Title: Photocatalytic coating, photocatalyst coated thereby, photopermeable base material coated with photocatalytic coating film, and lighting unit using photopermeable base material
Inventor: MATSUNO KENJI
IPC: B01D53/86
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To substantially improve photocatalytic activity by increasing the exposure surface area of photocatalytic particles forming a photocatalytic coating film. SOLUTION: A coating film 530 containing a photocatalyst of titanium oxide or the like and a binder 110 containing silicon oxide is formed on the surface of a base material 51 having light permeability e.g. a sheet glass or a plastic plate according to a routine process. Next, the coating film 530 is subjected to an alkali treatment using an aqueous sodium hydroxide solution or the like and/or an acid treatment using a hydrofluoric acid or the like to form a photocatalytic coating film 100 on the base material 51, and thus a cover material (a photopermeable base material) 50 is obtained. The silicon oxide contained in the binder 110 is eluted and removed by the alkali and/or the acid treatment, so that the exposure surface area of the titanium oxide particles 101 is increased and thereby the activity of the photocatalyst is substantially enhanced.

Title: Method and device for detecting abnormal operation of reciprocating body
Inventor: NAKAJIMA TADASHI
IPC: B30B15/00
Filed: 1981-08-07
Abstract: PURPOSE:To detect the abnormal operations of a reciprocating body with good accuracy by  setting permissible positive and negative change values of dead center values from the values  actually measured beforehand, and comparing the rate of change in the dead center values  operated from the detected dead center values with set values. CONSTITUTION:In the period when a reference value is set, the movement of a reciprocating  body is detected with a magnetic sensor or the like and dead center values are detected at  every reciprocating motion and the values are stored. From the stored values, the max. positive  and negative values in the rate of change of the dead center values before and after the same  are operated, and a desired allowance value is added thereto, whereby permissible positive  and negative change values are set and the values are stored. In the period when abnormality  is detected, the dead center values of the reciprocating body are detected and stored at every reciprocating motion thereof, and from the stored values thereof the rate of change in the dead center values is operated and is compared with the set values of the above-mentioned permissible positive and negative change values. When the rate of the change is larger, abnormality  is displayed. Since the changes owing to external factores are removed from the above- mentioned set values, small abnormality is detected with good accuracy.

Title: Wire bonding device
Inventor: KAWABATA KAZUHIRO
IPC: H01L21/60
Filed: 1989-05-17
Abstract: PURPOSE:To make a drive circuit effective only during bonding by providing a CPU to a controller to operate the drive circuit and giving commands to feed wires after setting an actuator to a state of operation. CONSTITUTION:When a state feeding wires is obtained by controlling a CPU 2 in a controller 1, for example, instructions are given to a drive circuit 3 only when its operation is incorporated into bonding sequence. Then the sensing state of a touch sensor 5 makes an actuator 4 operate. And during the stopping of bonding, the CPU 2 makes the drive circuit 3 become ineffective compulsorily. In this way, the circuit 3 becomes effective only when bonding is in operation and the actuator 4 feeds the wires. This step prevents wastage of the wires and saves the time required for repairs due to a loose and careless operation, and stable feeding of the wires is performed.

Filed: 1988-05-20
Abstract: PURPOSE:To obtain an appropriate system which is used for a private school system by classifying numbers of terminals as a master terminal and slave terminals and making 1:n connections for the master terminal and 1:1 connections for the slave terminals. CONSTITUTION:One terminal 1A is regarded as the master (center) terminal and remaining terminals 1B, 1C,... are regarded as the slave terminals. Then the respective terminals 1B, 1C,... are connected to the center terminal 1A to make 1:n (multi) connections for the center terminal and 1:1 connections for the slave terminals. The 1:n connections are therefore used to multi-address the same data from the center terminal 1A to the respective terminals 1B, 1C,.... Further, data sent from salve terminals are stored in corresponding slave terminal areas of individual memories 55 of the center terminal and displayed on the monitor of the center terminal, so they are neither sent directly to other slave terminals nor displayed on the monitors of the slave terminals. Consequently, the handwriting system for a private school is obtained.
