Title: High brightness straight pipe fluorescent lamp device and high brightness reflection plate thereof, and clip for fixing high brightness reflection plate
Inventor: TAZAWA KAZUYOSHI
IPC: F21V7/22
Filed: 1990-06-04
Abstract: PURPOSE:To obtain a homogeneous reflecting characteristic, to reduce the weight, to facilitate the assembly, and to set the curving of a reflecting surface as desired by bringing a central line in the longitudinal direction of a high brightness reflecting plate into line almost contact with a bulb body of a fluorescent lamp, by placing both of rod-shaped end materials in the reverse side of the bulb body with each other, and by fixing and supporting the end materials with a pair of supporting pieces of a clip. CONSTITUTION:A central line in the longitudinal direction of a high brightness reflecting plate 1 is almost brought into line contact with the upper surface of a pipe body 5 of a fluorescent lamp provided almost horizontally, and both of rod-shaped end materials 2 are situated in the reverse side of the pipe body 5 with each other. A reflecting surface curved homogeneously as in an almost parabolic face with the pipe axis of the pipe body 5 of the fluorescent lamp as a center, by means of the interaction between the plane stability of a high reflector painted heat resistant resinous film 11 that forms the reflecting plate 1, and the tare of the rod-shaped end materials 2 fixed to the both ends in the longitudinal direction of the plate. The rod-shaped end material 2 of the high brightness reflecting plate 1 is received by any pairs of the supporting pieces formed on a clip 4 which is held in the outer periphery at least at two points of the pipe body 5 of the fluorescent lamp, and is loosely fixed and supported. The assembly is thus facilitated, and the degree of curving is selected as required, while no distortion of the reflecting surface is generated, and decorative effect is thus improved.

Title: Running control structure for work vehicle
Inventor: OCHI TATSUJI
IPC: A01D69/00
Filed: 1990-06-02
Abstract: PURPOSE:To improve the safety at reversing time while suppressing decrease of work efficiency by providing a constitution which switches between a condition that automatic deceleration is performed at a reversing time and a condition that the automatic deceleration is not performed at the reversing time. CONSTITUTION:A control means 17 is actuated to deceleration-operate a subspeed change mechanism 6 with a work vehicle left as reversed at a low speed in a relatively narrow work spot and a work spot with many obstacles. When the vehicle is thus reversed at a low speed, the situation of collision or the like against the obstacle can be avoided by performing steering operation without a delay at reversing time. Reversely in a work spot relatively wide with no obstacle, it is only required to perform no automatic deceleration by the control means 17 at reversing time by actuating a release means (second speed change lever) 23. In this way, work efficiency is prevented from deteriorating by performing quick advancing and reversing.

Filed: 1986-06-23
Abstract: PURPOSE:To form structure having no overhang section in order to prevent the lowering of breakdown strength due to the overhang section by processing a lower electrode for a stacked capacitor through oxidation by the self- alignment of a dielectric film. CONSTITUTION:The form of the end section of an silicon nitride film 10 as a dielectric film takes a parallel or slightly pushed-up wind shape because lower polycrystalline silicon 9 is oxidized by self-alignment using the silicon nitride film 10 as the dielectric film as a mask and polycrystalline silicon is converted into an oxide film 12 while being cubically expanded in the forms of the end sections of a lower electrode and the dielectric film. Consequently, the lower electrode 9 and an upper electrode 13 are not short-circuited, and the dielectric film is not shaped irregularly and no stress is applied. The lowering of capacitor breakdown strength resulting from an overhang section which has been at issue is improved, and yield and reliability are also enhanced.
