Title: Sheet and its production
Inventor: TACHIKAWA KOJI
IPC: B29C47/00
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a sheet having surface smoothness and sound insulation which is superior to those of a conventional sheet, less in the unevenness of thickness and suppressed in the number of the defects from which breaking of the sheet may start. SOLUTION: A sheet consisting of a thermoplastic resin composition prepared by melt-kneading 0.5-100 pts.wt. of a liquid crystal resin (B) into 100 pts.wt. of an olefin resin (A). In this sheet, the combination of the olefin resin (A) and the liquid crystal resin (B) has the following features: the ratio of the melt viscosities of the olefin resin (A) to the liquid crystal resin (B) [melt viscosity of (A)/melt viscosity of (B)] is 1.2-100, wherein the melt viscosities are determined with a shear rate of 1000/sec at the temperature corresponding to the resin temperature during the melt-kneading of (A) and (B); the liquid crystal resin (B) is a liquid crystal polyester comprising constituting units expressed by formulae (I), (II), (III) and (IV) (R1 is one or more groups selected from the groups shown by formula I;  R2 is one or more groups selected from the groups shown by the formula II; and X is H or a chlorine atom).

Title: Controller for master/slave manipulator
Inventor: ASAKURA MAKOTO
IPC: B25J3/00
Filed: 1990-10-09
Abstract: PURPOSE:To simplify the structure of a master slave manipulator and to improve its stability during operation by inputting a command value sent from a force control means and a detected value given by a master kinetic value detecting means for presuming the estimated kinetic value of the master manipulator, and providing a master kinetic value estimating means to input the estimated kinetic value into a position controlling means. CONSTITUTION:A detected value sent from a force controlling means 7 and a detected value given by a master kinetic value detecting means 21 are inputted into a master kinetic value estimating means 33. The master kinetic value estimating means 33 estimates the future kinetic value of a master manipulator 3 to send it to a position controlling means 9. The target position of a slave is made to have an advance to the master manipulator 3 by regarding the future kinetic value as the target value of a slave manipulator 5, but since the position of the slave manipulator 5 is behind the target position of the slave, the advance based on the estimated position of the master manipulator 3 is regulated to compensate the delay in following the phases of the manipulators.
Patent JP-H05109976-A (JP)
Title: Semiconductor device
Inventor: YODA TOSHIYUKI
IPC: H01L25/07
Filed: 1991-10-17
Abstract: PURPOSE:To prevent displacement of a semiconductor chip at the time of resin molding by connecting two semiconductor chips with rear faces closely adhering to each other to an outer lead by tape leads, attaching a first fixing member to a surface of one of the semiconductor chips and attaching a second fixing member to a surface of the other semiconductor chip. CONSTITUTION:Semiconductor chips 3A, 3B are connected to an outer lead 6a by tape leads 5A, 5B. A first fixing member 20A is fixed to a surface of the semiconductor chip 3A by adhesive 21 as well as a second fixing member 22A is fixed to a surface of the semiconductor chip 3B by the adhesive 21. Therefore, when this assembly is set in a metal mold and is subjected to resin molding, even if force is applied to the semiconductor chips 3A, 3B due to injection pressure of mold resin 7, the first fixing member 20A regulates a distance from an upper metal mold while the second fixing member 22A regulates a distance from a lower metal mold. Thus, a tape lead can be prevented from appearing on a package surface, thereby preventing electric snort-circuiting with outside at the time of packaging.

Title: Boring device for printed wiring board
Inventor: HATTORI OSAMU
IPC: H05K3/46
Filed: 1988-10-26
Abstract: PURPOSE:To realize control of a machining distance by detecting a change of a machining resistance upon a drill during machining. CONSTITUTION:For example, a substrate such as a multilayer wiring board is constituted by laminating a copper section and a resin section in layers. When boring such a substrate, these layers are machined alternately, and a thrush load on a drill 1 thereby changes. Variations in the thrust load are detected by a thrust meter 13 and picked up by a data analizer 14. By counting the frequency of the variations, it is possible to confirm which layer of the copper patterns is machined by the point of the drill. When a specified pattern layer is machined, the analyzer 14 feeds back a signal to a Z-axis direction servo-motor 9 to stop the feed of the drill 1. A blind hole to a specified pattern layer can be thereby formed accurately even for a multilayer board having irregularity in board thickness.

Hereupon, cranking or the like, where the intake amount of air increases, is detected, and the detection value of the crank angle is corrected to be calculated by forcedly performing the fuel cut. Consequently, a displaced degree of the crank angle can be high accurately detected.
