Title: Instrument for measuring activity of carbide coating treatment bath
Inventor: KAJINO MASAKI
IPC: G01N27/30
Filed: 1984-12-13
Abstract: PURPOSE:To measure easily the decreased activity of a carbide coating treatment cell by subjecting preliminarily only one of a pair of electrodes constituting a detecting part to carbide coating. CONSTITUTION:The detecting part 1 consists of a pair of the electrodes 11, 12 consisting of piano wires and a carbide layer 13 similar to the carbide coating by the bath to be measured is coated on one electrode 11 thereof. The upper parts of the respective electrodes are coated with protective pipes 3 made of ceramics. The surface condition of a pair of the electrodes is different in the beginning when a pair of such electrodes are dipped into the bath 5 to be measured and therefore a potential difference is generated between the electrodes. The carbide layer by the bath to be measured is thereafter formed also on the electrode which is not subjected to the prior carbide coating so that a pair of the electrodes have the same surface condition. The potential difference is therefore converged to zero. The change at which the potential difference is converged to zero is observed by a measuring part 2 and the activity of the bath 5 is evaluated.

Title: Optical disk driving device
Inventor: YAMADA SEIJI
IPC: G06F3/08
Filed: 1994-10-28
Abstract: PURPOSE: To reduce the size and cost of a device by using a reflection type photosensor as a means for reading bar codes. CONSTITUTION: An optical disk 1 is rotated and the bar code region 4 of the optical disk 1 is irradiated with the light emitted from a light emitting element 6 of the reflection type photosensor 5. The reflected light from the bar code region 4 is received by a photodetector 7 and an output signal is outputted from an output terminal. This output signal is strong in the space parts of bar codes 4c and weak in the bars and, therefore, the reading of the bar codes 4c by identifying the space parts and the bars is made possible by detecting the various intensities of the output signals. Since the reflection type photosensor 5 is small in size and low in cost, the size and cost of the optical disk driving device are reduced. The reflection type photosensor 5 is preferably fixed to a fixing part for holding a spindle motor.
