Title: Production of particulate dispersed composite
Inventor: SAYO KOICHI
IPC: C08J3/20
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to disperse a metal and metal oxide which are formed to a particulate form into a matrix material at high concentration by dissolving the composite prepared by dispersing the particulates of the metal and metal oxide in the matrix material into an alcoholic solvent and removing the matrix material not bonding the particulates. SOLUTION: In the case of production of the concentrated particulate dispersed composite, the composite 10 is formed in the state that the particulates 9 of the metal and metal oxide are held by the matrix 13 consisting of an ambient oligomer or high molecular material. When the composite is rested after an alcohol solvent is put into the composite 10 and is stirred, a liquid part 11 and precipitate 12 are separated. Since the matrix 13 not bonded to the particulates 9 of the metal and metal oxide is included in the liquid material 11, this matrix is removed and only the precipitate 12 is taken out. This precipitate 12 consists of the matrix 13b bonded to the particulates 9 of the metal and metal oxide and is the concentrated particulates dispersed composite 15. This concentrated composite is usable as raw material for catalysts, or the like.

Title: Adhesion-free cap-ring
Inventor: DANIERU EI PITSUKERERU
IPC: F16J15/10
Filed: 1989-05-12
Abstract: PURPOSE: To easily remove a cap from a valve body member even after a long time elapses, by causing a semi-rigid material to creep after the cap is fastened to the body member so as to enable the thread of the cap to be loosened from the body member. CONSTITUTION: A cap member 20 is fastened until it makes contact at its shoulder 30 with an abutting ring 24 which is semi-rigid so as to exert its slight compression to the shoulder 30, but which is hard, sufficient to maintain a clear stop position which a worker who fastens the cam member 20 onto a valve body member 12 can easily note. Once the cap is fastened, sealing is effected between the cap member 20 and the valve body member 12 so as to seal an interior cavity 16 against gaps 50 extending into threaded parts 26, 28. Further, the plastic semi-rigid ring 24 tends to creep so that vertical force is effected among the shoulder 30, and shoulders of the ring 24 and the cap member 29, thereby it is possible to reduce sticking force effected between threaded parts 26, 28.

The controlling part 46 outputs a controlling signal to a driving signal generating circuit 40 according to the deviation from the target value of a measuring force and also generates a pulse signal for counting corresponding to the rotary angle of the step motor 10, namely, the displacement of a spindle 22 according to the driving signal. The pulse signal thereof is counted by a counter 50 and the displacement of the spindle 22 is found.

Title: Inter-computer communication control system
Inventor: NISHIYAMA TAKESHI
IPC: H04L12/40
Filed: 1991-05-23
Abstract: PURPOSE:To reduce the transmission quantity and the transmission time by integrating two packets sent to the same node into one packet. CONSTITUTION:When a transmission data to a node 2 is produced, a sender source node 1 generates a packet and confirms that other packet is not sent to a communication line 3 and sends the packet. Upon the receipt of an acknowledge ACK signal from the node 2, the packet transmission is finished and the succeeding processing is implemented. However, when no ACK signal comes from the node 2, the packet is retried in the node 1. The node 1 checks whether or not a succeeding transmission data is generated for that time and checks a transmission destination of the data when generated. As a result, when the data is a data to the node 2, the data is jointed with the retried data and the packet is generated as one data and it is sent. Thus, the data quantity is saved and the transmission efficiency is improved.

Abstract: PURPOSE:To obtain a photoreceptor having high sensitivity by an easy method by treating a charge generating material which constitute a charge generating layer with a chlorine-base org. solvent. CONSTITUTION:The charge generating material which constitutes the charge generating layer is treated with a chlorine-base org. solvent.
