Title: Door stopper
Inventor: MARUYAMA TOMOHIKO
IPC: G07F9/10
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To make the opening degree of a door surely regulatable by disposing a turn regulating means which is located at the opening and closing path of a commodity storage room door and regulates the turning of the commodity storage room door to a prescribed open state by pressing the commodity storage room door based on the weight of the commodity storage room door. SOLUTION: A steel ball 2 is inserted into an opening 1C of a base 1, the ball 2 is held by a holder 3 and the base 1 is attached to the body of a vending machine with a vis 4. Also, a receiving metal fitting 5 is attached to the lower part of a commodity storage room door 24 with a vis. When the door 24 is turned with a door supporting part 1A as an axis, the head of the vis that attaches the fitting 5 is brought into contact with the ball 2 and when it is further turned, the head of the vis runs on the ball 2. As a result, the ball 2 is held by the plus groove of the vis head and the door 24 are fixed. When the door 24 is turned even more, the head of the vis runs over the ball 2 and the door 24 is prevented from being closed in such a manner that the head of the vis and the ball 2 interfere with each other.

Abstract: PURPOSE: To easily perform extrusion in prescribed dimension and shape, by installing a straightening block at the outlet side section in the die in such a way that the block rocks in accordance with meandering movement of shaped materials, when the shape of extrusion forming material, of an Al alloy is straightened.  
     CONSTITUTION: When a shaped material M suck as sash is formed by an extrusion of an Al alloy material with a die 1 composed of a baffleplate 2, a die 3, and a back die 4, a pocket 8 connected to an open hole 7, through which the shaped material M passes, is formed at the rear end of the back die 4, and a straightening block 9 is loosely inserted into the hole 7. Moreover, a bolt having a hexagonal socket head 11 is fixed to the end of a wire bar 10 passing through the straightening block 9, and the straightening block 9 is supported in such a way that the block rocks in radial directions. While material M makes meandering movements after coming out from the die 1 depending on the shape and the extrusion condition, almost all the shaped materials coming out from the die are finished within a range of tolerance without any requirement for correction, because the straightening block 9 also rocks in accordance with the meandering movement of shaped material M.

Title: Light emitting diode
Inventor: KAMATA NORIHIKO
IPC: H01L33/06
Filed: 1983-08-26
Abstract: PURPOSE:To obtain low distortional characteristics and broad band characteristics and, at the same time, to enable to contrive maintenance of a high efficiency by a method wherein dope electrons and dope carriers are constituted in such a manner that they are spatially isolated. CONSTITUTION:When the thickness of an active layer A is thinned off to the extent of quantum expansion of electrons, electrons can not move freely in the direction of layer thickness and energy is brought to show a quantized debunching level. Such a thin active layer is called a light emitting layer, and the light emitting layer or its arrangement is called a quantum well structure. Hence, when a high doping is performed on the barrier layer H only without performing a doping on dope atoms on the light emitting layer F, the dope carrier I supplied from the dope atoms D is accumulated on the layer F having the potential lower than the layer H, and the atoms D and the carrier I can be dispersed spatially. As a result, a high density doped carrier only is present on the light emitting layer, and an excellent linearity and a broad band can be obtained. On the other hand, as dope atoms are present on the barrier layer, no luminous efficiency is deteriorated.
