Title: Flash device
Inventor: YOSHIDA MASAAKI
IPC: G03B7/16
Filed: 1983-01-31
Abstract: PURPOSE:To execute a correct bounce photographing by shifting a light emitting part to a bounce position, and releasing an irradiation angle control operation based on a focal distance information by an irradiation angle changing means. CONSTITUTION:In case of a regular photographing state, the photographing direction of a camera and the irradiating direction of a light emitting part 2 coincide with each other. In this position, the light emitting part 2 depresses a push-button 6 and holds electric conductive cut pieces 8, 9 of an on-off switch 7 in an off-state. Also, as for an irradiation angle changeing means 14, a light emitting irradiation angle is controlled by a photographic lens focal distance information from a camera side. In case when a bounce photographing is executed, the light emitting part 2 is turned together with a turning part 3 by a photographer, and the irradiating direction is changed. In this case, the light emitting part 2 releases the depression of the push-button 6 and holds the electric conductive cut pieces 8, 9 of the on-off switch 7 in an on-state, therefore, the irradiation angle changing means 14 is controlled to a prescribed light emitting irradiation angle without being influenced by the photographic lens focal distance information from the camera side.

IPC: B22D11/106
Filed: 1991-02-06
Abstract: PURPOSE:To cast a cast billet having no blow hole by reducing the pressure of a gap part between an upstream side mold and a downstream side mold and casting, and in the casting by using horizontal continuous casting device connected with plural water cooling molds along the drawing direction of the cast billet. CONSTITUTION:This device is a horizontal continuous casting device, where a tundish and the molds are communicated with each other through a nozzle 13 and plural water cooling molds are connected along the drawing direction of cast billet. A silicone rubber-made O-ring 31 is inserted between the frame 17 of the upstream side mold 19 and the downstream side mold 21 so as to surround the cast billet C. The pressure is reduced by a gap (g) between the upstream side mold and the downstream side mold to execute the casting. By this method, as the pressure at the inside of the O-ring is reduced, the generation of the casting defect in the cast billet, such as blow hole, caused by air intruding inside of O-ring into the gap between the inner peripheral face of the mold and a solidified shell, is suppressed.

Title: Method for controlling travel of self-traveling working vehicle
Inventor: SOGAWA TAKAYUKI
IPC: G05D1/02
Filed: 1994-02-09
Abstract: PURPOSE:To improve the control of the travel of a self-travel working vehicle by enlarging a detection range, when a boundary is detected from an imaged picture image for controlling the travel of the vehicle along the boundary between a worked target range and a non-worked target range. CONSTITUTION:A picture image is imaged on the operation of a left stroboscope and subsequently subjected to a two-dimensional movement average treatment. Similarly, a picture image is imaged on the operation of a right stroboscope and subsequently subjected to a two-dimensional movement average treatment. The difference of brightness for each corresponding picture element between the respective average-treated picture images is computed to obtain a brightness difference picture image. The variation in the brightness of the brightness difference picture image in the horizontal axial direction is computed to obtain a brightness differential value picture image. Picture elements exceeding a slice level are extracted to produce a binary-coded picture image. The binary-coded picture image is subjected to a Hough transformation to compute a straight line for approximating a working boundary. Thereby, the variation in the brightness of the boundary in the brightness difference picture image is enlarged. The boundary can not only be examined up to a relatively far place, but also the working boundary can surely be detected without relating to day and night.

Patent JP-H02196462-A (JP)
Title: Semiconductor device
Inventor: ARAI HAJIME
IPC: H01L21/8247
Filed: 1989-01-24
Abstract: PURPOSE:To obtain a semiconductor device having a structure which is difficult to make the scattering arise in characteristics by mounting the dummy gate of a memory transistor which does not function actually at the outer peripheral part of gates of a memory transistor which functions actually so that its dummy gate is adjacent to a pattern at an endmost part of the foregoing gates. CONSTITUTION:In an EPROM, the dummy gate 8 of a memory transistor which does not function actually is mounted on an outer peripheral part of gates 3 of the memory transistor which functions actually in such a manner that its dummy gate is adjacent to an endmost part of the foregoing gates 3. For example, simultaneously with the formation of control gates 3 having memory cells which function actually as the EPROM, the dummy gate 8 which does not function actually but has a similar cross section structure is formed. The scattering of gate lengths L 1-L 5 of the control gates 3 which function actually is thus suppressed to a small extent. Consequently, this approach makes the scattering of characteristics of the memory transistor smaller only by taking a minimum space.
