Title: Resin composition for sealing semiconductor device
Inventor: FUJIEDA SHINETSU
IPC: C08L61/04
Filed: 1987-09-30
Abstract: PURPOSE:To obtain the title composition having excellent mold release and moldability without detriment to the inherent heat resistance and low coefficient of thermal expansion, etc., of a maleimide resin composition, by using a polyethylene wax as an internal mold release. CONSTITUTION:The title composition is prepared by adding a polyethylene wax (one which comprises polyethylene of an MW of 500-4,000 and has COOH groups as a polar group introduced by, e.g., modification by oxidation or modification with an acid) to a resin composition containing a maleimide resin (e.g., one comprising a maleimide resin and a novolac phenolic resin and/or an epoxy resin and an organophosphine compound). By using said internal mold release, it is possible to impart excellent mold release and moldability to the obtained composition without detriment to the excellent heat resistance and low coefficient of thermal expansion inherent in the maleimide resin itself.

Title: Production of semiconductor device
Inventor: AONO MITSUHIRO
IPC: H01L21/30
Filed: 1987-09-30
Abstract: PURPOSE:To completely remove the scum of a developing soln. and resist by adopting two-stages processing of cleaning by an aq. alcohol soln. and cleaning by pure water in a stage for rinsing the photoresist pattern applied on a semiconductor substrate and subjected to exposing and developing. CONSTITUTION:The photoresist 3 is applied on the semiconductor substrate 2 on which a film 1 such as silicon oxide film or polycrystalline silicon film is formed. The photoresist is subjected to soft baking at a prescribed temp. The photoresist 3 is then exposed by UV irradiation using a photomask 4 and is developed by the developing soln. The resist pattern is formed after this resist is subjected to the rinsing stage. The rinsing is executed by first injecting the aq. alcohol soln. from a nozzle 8 onto the substrate 2 while rotating the substrate, then by injecting the pure water from a nozzle 9 to clean the resist pattern with the pure water. The rotating speed of the substrate is increased after two stages of said cleaning and the substrate is subjected to spin drying. The resist pattern is thus formed without having the remaining developing soln. and the resist scum. The yield and reliability of the semiconductor device are, therefore, improved.

Inventor: MATSUURA TOSHIO
IPC: G06K9/34
Filed: 1983-12-29
Abstract: PURPOSE:To separate characters for one character's share from a manuscript character pattern by providing a means detecting specific line segment end point where a specific line segment contacts a character pattern and a character separating section separating the character pattern based on the line segment end point. CONSTITUTION:The range of a threshold value alpha is decided from a center line C of a lateral area of the character area, the range is scanned horizontally and the center position of the part clipped with black points is obtained as the specific line segment. The specific line segment is obtained from the upper and lower range respectively in this way and when plural specific line segments exist, the segment closer to the center line C is adopted. When the specific line segment from the upper range and that from the lower range are in contact with the character pattern, the character pattern is separated from the contact point closer to the center line C as shown in (D). Thus, the contacted manuscript character pattern is separated accurately with a comparatively simple means.

Title: Picture synthesis device
Inventor: SATO TAKASHI
IPC: H04N5/45
Filed: 1992-09-17
Abstract: PURPOSE:To provide the inexpensive picture synthesis device whose control is simple without need for a transparent frame memory by selecting display priority of plural picture data outputted from plural picture frame memories and controlling a picture output. CONSTITUTION:A selection section 1 has a changeover circuit and a setting section 2 decides display priority for each picture frame according to the setting set based on a control signal and implements control to set forcibly a least significant bit with less effect on visual observation.

Title: Clock control system for communication interface
Inventor: TAHIRA FUMIAKI
IPC: H04L29/10
Filed: 1990-09-19
Abstract: PURPOSE:To save labor for reconnecting a cable with connector before changing a mode by changing the mode by both a hardware and a software. CONSTITUTION:A control part 18 of a line terminal equipment (DTE) 11 is equipped with an RS232C interface. When executing synchronous communication, this RS232C interface has two timing control modes such as an ST1 mode to get transmission timing based on the own clock when being observed from the DTE (the equipment itself) and an ST2 mode to get transmission timing reversely based on the clock of a DCE (slave device). In this case, the ST1 mode and the ST2 mode can be switched by the software and selected by the hardware as well. Thus, it is not necessary to prepare the cable corresponding to each mode, and labor for reconnecting the cable is saved.

Title: Frp leaf spring equipment
Inventor: MISUMI ATSUSHI
IPC: F16F1/368
Filed: 1984-11-22
Abstract: PURPOSE:To reduce vibration and to enhance riding comfort in an FRP leaf spring equipment for a suspension part of a vehicle by forming the equipment in such a manner that the main board, which has an eye part at its both ends and which is wider only in its width than a sub-board, is placed on the sub- board. CONSTITUTION:Width L of a main board 2 is wider than width 1 of a sub-board 3 except for the part, in which a eye-part 5 is provided, thereby increasing rigidity of the main board 2. With this constitution, even with FRP material, a drop in lateral rigidity can be restricted. In addition, since the width of the eye-part need not to be changed, difficulty in fitting work can be avoided. Thus, riding comfort can be enhanced, while vibration of the vehicle can be reduced.

Title: Heat treatment
Inventor: ARIMI YUKIO
IPC: C23C8/22
Filed: 1990-09-17
Abstract: PURPOSE:To suppress the deformation of a steel member due to heat treatment while ensuring the fatigue strength by carburizing and carbonitriding the member and then carrying out hardening at a specified temp. CONSTITUTION:A steel member is carburized and carbonitrided by holding at the A1 point of the steel or below, e.g. at 650-730 deg.C in an atmosphere of carbonitriding gas and then hardening is carried out by quenching from the A1 point of the steel or below. Since nitrogen is allowed to enter into a solid soln. in the surface of the steel member by the carbonitriding, the structure of the steel is austenitized by heating to the A1 point or below and the austenite structure is converted into martensite by the subsequent quenching to attain hardening. The fatigue strength of the member is ensured and the deformation of the member due to heat treatment is hardly caused even by hardening because thermal stress produced is small owing to the low hardening temp. of the member.
