Abstract: PURPOSE:To obtain a supporting roller which can be manufactured by mass production and having excellent load-proof and anti-wear characteristics by a method wherein a uniform mixture of a specified amount of polyphenylene sulfide resin, filler, anti-wear improver and hardness adjusting agent integrally injection molded. CONSTITUTION:A uniform mixture of 40 to 70% by volume of polyphenylene sulfide resin, 15 to 30% by volume of filler agent, 5 to 15% by volume of anti- wearing improving agent and 5 to 15% by volume of hardness adjusting agent is integrally injection molded. As the filler agent, non-organic filler such as barium sulfate, simple substance or mixture of organic filler agent such as Nomex fiber or the like is used. As the anti-wearing improving agent, material having a superior anti-wearing characteristic and having a low heat loss caused by a high frequency such as tetrafluoroethylene, graphite or the like is used. As a hardness adjusting material, olefin resin having a low surface hardness such as an ultra high molecular polyethylene and a high density polyethylene or the like is used. A product produced in this way becomes a supporting roller having a high rigidity, low heat loss caused by a high frequency wave and a high strength in response to each of its raw materials.

IPC: B65D85/50
Filed: 1995-09-04
Abstract: PURPOSE: To enable surely tearing apart the packaging film, in unsealing a package, along an unsealing line, along which the film is expected and designed to be torn, by forming a cutting line consisting of a variation of performations for tearing for the unsealing in the packaging film. CONSTITUTION: A cutting line 2 in the form of a variation of perforations is designed to have a film torn in a preliminarily set pattern. For this cutting line a multiplicity of incisions are formed in the packaging film in the form of a variation of performations which is a broken line designed, in the unsealing, to put right the tearing direction from diversion from one incised end by the incision next thereto. In the case where this cutting line 2 is formed in the package for a product such as a stick of sausage or cheese 7, it becomes easy to strip the product of the covering completely through exposure of a top portion followed by removal of the spliced back 8 in the shape of tape.  In this instance by so arranging the incisions 2 as to have the film torn in a curve at point, as shown in diagram, the tearing can easily be turned in direction at the points from a horizontal tear to a vertical one reaching the bottom.

Title: Synchronizing signal reproducing device
Inventor: OHASHI SHINICHI
IPC: H04N5/06
Filed: 1985-10-14
Abstract: PURPOSE:To prevent the malfunction due to noise by deciding the regularity of the external synchronizing signal, when the regularity exists, deciding that a correct external synchronizing signal is reaching and fetching this. CONSTITUTION:To a conventional circuit, a frequency deciding circuit 7 to decide the frequency, in which the arriving synchronizing signal enters into a window W1, is added. A frequency deciding signal 7 investigates and compares the frequency in which an arriving synchronizing signal E enters into the window W1 outputted from a window output generating circuit 6 and the frequency in which the signal does not enter, when the former is many, the E is acknowledged as the correct synchronizing signal, (M1 output generation), by an AND circuit A1, it is prevented that a counter 5 is reset by the E and the counter 5 is reset by a self-excitation trigger I. For example, to AND circuits A3 and A4, the inverting output by the window W1 and an inverter N1 are inputted together with an external synchronizing signal E. When the external synchronizing signal E exists in the window W1, the output appears at the output side of the AND circuit A3 and when the E exists at the outside of the window W1, the output appears at the output side of an AND circuit A4.

Title: Tri-state circuit
Inventor: YAMAGUCHI TAKESHI
IPC: H03K19/0185
Filed: 1986-09-24
Abstract: PURPOSE:To obtain a tri-state circuit which is reduced in occupation area by decreasing the number of MOS transistors. CONSTITUTION:when an OE signal is at high level, a Q3P is off and the source side of a Q2 P rises to high level; and a Q3N turns off and the source side of a Q1N falls to low level. When a DATA signal is held at low level, the Q1P and Q2P turn on and the Q1N and Q2N turn off, so an output Y falls to low level. Further, when the DATA signal is raised to high level, the Q1P and Q2P turn off and the Q1N and Q2N turn on, so the output Y rises to high level. When the OE signal is held at low level, the Q3P and Q3N both turn on. The gate potential of a Q4P is high in level and the gate potential of a Q4N is low; and the both turn off, so the output Y has high impedance.

Title: Melamine resin varnish and improvement of wood therewith
Inventor: IDE ISAMU
IPC: C09D161/20
Filed: 1992-08-26
Abstract: PURPOSE:To obtain a melamine resin varnish which has neither a risk of emitting a malodor when the melamine resin is cured nor causes crystals to be precipitated to thereby cause insufficient impregnation when wood is impregnated therewith. CONSTITUTION:Melamine is reacted with aldehyde and then with an alcohol to obtain a melamine resin varnish of a degree of etherification of the methylol groups with the alcohol of 25% of above. This varnish is infiltrated into wood and cured. Even when the etherified methylol groups are severed from the melamine resin during curing, they are not released in the form of form-aldehyde. This varnish is used after the content of the free alcohol is decreased to below 10wt.% in order to prevent crystals from being precipitated due to a concentration change caused by the evaporation of a lowboiling alcohol even when the system is evacuated in the impregnation of wood therewith.

Title: Lead frame, manufacture of its outer plating and manufacture of semiconductor device
Inventor: OGAWA KENTA
IPC: C25D5/50
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To obtain a PPF corresponding to an environmental problem at a low cost by using Ag for interior-finish plating and Sn-Ag for outer plating. SOLUTION: Interior-finish metal in thickness of 1-10 μm is formed in an interior-finishing region 2 containing an island 11 and at lest the front end sections of inner leads 12 by single-metal Ag plating. Outer plating having an Ag composition of 0-4% and thickness of 4-20 μm is formed in an outer region 1 comprising outer leads 13 and parts of the inner leads 12 by alloy Sn-Ag plating, thus completing a PPF. When outer plating having the Ag composition of 3.5% and thickness of approximately 8 μm is formed at that time, the coating properties and assembling properties of plating can be improved. Thus, since the alternate metal of Pb is used for an alloy for outer plating, the lead frame can correspond to an environmental problem at a low cost, and can be manufactured at the low cost. Accordingly, control in the post- process for manufacturing an IC is facilitated, and a production time can be shortened.
