Title: Ferroelectric memory cell
Inventor: MOTOYOSHI MAKOTO
IPC: H01L27/105
Filed: 1991-02-21
Abstract: PURPOSE:To obtain a ferroelectric memory cell with relaxed internal stress of the ferroelectric body, improved magnet-keeping characteristic, and reduced generation of noise, etc., by surrounding a side surface of the ferroelectric body with resin. CONSTITUTION:A polyimide layer 10 is formed within a contact hole 20 and then a resist film 11 is formed selectively so that both sides of the polyimide layer 10 may be covered equally. After that, the polyimide layer 10 outside a region of the resist film 11 is eliminated by etching and a contact hole 21 is formed. Then, PZT is formed as a ferroelectric body on an entire surface of a silicon substrate 1 by the sputter method and a PZT film 12 is formed. Then, a Pt film layer 13 is formed on an entire surface of the PZT film 12 by the sputter method. Then, the resist film 11, the PZT film 12, and the Pt film 13 are simultaneously subjected to soft on and the PZT film 12 and the Pt film 13 are left only within the contact hole 21, thus enabling a side surface of the PZT film 12 and the Pt film 13 to be surrounded by the polyimide layer 10.

Title: Semiconductor laser optical device
Inventor: ARAI NOBORU
IPC: G02B7/00
Filed: 1986-02-10
Abstract: PURPOSE:To facilitate the relative positioning of a semiconductor laser and an optical element such as a lens by providing a marking member obtained by forming a pattern for position adjustment of a phosphor which emits visible light in response to a light beam. CONSTITUTION:The pattern 48 for position adjustment is formed oppositely to the position of a lens 5 where the light beam 1 should be incident, and the phosphor is applied concentrically and formed on a lens cap 7 as one example. The outermost periphery of the pattern 8 for position adjustment is almost in the same shape with the incident light beam 1. When the light beam 1 is made incident on a position shown by an an alternate long and short dash line, only hatched parts emit light. At this time, the phosphor at the outer peripheral part does not emit visible light circularly and left-side parts are off, so it is found that the position where the light beam 1 is made incident is not a correct position. For the purpose, a support base 6 which supports the lens 5 is moved to the right to position the lens 5 so that the light beam is made incident on the specific position.

Title: Vapor phase epitaxy system
Inventor: YOKOYAMA MITSUNORI
IPC: H01L21/205
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To prevent vibration of pinions to prevent chipping of the teeth of gears and to make the film thickness, etc., of the thin film grow uniformly by forming the internal gear and pinions 5 for rotating substrate holders of helical gears and constituting these gears in such a manner that the thrust in the axial direction generated in the pinions accompanying their rotation faces downward. SOLUTION: The internal gear 2 is horizontally fixed to a reaction vessel. The pinions 5 are freely rotatably fixed to a rotary plate 4 and are supported at their intermediate parts to the rotary plate 4 via thrust bearings. The substrate holders 7 are freely attachably and detachably mounted at the pinions 5. The internal gear 2 and the pinions 5 are the helical gears and are intermeshed with each other. The helix angle of the helical gears is preferably 3 to 30 deg.. As the teeth of the helical gears are formed helical, the intermeshing is smooth and since there are no backlashes, the gears vibrate less. The helical gears have the large number of the teeth which simultaneously intermesh each other and, therefore, the helical gears are advantageous in terms of strength. Since the axial direction thrust of the pinions 5 is always downward, there is no need for intricate bearings.

IPC: G06T3/40
Filed: 1988-02-10
Abstract: PURPOSE:To arbitrarily expand and reduce a picture at high speed simultaneously in longitudinal and transverse directions by converting longitudinal and transverse sizes with the use of a pattern converting ROM. CONSTITUTION:An original picture is divided at every matrix at mXn dot, and by converting it into the matrix at iXj dot, it can be expanded or reduced i/m-fold and j/n-fold in the longitudinal and transverse directions respectively. For example, a pattern at 3X3 read from a first RAM 1 is converted through a serial/parallel converter 6 into the pattern at 4X4 by a pattern converter ROM 7 based on a prescribed converting basic rule. Thus, the picture can be expanded and reduced at high speed at longitudinally and transversely arbitrary magnification.

Abstract: PURPOSE:To facilitate assembling, eliminate spherical element missing, and improve reliability by forming a spherical element housing part in a metal holder which houses the spherical element of a diameter (d) so that the internal diameter may be held at D>d, and the internal diameter of an opening end may be held at Di<d and Di<D, and the spherical element in a not-constrained condition. CONSTITUTION:A spherical element housing part 20 is provided at the deep part of a metal holder 10, and the internal diameter D is made larger than the diameter (d) of a steel spherical element 11b. The ring-shaped projection 21 of the opening edge of the spherical element housing part 20 is formed at the internal diameter Di so that Di<d and Di<D may be satisfied. When a steel sphere 11b is installed inside the spherical element housing part 20, it is semi-pressure-inserted because the ring- shaped projection 21 is provided at the opening edge, but the steel spherical element 11b is held in a non-constrained condition after installation. When a radial bearing 9c is installed, the opening edge is made to open easily from a cut part 22, and the radial bearing 9c is held by elastic force. It is thus possible to reduce assembling manpower, and eliminate the possibility of missing the steel spherical element after assembling, thus improving reliability and quality.

Title: Automatic tuning receiver
Inventor: MIYOSHI KAZUHIDE
IPC: H03J7/18
Filed: 1992-02-14
Abstract: PURPOSE:To provide an automatic tuning receiver free from the trouble of tuning operation by controlling continuation/stop of scanning by a threshold for stop stored in a ROM at the time of the occurrence of abnormality in an E<2>PROM where a threshold for frequency scanning stop is stored. CONSTITUTION:The threshold for backup, for example, data for check as 8-bit data is preliminarily written in a ROM 172. When it is regarded that error occurs in an E<2>PROM 173, the threshold for backup is used to stop the tuning scanning. The tuning control routine executed by a CPU 171 reads out data for check from the ROM 172 and the E<2>PROM 173 and discriminates whether they coincide with each other or not. If they do not coincide with each other, the threshold for backup stored in the ROM 172 is used and is compared with a field intensity signal. The scanning frequency is incremented when the field intensity signal is smaller, and scanning is stopped or terminated when it is larger.
