Title: Optical scanning type measuring apparatus
Inventor: KUWABARA YOSHIHARU
IPC: G01B11/02
Filed: 1987-08-07
Abstract: PURPOSE:To eliminate a time deviation between both parallel scanning beams, to remove the effect of vibration and to measure the sizes, by directing a compensating parallel scanning beam toward a material to be measured in approximately parallel with a measuring parallel scanning beam, and performing the scanning at the same time in synchronization with the reverse scanning direction. CONSTITUTION:A laser light source 10, a collimator lens 18, a condenser lens 22, a measuring photodetector 26, a preamplifier 28, a segment selecting circuit 30 and a display device 38 are provided. A measuring parallel scanning beam 20 is scanned in the direction Y in an optical scanning type measuring apparatus. In this apparatus, a tuning fork deflector 50 is used in place of a rotary polygonal mirror. Thus, the measuring parallel scanning beam 20 and a compensating parallel scanning beam 52, which is scanned in synchronization with the reverse direction of the beam 20, are formed. The beams are condensed into the measuring photodetector 26 and a juxtaposed compensating photodetector 66 through the condenser lens 22. Thus detected signals P1 and P2 are obtained in a measuring circuit 67. Parts of vibrating scanning beams 56 and 60 are separated with half mirrors 70 and 72. The position of the center of gravity is directly measured with PSDs 74 and 76, and the accuracy is enhanced.

Title: Wafer cleaning method
Inventor: ITANI NAOKI
IPC: H01L21/304
Filed: 1994-07-29
Abstract: PURPOSE:To provide a wafer cleaning method wherein the resticking of foreign matter is prevented and favorable cleaning results are obtained. CONSTITUTION:A plurality of wafers 1 are immersed in cleaning liquid 5 in a cleaning bath 4, and each wafer 1 is thereby cleaned. In this process the wafers l are paired, and each pair 10 is placed in a wafer carrier 2 in such a manner that the back sides 12 of the wafers 1 are in contact with each other. Thus the back sides 12 of the wafers 1 are virtually kept away from contact with the cleaning liquid 5 during cleaning. This prevents foreign matter from being produced from the back sides 12 of the wafers, and thus such foreign matter from re-sticking to the front sides 11 of wafers. As a result only the front sides 11 of the wafers are cleaned in the cleaning liquid.

Title: Thermal recording method
Inventor: SATO KOJI
IPC: B41M5/398
Filed: 1984-09-21
Abstract: PURPOSE:To enable inexpensive thermal recording forming an image stable to light and a chemical substance and having good storage stability with good thermal sensitivity, by heating a medium, which is formed by coating a base material with a substance changing in its stickiness by heating, on the basis of electrical input information and subsequently forming a visible image by toner development. CONSTITUTION:A base material is coated with a substance of which the stickiness increase for a definite time under heating. As the substance melted under heating and holding a liquid state at temp. of m.p. or less for a definite time, benzotriazole or acetanilide can be designated. Thus obtained recording paper is recorded under heating by a thermal head or a hot pen. Because only the surface stickiness of the recording paper may be changed, recording energy may be 1/2-1/5 that of conventional recording paper. Because of this, a recording time is short and the miniaturization of the power source for driving a thermal head is enabled and the apparatus can be miniaturized and reduced in its wt.

Filed: 1983-10-24
Abstract: PURPOSE:To prevent degradation of engine performance, by judging whether regeneration of a particulate capturing filter was successful, and prohibiting filter regenerating operation temperarily in case that the regeneration was unsuccessful. CONSTITUTION:In operation of an engine 1, judgement is made from the difference of the output signals of pressure sensors 7A, 7B disposed on the opposite sides of a filter 3 for capturing particulates contained in exhaust gas whether the amount of particulates captured by the filter 3 has reached a prescribed value.
