Title: Thin film transistor array
Inventor: TANAKA HIDEO
IPC: H01L29/786
Filed: 1989-02-15
Abstract: PURPOSE:To prevent the manufacture yield and throughput from decreasing although a double-speed line sequential scan can be made by providing both gate and common electrodes on the same plane and forming a holding capacitor of the common electrode and the source electrode side of a thin film transistors (TFT). CONSTITUTION:A gate electrode group 14, the common electrode 15, and a drain electrode group 16 are provided. When an ON signal is applied to a gate electrode, only all of the TFT of a certain line turn on and a data signal inputted from the drain electrode group 14 is received only in the period and written in a picture element 11 and the holding capacitor 10. When the ON signal is ceased, the TFT of the Nth line turns off and the data signal is held until it turns on again. The ON signal is sent to the gate electrodes. When a scan is made by a method which sends the ON signal to every two gate electrodes, resolution and a flicker which are similar to those of a line sequential scan are obtained and the time of the application of the ON signal is made similar to that of an interlaced scan. Consequently, neither the manufacture yield nor the throughput decreases.

The mixed material is charged on the pallet of sintering machine in tilted way, so that the converter slag is placed mainly at the lower part of raw material-filled layer, and sintering is performed. This causes magnetite to increase in the sintered ore and to strengthen bind structure by slug resulting in enhanced resistance to reduction and powdering of lower layer of sintered ore.

Title: Paper feeding device for plate making machine of electrophotography
Inventor: HASHIMOTO KAZUYUKI
IPC: B65H1/26
Filed: 1983-03-08
Abstract: PURPOSE:To prevent collision of a paper feeding cassette or the tip end of sensitive paper against a paper feeding roller by a method wherein the paper feeding cassette is inserted smoothly into the receiving unit of the cassette by only effecting the inserting operation of the paper feeding cassette, in the paper feeding device of the titled apparatus. CONSTITUTION:When the paper feeding cassette 2, supplemented with sensitive paper 1, is inserted into the cassette receiving unit 3, the abutting part 22 of the paper feeding cassette 2 is abutted against the tongue 15A of an operating lever 15 when the sensitive paper 1 has arrived at the lower part of the paper feeding roller 4. Thereafter, when the paper feeding cassette 2 is inserted further, the operating lever 15 is moved to the other end of reciprocating stroke against a spring. According to the movement, a roller lifting lever 18 cooperates with the operating lever 15 and descends to a position, not bothering the descending of the paper feeding roller 4, while the paper feeding roller 4 is released from the restriction of the roller lifting lever 18 and descends onto the sensitive paper 1. Thus, the paper feeding roller 4 descends after the sensitive paper 1 has arrived at the lower part of the paper feeding roller 4, therefore, the roller 4 will never collide against the cassette 2, the tip end of the sensitive paper 1 or the like.

Title: Manufacture of thermosetting resin curved tube
Inventor: SHINADA MASAO
IPC: B29C33/04
Filed: 1986-02-21
Abstract: PURPOSE:To make it possible to mold a curved tube only by thermosetting resin, even if the shape of the curved tube is complicated to some degree by having many bends by a method wherein an elastic hollow body is used as a core so as to give molding pressure by uniformly and elastically deforming the core with the fluid forced in the hollow part of the core and to heat under the state just mentioned above. CONSTITUTION:Uncured fiber reinforced plastic (FRP)11 is wound round a core 10 consisting of an elastic hollow body made of hollow silicone rubber. Heating fluid is forced in the hollow part from the respective ends of the cores 10 and 12 in the direction indicated with the arrows so as to heat and cure the uncured FRP11. In this case, the heating fluid omnidirectionally and uniformly applies fluid pressure to the core 10. Thus, the core 10 urges the uncured FRP11 on the mold surface of a molding tool 15 and at the same time the heat of the heating fluid thermally cures the uncured FRP11. Next, a curved tube is removed from the molding tool and, in addition, the core 10 is pulled longitudinally. Because the core 10 is made of silicone rubber, the core 10 is easily released from the thermally set FRP11 and drawn off.

Abstract: PURPOSE:To minimize an irregularity of light value between heads with an optimum light-emitting value obtained, even when the head is replaced by installing a driver which drives a light-emitting element and a memory on the first substrate, and arranging a drive part on the second substrate. CONSTITUTION:A power supply on the substrate 4 side is connected to the anodes of LED chips 21-2n.
