Title: Cassette type video tape recorder
Inventor: NOYAMA TAKASHI
IPC: G11B15/087
Filed: 1984-11-27
Abstract: PURPOSE:To prevent damages to a magnetic tape by allowing the magnetic tape into press contact with a fixed magnetic head at the fast feeding and rewding mode and winding the magnetic tape to a rotary head drum at a recording and reproduction mode. CONSTITUTION:The magnetic tape 7 is drawn from a cassette 3 by a required minimum value at the fast feed rewinding mode, and a tape loading post or the like is moved from a position 28b to a position 28c at the recording and reproducing mode and the post 28a is at a position 17 for abutting onto the magnetic tape 7 while the magnetic tape 7 is wound on the rotary head drum 2. Since the winding angle C of the magnetic tape 7 to the tape loading post 28a to allow the magnetic tape 7 into press contact with an A/C head 17a at the fast feeding and rewinding mode is small, the running load of the magnetic tape 7 is small and the winding reel torque is small. since the drawing amount of the magnetic tape 7 is small by the tape loading post 28a, the magnetic tape 7 is hardly abutted onto the rotary head drum 2 to prevent the damages from the magnetic tape 7.

Title: Lead frame
Inventor: ITO YUJI
IPC: H01L23/50
Filed: 1989-09-26
Abstract: PURPOSE:To realize an excellent lead frame which does not cause a problem such as a burr and a slack and to supply a high valueadded product at a low cost by a method wherein a burr production direction is decided selectively at each constituent part of the lead frame and burr production directions are formed by combining two kinds on the surface and the rear. CONSTITUTION:A metal thin film 13 which has been fed by using a feeder 25 is pressed and shaped at a first press and shaping apparatus 23; stamping positions 20, 20' are stamped together with other parts. After that, the surface and the rear of the metal thin sheet 13 are inverted; the sheet is fed to a second press and shaping apparatus 24; stamping positions 21, 21' and 22 are stamped one after another together with other parts; after that, the sheet is removed by using a material-removing apparatus 27. Consequently, a direction of burrs produced in the stamping positions 21, 21', 22 becomes opposite to a direction of burrs produced in the stamping positions 20, 20'; a burr production in a part situated between a molding region 9 and a dam bar 6 is opposite to it. Thereby, a problematic point such as the burrs and slacks is eliminated, and a high-quality semiconductor device can be produced stably.

Abstract: PURPOSE:To obtain a transfer material having excellent recorded density and printing quality while maintaining high heat resistance and mechanical strength, by providing a low electric resistance layer and a high electric resistance layer on one side of a composite base comprising a heat-resistance protective layer on a high molecular weight material film, and providing a coloring material layer on the other side. CONSTITUTION:A composite base 3 comprising a heat-resistant protective layer 2 on at least one side of a high molecular weight material 1 is used, a low electric resistance layer 4 and a high electric resistance layer 5 are provided on one side of the composite base 3, and a coloring material layer 6 is provided on the other side of the base 3 to produce a transfer material. With the low electric resistance layer 4 provided between the composite base 3 and the high electric resistance layer 5, a high-temperature heat generation distribution is obtained beneath the base 3. The heat-resistant protective layer 2 prevents the heat resistance of the base from being deteriorated due to the heat generation beneath the base. Notwithstanding the presence of the nonconductive base 3 between the coloring material layer 6 and the resistance layers 4, 5, the heat generation distribution can be obtained beneath the base, resistor layers required as the resistance layers can be easily provided, and an ordinary thin high molecular weight material film 1 can be used as the base, so that excellent printing quality and high recording sensitivity can be obtained while maintaining a sharp distribution of heat generation and while preventing heat transfer efficiency from being considerably lowered.

IPC: H01L29/12
Filed: 1990-09-20
Abstract: PURPOSE:To make a resonance tunnel effect take place and permit this effect to be suitable for a superhigh speed IC by providing a recessed or protruding region at the 1st semiconductor layer of a hetero junction interface which makes up a semiconductor device and preparing a potential well or barrier toward two dimensional electrons which are accumulated at a second semiconductor layer in the vicinity of the interface. CONSTITUTION:An N-type AlGaAs layer 2 in which donor impurities are doped is laminated on an undoped GaAs layer 4 which has a gap narrower than the layer 2 and has a low energy at the lower end of a conduction band while making its layer hold a position in the direction of Z and hetero-junction is obtained. Further, having a width of W1 and a depth of D1 which run in the direction of Y, a recessed region 6 is provided in the layer 2. In this way, potential in a hetero junction interface is changed by the recessed region 6 and then discontinuous gaps caused by a lower end energy are produced at even a junction interface in the direction of X as well as at the junction interface in the direction of Z. This makes potential at the base of the recessed region 6 lower than those of junction interfaces in regions except the region 6 and permits electrons to produce a tunnel effect.
