a screw 3 is rotated by a measuring motor 12 through a timing belt 15 and a resin material is stored in the front part of the screw 3 by kneading and plasticizing it.

Filed: 1988-12-15
Abstract: PURPOSE:To drive a bipolar transistor(TR) sufficiently by providing a p-channel MOS TR for base charge extraction of an npn bipolar TR for pullup so as to swing an output high level fully. CONSTITUTION:When a base potential of a TR Q1 is lower in the pullup while an output level is pulled up by the npn bipolar TR Q1, the impedance with the p-channel MOS TR Tpu for base charge extraction is high and the current is almost a base current of the TR Q1. When the output level is pulled up, the impedance of the TR Tpu is low and the output level is pulled up to Vcc by the current path of p-channel MOS TR Tp-Tpu. Thus, the output high level is subject to full swing up to the Vcc and the bipolar TR is sufficiently driven.
