Title: Silicon wafer for bonding and manufacture of bonded substrate
Inventor: OI HIROYUKI
IPC: H01L27/12
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing bonded substrate by which wafers can be bonded firmly to each other with less voids. SOLUTION: After two silicon wafers 11 and 12 are cleaned by HF cleaning, the wafers 11 and 12 are rinsed with pure water, cleaned by SC1 (standard cleaning), washed with water, and dried. When the wafer is cleaned by the HF cleaning, oxide films are removed and the surfaces of the wafers 11 and 12 become hydrophobic. When the SC1 cleaning is performed, surface layers are etched and terminal with an OH group. Consequently, the SiOH coverage θon the surfaces of the wafers 11 and 13 become >=40%. After a bonded substrate 13 is obtained by bonding the wafers 11 and 12 to each other at a room temperature, the substrate 13 is heat-treated in a dry oxygen atmosphere. The heat-treating temperature is adjusted to 1,200 to 1,280 deg.C and the heat-treating period is set at 60 minutes. During the heat treatment, Si atoms are terminated with the OH group on >=40% surfaces of the wafers 11 and 12 and the heat- treating temperature becomes 1,200 to 1,280 deg.C. Consequently, the wafers 11 and 12 can be bonded to each other with less voids.

Title: Seat sliding device for automobile
Inventor: FUKATSU YOSHIMI
IPC: B60N2/20
Filed: 1990-05-17
Abstract: PURPOSE:To avoid any contact between a seat back upper end and seat anterior equipment by letting a projecting part formed in a lower end of a seat back supporting arm contact with a guide plate at time of forward movements of a seat cushion, and regulating a front tilting turning angle of the arm as far as a specified angle. CONSTITUTION:At time of forward movements of a seat 13, a cam plate 12 is situated in the upper part of a front part 19a in a horizontal flange part 19 of a guide plate 20. In this state, if a seat back 5 is tilted front and turned round, a projection 12a of the cam plate 12 rotated downward comes into contact with the front part 19a, because the front part 19a is high (because a distance between the cam plate 12 and this part 19a is small), whereby a maximal front tilt turning angle theta of the seat back 5 becomes regulated as far as the specified angle theta' in consequence. Accordingly, an upper end of the seat back 5 will in no case contact or butt to a steering S and suchlike. Moreover, with only a portion (theta-theta') tilted front and turned round in effect, riders are able to board or alight to or from the rear seat with certainty.

Title: Mechanism for inverting recording medium
Inventor: HIBIYA TAKASHI
IPC: G11B7/26
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To obtain a recording medium inverting mechanism capable of inverting the front and the back surface of a disk-like recording medium efficiently by a simple mechanical constitution. SOLUTION: Provided are a cam 7 that is displaced in accordance with the rotation of a holding means for holding a recording medium and a cam follow-up part that vertically moves the holding means following up the displacement of the cam 7 and avoids this holding means so as not to obstruct the inverting operation of the recording medium. A rotating means rotates the holding means and inverts the front and the back surface of a disk. In this case, without performing the rotating operation through the precise control of the rotating means, the cam 7 moves and positions the holding means and the cam follow-up part at their prescribed positions.  In other words, the rotating operation is stopped in a prescribed range without rotating the holding means precisely by 180 degrees and the cam 7 thereby moves naturally, positioning the holding means and the cam follow-up part from the stop position at the time of completion of the rotating operation to the prescribed position and placing the recording medium in the inverted state (inversion of the front and the back surface) precisely by 180 degrees.

Title: Lower/upper extremity blood pressure index measuring apparatus
Inventor: OGURA TOSHIHIKO
IPC: A61B5/0225
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To provide a lower/upper extremity blood pressure index measuring apparatus which, when a lower/upper extremity blood pressure index assumes a normal value, can determine whether or not that value is due to the advanced state of arteriosclerosis throughout the body. SOLUTION: A simultaneous display means 98 displays a mark in a position defined by both a corrected pulse wave propagation velocity PWVc determined by a corrected pulse wave propagation velocity information determining means 92 and an ankle/above-elbow blood pressure index AAI calculated by an ankle/ above-elbow blood pressure index calculating means 96, on a two-dimensional graph consisting of an ankle/above-elbow blood pressure index (=AAI) axis and a corrected pulse wave propagation velocity axis on a display 70. Thus, since the AAI and the corrected pulse wave propagation velocity PWVc are displayed at the same time, when the corrected pulse wave propagation velocity PWVc assumes an abnormal value, the normal value of the AAI can be determined to be derived from the advanced state of arteriosclerosis throughout the body, even if the AAI is a normal value.
