Title: Ascent-descent loading device for short cylindrical member
Inventor: MINOU HIROAKI
IPC: B65G17/12
Filed: 1982-12-27
Abstract: PURPOSE:To rationalize operation processes by taking out stagnating wooden tubes of a vertical type bucket conveyor, which are scooped up individually from a hopper, at any level using an elevating feed conveyor equipped with a Venetian shutter, and thereby enabling to change the height of stacking in free. CONSTITUTION:Wooden tubes are scooped from a hopper 9 by a circular travelling bucket conveyor 10, and when a scooped tube has passed the turning point at the top, it shall be sunk under holding by a retainer plate 10a of the conveyor 10 and a retainer plate 16a of a Venetian shutter 16. When the tube has attained a tube passing window 16a provided in the retainer plate 16a, it rolls out by its own weight to move on a guide plate 22 and is transferred onto a conveyor 21. Because this conveyor 21 is driven with its transport belt by a motor 21a in a single direction at all times, the wooden tubes loaded are transferred to the accommodator side and cast in from the end part. According to this arrangement, loading of short cylindrical members does not require human labor, and can be carried out while a proper level is held by a simple device.

Title: Lighting optical system
Inventor: HIGASHIURA KAZUO
IPC: G06T1/00
Filed: 1990-08-31
Abstract: PURPOSE:To prevent the change of brightness and darkness of the uneven pattern as the change of the direction of a work by splitting an incident luminous flux into plural numbers with a reflection member, and radiating it on a surface to be picked up from many directions. CONSTITUTION:An illumination light radiated from a light source 1 is made incident on a reflection member 10-13, and the reflection member 12, 13 splits and reflects the incident luminous flux in a direction different to each other, and also in an oblique direction so that they are symmetrical to each other to the incident direction of the luminous flux. The split illumination light radiates on the surface 5a to be picked up of a split plurally and radiates on the surface to be picked up of the work. Thus, the brightness and darkness of the uneven pattern of the work does not change even when the direction of the work is diverse, and an illumination optical system, which can be mounted even when the mounting space is limited to a small range, can be obtained.

Title: Semiconductor laser
Inventor: AZUMA TOSHIO
IPC: H01S5/00
Filed: 1992-08-31
Abstract: PURPOSE:To make it possible to obtain a high output even under the effect of a spatial hole-burning penomenon by a method wherein the reflectance of an antireflection(AR) coat is optimized taking a matter that the density distribution of carriers in a semiconductor laser is ununiformized due to the spatial hole-burning phenomenon into consideration. CONSTITUTION:A low-reflectance film 30 is formed on the end surface on one side of the end surfaces of arc active layer 16, a high-reflectance film (an HR coat) 32 is formed on the other end surface and a resonator is constituted of these films. In this case, when the reflectance R0 of the AR coat 30 is shown by alpha1 L (Provided that, the alpha1 is the absorption factor of the layer 16 and the L is a resonator length on the layer 16.), the low reflectance R1 of the AR coat 30 is set within a range of R0/2<R1<2R0. Moreover, an electrode, through which a current is injected in the layer 16, is split into at least an electrode on the side of the film 32 and an electrode on the side of the film 30 and a current I1, which is injected through the electrode 34 on the side of the film 30, is made higher than a current I2, which is injected through the electrode 36 on the side of the film 32. Thereby sufficiently high output characteristics are obtained in consideration of the density distribution of carriers in the direction of the resonator.

Title: Medium defect detector for disc unit
Inventor: SHIRAI KUNIAKI
IPC: G01R33/12
Filed: 1984-11-02
Abstract: PURPOSE:To increase the defect detecting capacity of a medium, by providing a plurality of phase matching type oscillators (PLO) the same in the oscillation frequency but different in the time constant, a plurality of switches (SW) and a decoder circuit. CONSTITUTION:A defect detection reading signal of a disc medium on a signal line 1 is inputted into PLOs 41-44 the same in the oscillation frequency but different in the time constant to start the oscillation according each of time constants. An oscillator selection signal on signal lines initially selects a SW51 of the PLO41 with the shortest time constant. When the oscillation of the SW52 of the PLO42 with the time constant the shortest next to the preceding one is established, the oscillator selection signal is switched at the timing of zero- crossing the oscillation from the SW51 to the SW52. Thereafter, likewise, the switching of the signal is done sequentially to the PLO longer in the time constant and finally, the SW54 of the PLO44 with the longest time constant is selected to continue the oscillation with the SW54. Thus, the state to disable the continuation of processing can be avoided due to a decrease in the reading output due to a defect of a medium.
