Title: Lens barrel
Inventor: YABUKI TAKANOBU
IPC: G02B7/04
Filed: 1990-03-09
Abstract: PURPOSE:To reduce noise generated due to the resonance of a stop device by interposing an elastic member between the lower end surface of a main body and the upper end surface of a meter part. CONSTITUTION:When a motor 15 rotates, rotation is transmitted from a driving gear 15a to a focus gear 14a and a lens barrel rotation part 14 rotates. At this time, the lower end part of the stop device 12 where the meter part 12a is fixed is free, so it resonates greatly, but the elastic member 19 is interposed between the lower end of the main body 11 and the upper end of the meter part 12a. The resonance can, therefore, be absorbed by the elastic member 19. Consequently, the noise generated due to the resonance of the stop device 12 can be suppressed.

Filed: 1990-03-09
Abstract: PURPOSE:To improve labor saving and safety of an inspecting person in a man conveyer provided with a moving footboard by providing a portable type operation board for remote-controlling the traveling speed of the footboard at the time of inspection. CONSTITUTION:A switch box 7 for inspecting operation which serves as an operation board is connected to a controller 5 through a cable 6 provided with a receptacle. In the switch box 7, a start switch 8, a forward switch 9 and a backward switch 10 of push-button type and a change-over switch 11 of dial type are disposed. When the start switch 8 is pressed, inspecting operation is available, and when it is released, the operation is stopped. At the time of inspection, an inspecting person turns the change-over switch 11 to set it to any memory of 'low', 'medium' and 'high'. For turning on the start switch 8 and advancing the footboard 3, the forward switch 9 is turned on, and for retracting it, the backward switch 10 is turned on. It is thus possible to move the footboard 3 at a desired speed and in a desired direction.

Title: Production of decorative ceramic
IPC: C04B41/52
Filed: 1992-03-16
Abstract: PURPOSE:To form a relief-like glaze layer having an optionally regulated thickness on the surface of a ceramic. CONSTITUTION:The surface of a substrate which is a ceramic is partially coated with a water absorption rate modifier to form a part having a different water absorption rate in glazing. The surface of the substrate is then glazed to form a glaze layer of an uneven shape, which is then burned. Thereby, water in the glaze to be applied is absorbed in the substrate and the glaze readily sticks in a part uncoated with the water absorption rate modifier. In contrast to this, since the water in the glaze to be applied is hardly absorbed, the glaze hardly sticks and the thickness is reduced in the part coated with the water absorption rate modifier. As a result, an uneven glaze layer is formed.

Title: Cooling device for linear accelerator tube
Inventor: SUWADA TAKESHI
IPC: F25D17/02
Filed: 1990-03-09
Abstract: PURPOSE:To cool a nose cone part effectively by providing a passage of cooling medium along the circumference of a cylinder outer circumferential wall surface of a linear accelerator tube forming a hollow part. CONSTITUTION:Cooling medium is supplied from an entrance 31 to flow through a passage 3 along the circumference of a cylinder outer circumferential wall surface of a linear accelerator tube 1 to get out of an exit 32. The passage 3 has a groove protruding from the wall surface to the inner diameter of the accelerator tube, and a partition plate 4 separates the inflow side from the outflow side. For cooling medium in its flowing process, heat is radiated from the wall of a hollow 2, so by controlling the flow of cooling medium, the accelerator tube 1 can be cooled to be kept at a constant temperature. The groove protruding inside the tube 1 increases a heat radiation surface, so it absorbs radiated heat effectively. In this constitution, a sufficient cooling effect can be obtained even on an input of high output mu waves.

Abstract: PURPOSE:To make the device small and to easily realize a large scale neuron circuit network by connecting plural sensitivity variable light receiving elements to a gate terminal of a thyristor switched from the OFF state into the ON state when a gate current increases and reaches a predetermined value. CONSTITUTION:A variable sensitivity light receiving element 21 outputs a current Ii in response to a magnitude Xi of an input optical signal 1 and a photosensitivity (conversion efficiency). The conversion efficiency is increased as an inter-terminal voltage of the variable sensitivity light receiving element 21 increases. Each variable sensitivity light receiving element 21 is connected to a gate terminal 27 provided on a P-channel semiconductor layer 24 of a thyristor 23. The sum of currents Ii outputted from each variable sensitivity light receiving element 21 is inputted to the gate terminal 27 as a gate current I. When the gate current I is increased more than a threshold current, the thyristor 23 is turned on and a large current flows from an anode 26 to a cathode 28. As a result, a large voltage signal is outputted from an output terminal 32 of an output section 30.
