Title: Tape guide device
Inventor: KONDO YUJI
IPC: G11B15/60
Filed: 1988-12-27
Abstract: PURPOSE:To attain highly accurate tape attitude by making a tape attitude regulation pole in contact on the inside of a tape so as to regulate the tilt in the broadwise direction. CONSTITUTION:The tape reaches a winding reel 112 from a supply reel 113 via a pin P3, a tension pole 33, a guide post 24a, a tilt post 24b, a rotary cylinder 30, a tilt post 23b, a guide post 23a, an audio and control head 32, a tape guide pole 31, a capstan shaft 20, an attitude regulation pole 40 and pins P1, P2. Even with the pin P3 having a play or tilt, since a pole 33 stood upright with high accuracy exists, the attitude of the tape is made stable. On the other hand, since the pole 40 is placed close to a tape eject part at the pins P1, P2, even with a play or a tilt in the pins P1, P2, the stable attitude of the tape is kept by the pole 40. The pole 40 has large diameter parts 40a, 40b at both ends while clipping a small diameter part to regulate the deviation of the tape in the broadwise direction of the tape. Thus, the tape attitude is kept with high accuracy.

Abstract: PROBLEM TO BE SOLVED: To increase a quantity of light to be emitted outside of a light guide plate separated from a light source by continuously forming an elliptical base having a protrusion formed in such a manner as to have a first dimension along a normal of an incident face greater than a second dimension along a widthwise direction of a light guide member and tilted faces extending with an angle tilted from the base, and forming a top parallel to the base.

Title: Method for manufacturing semiconductor device
Inventor: KURODA HIDEAKI
IPC: H01L21/336
Filed: 1992-11-17
Abstract: PURPOSE:To manufacture a semiconductor device with a small junction-leakage current and a large current-driving capability. CONSTITUTION:In the state wherein a tungsten polyside film 17 of the gate electrode of a semiconductor device is covered with an SiO2 film, an impurity is injected into a polycrystalline Si film 45, and the impurity is diffused to an Si substrate 11 to form diffusion layers 26, 32. Thereafter, the polycrystalline Si film 45 is covered with a resist 46 to remove the SiO2 film, and then, impurity ions are implanted into the tungsten polyside film 17. Since a formation of the diffusion layers 26, 32 and the introduction of the impurity into the gate electrode are performed separately from each other, the condition of the heat treatment of the introduced impurity can be set independently of others. Therefore, the diffusion layers 26, 32 having favorable junction characteristics can be formed, and the lowering of the concentration of the impurity of the gate electrode is prevented, and further, the decrease of the gate capacity of the semiconductor device and the increase of its threshold voltage can be prevented.

Title: Field-effect transistor
IPC: H01L29/778
Filed: 1989-12-20
Abstract: PURPOSE:To contrive a reduction in a source resistance by a method wherein a thin film, which consists of a material having an electron affinity higher than that of a material constituting a cap layer, is inserted into the interface between the cap layer and a carrier feeding layer as the cap layer. CONSTITUTION:An electron storage layer is formed in the vicinity of the interface of a cap layer 6 with a carrier feeding layer 4. When the discontinuous amount of a conduction band in the interface between the layers 6 and 4 is increased, charges stored in this electron storage layer in the interface of the layer 6 are increased and the sheet-resistivity of the cap layer is reduced. This can be realized by providing a second semiconductor layer 5a, which consists of a material having a large electron affinity, in the vicinity of the interface of the layer 6 with the layer 4. Thereby, the sheet resistivity of the cap layer can easily be reduced.
