Title: Hand protector for thin substrate transfer system
Inventor: KIRIHATA TADASHI
IPC: H01L21/677
Filed: 1995-04-18
Abstract: PURPOSE: To obtain a protector for facilitating the installation work of each unit by constituting a hand of a hand body and a hand position detection means disposed at the forward end of the hand body thereby protecting the hand body against an obstacle during transfer of a thin substrate. CONSTITUTION: A hand 5 for transferring a thin substrate contained in a cassette comprises a hand body 5a, and a hand position detection means 6 disposed at the forward end of the hand body 5a. For example, a phototube sensor 6 comprising a reflective beam switch is embedded at one position at the forward end of the hand body 5a. When an obstacle 10 appears during transfer of the hand 5 and the distance between the phototube sensor 6 and the obstacle 10 becomes shorter than a predetermined distance, the hand body 5a receives a stop signal from the phototube sensor 6 and stops the operation of transfer system before the obstacle 10 interferes with the hand body 5a.

Title: Induction device
Inventor: YASUDA KENTAROU
IPC: G05D1/12
Filed: 1981-06-16
Abstract: PURPOSE:To stably control the advancing direction of a body to be induced, by finding variations of the optical axis of the optical system of the induction device and the speed of the  angle of rotation of a target image in optical images. CONSTITUTION:A two-dimensional image formed by an optical system 2 is taken by an image  pickup tube 3, and the image is photoelectrically converted by scanning the photosensitive p lane of the pickup tube 3 with a horizontal scanning signal (a) and a vertical scanning (b) from a scanning signal generator 4. The dark point of the output of the pickup tube 3 is detected 5 and 6 and sample-held 7-10, and then, inputted into a center detector 11 and an angle of rotation detector 15. The detector 11 detects a voltage which corresponds to the error angle  of the center point E of the image of a target object B from the center point of the photosensitive plane A from points C and D where the image B changes, and the voltage is amplified 12  and 13. Then, a turntable 14 is rotated by horizontal angle alpha and a vertical angle beta, and the  center point E of the image B is brought to a position which coincides with a n optical axis A.  The detector 15 detects an angle theta formed by a line CD with the horizontal scanning line,  and finds the angle of rotation from the angle theta and controls each control wings 21-23 of an  induced flying body through control wing controllers 18-20. Thus horizontal and vertical advancing directions and inclined angles of control wings are controlled.

Title: Diversity receiver in broad-band digital radio communication
Inventor: SHIKI HARUO
IPC: H04L1/02
Filed: 1980-07-07
Abstract: PURPOSE:To make the detection of propagation distortion easy, by applying the receiver to a space diversity receiving system of a multivalue digital microwave communication system with good transmission efficiency. CONSTITUTION:Two signals having some frequency shifts are synthesized at a synthesis circuit 5. An intermediate frequency signal 7 zeroes the absolute delay time difference in existing between two signal transmission lines with an insulation delay time differential equalizer 10. Thus, even if a fading in 0dB-40dB is produced, the two signals on intermediate frequency output signals 11a-11b have almost the same level and phase. Next, although the output signals are subjected to propagation distortion when the selective fading is produced, an IF synthesizing device is controlled so that smaller propagation distortion can be selected without hit.

Title: Paper sheet carrying system
Inventor: WATANABE KIYOSHI
IPC: B65H5/06
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To easily and surely eliminate twists occurring in bent paper sheet portions by rotating a downstream side roll pair so as to temporarily eliminate a bent condition and rotating an upstream side roll pair at a high speed so as to recover the bent condition. SOLUTION: A document paper sheet P is pulled in by the rotation of a carrier roll 20 and carried such that the tip part of the paper sheet is butted on the nip part of a resist roll 30. In this case, the resist roll 30 is not rotated. The carrier roll 20 is reduced for its speed after the passage of a specified time and stopped. Thus, the document paper sheet P is bent in a space formed by carry path forming members 40 and 41. Subsequently, only the rotation of the resist roll 30 is started, and the document paper sheet P is sent out from its tip side. In this case, since the carrier roll 20 is in a stopped condition, the document paper sheet P is released from its bent condition. Then, by the releasing of this bent condition, a twist in the bent portion is also released.

Title: Ionic flow electrostatic recording head
Inventor: SHIGA NAOHITO
IPC: B41J2/415
Filed: 1992-04-13
Abstract: PURPOSE:To make a dielectric layer not liable to deteriorate even in usage at high temperature for a long period of time, and to make it available for forming highly minute images comparable to those made by using mica by a method wherein the dielectric layer for the title device is formed by applying heating and hardening to dielectric paste made up by using soluble glass or polyphosphagen as a binder. CONSTITUTION:In preparing an ionic flow electrostatic recording head 1, dielectric paste is made first by kneading soluble glass in JIS No.4, titanium oxide powder and barium titanate powder in weight ratio of 1:1:1.5, and furthermore by mixing active clay B-1 or the like in 100 wt.pts. to the soluble glass, and then a ceramic dielectric layer 4 is formed by applying the dielectric paste to spaces between patterns of a first electrode 3 over an insulating substrate 2 and to the electrode 3, and by applying heating and hardeneing thereto. Therefore, the dielectric layer 4 of the head becomes highly resistive against heat while being low in thermal expansivity, and hardly liable to deteriorate by thermal oxidation while being capable of keeping initial electric characteristic for a long period of time. Furthermore, since the surface of the layer 4 is at high temperature and being slow in temperature rise, leveling becomes easy while smoothness can be ensured for betterment of adhesiveness, and thereby highly minute images comparable to those made by using mica can be formed.
