Title: Gallium phosphide light emitting device
Inventor: NISHIZAWA JIYUNICHI
IPC: H01L21/208
Filed: 1979-08-27
Abstract: PURPOSE:To easily obtain the LED having high green light emitting efficiency by employing a low doner density N type GaP region without adding nitrogen thereto. CONSTITUTION:A predetermined temperature difference is provided in a GaP-Ga solution, phosphorus pressure within optinum range is applied onto the solution, GaP stock material is dissolved in the solution retained at predetermined high temperature, and is epitaxially grown at the low temperature portion thereof. In this manner there can be obtained an N type GaP region having doner density of less than 1X10<16>cm<-3> without adding nitrogen thereto. The GaPLED forming an N type GaP region, a P type region having acceptor density implanted with sufficient amount of holes within the N type region, and a P-N junction incorporates very high light emitting efficiency. Since no nitrogen is added thereto, a light having visulally cleary peak wavelength of less than 5,600Angstrom  can be easily generated in high light emitting efficiency.

Title: Structure of combined compression coil spring
Inventor: SUZUKI SHIGERU
IPC: F16F3/04
Filed: 1982-06-28
Abstract: PURPOSE:To obtain a comparatively large ratio of the compressible length against the natural length in a compression coil spring as keeping a fixed spring constant. CONSTITUTION:The first, the second, and the third stage compression springs 21, 23, and 25 are all of the same spring constant, and piled up in series with the first and the second stage spring receivers 22 and 24 between.

Title: Method for hot extrusion
Inventor: TAKAHASHI TSUNETOSHI
IPC: B21C23/00
Filed: 1992-04-28
Abstract: PURPOSE:To reduce top and peak extrusion pressure and enlarge a range which can be extruded by optimizing the combination of a flowing in angle of material into a die, a hole diameter of the die, a tapered angle of the tip part of the material and the diameter of the billet. CONSTITUTION:The value of the taper angle beta of the tip part of the material the angle alpha, of the die is made <=0.75, the end face of the tip part of the material is cut by >=20mm to give a taper and the diameter(d) of the tip of the materil/the diameter D of the die hole is made <=2.5. In this way, the value of the top and peak extrusion pressure Pr/a stationary extrusion prssure Ps is reduced and a range which can be manufactured by hot extrusion can bw widened. For example, when the stationary rolling pressure Ps and the top and peak pressure Pr are compared with each other as SUS304 is used for the extrusion material, the stationary extrusion pressure Ps does not change but the top and peak extrusion pressure is reduced in a combination of alpha=90 deg. and beta=30 deg..

Title: Burned magnesia-chrome brick
Inventor: KAWAMOTO EIJI
IPC: C04B35/047
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To improve the wear resistance, namely hot strength, of a burned magnesia-chrome brick mainly used in an AOD oven by adding fine Al2 O3 powder having a specific average particle diameter or smaller to a semi- rebonded type magnesia-chrome brick containing electrofused magnesia-chrome clinker in a specific amount. SOLUTION: The Al2 O3 component most increases its strength among additives added to the semi-rebonded type magnesia-chrome brick consisting mainly of the electrofused magnesia-chrome clinker. Since the Al2 O3 component easily forms a low melting point compound together with CaO component contained in a slag, an effect by the addition of a slight amount of the Al2 O3 component is necessary, and the hot flexural strength increases with the increase of the addition amount. The peak addition amounts of the additives are however different each other in response to burning conditions and the reactions of the additives with other components in the brick, and the smaller the diameter of each additive is, in the smaller amount the effect is obtained.  The fine Al2 O3 powder having an average particle diameter of <=5 μm is added in an amount of 1-5 wt.% to the semi-rebonded type magnesia-chrome brick containing >=60 wt.% of the electrofused magnesia-chrome clinker.

Abstract: PURPOSE:To easily cut and remove a metallic ring from the main body of a picture tube without causing a damage to the main body of the picture tube even if the metallic ring is mounted to a position out of the tolerance, by providing an externally protrusive folded part in the metallic ring for tightening a panel skirt part. CONSTITUTION:Partially on a tightening metallic ring 2 having mounting lugs 3 a folded part 4 used as a cut place is provided. When a mounting work of shrinkage fit for the metallic ring 2 to a main body 1 of a picture tube is correctly performed, any further work is not required, however, when the metallic ring 2 has been mounted to the body 1 in a state with the lug 3 at least the tolerance apart from a prescribed position, a rework of mounting the ring to the correct position must be performed. At this time, if the folded part 4 is cut off at the position of a line 5 that shows a cut place, the tightening metallic ring 2 can be easily removed from the main body 1 of the picture tube. To give a strength to the folded part 4, a less amount of deformation can be obtained if the folded part 4 is formed in a dimension with its vertical angle alpha=90 deg. and legnth of its side l= about 5mm..

Filed: 1981-07-17
Abstract: PURPOSE:To prevent the malfunction occuring in the state of an original picture in a copying machine that can correct exposure automatically by providing a limiter that limits the rate of correction. CONSTITUTION:Photodetector arrays 33, 35 are disposed near a photosensitive drum 32 as means of controlling the light emission voltage of a light source 22 for copying the aperture card 19 on an original platen 21. When the outputs of said arrays are inputted to a photometric control part 26 for quantity of light, said outputs are compared with a reference voltage and a lamp control part 24 controls the applied voltage upon a lamp so that no photographic fogs are generated in the min. output parts. A limiter is provided for said comparison means with the reference voltage, and since the quantity of the light of the lamp is controlled to the extent that copying is at least assured despite the wrong recognition of the drop-out part as a background part, no wasteful copies are made even with the originals of peculiar ratios between the bright and dark parts.

Title: Memory card device
Inventor: URAHASHI KAZUJI
IPC: G06K19/00
Filed: 1988-05-07
Abstract: PURPOSE:To easily check the holding voltage of a data holding power supply from the external and to accurately judge the replacing period of the power supply by providing a liquid crystal panel connected to the data holding power supply and a constant voltage diode in a device main body. CONSTITUTION:The liquid crystal panel 11 connected to a feeder 5 through the data holding power supply 4 and the constant voltage diode 10 is stored in the device body 1. The boundary voltage value VB of the power supply 4 for changing a voltage to be supplied to the diode 10 is set up to a value higher than the lower limit value VC of the holding voltage allowing data in a memory circuit 2 to disappear. Thereby, voltage is supplied from the diode 10 to the panel 11 in the range of an initial voltage value VA of the holding voltage of the power supply 4 which is higher than the value VB, and the panel 11 continuously executes light shielding operation. When the holding voltage of the power supply 4 is dropped and reached to the value VB, voltage supply from the diode 10 to the panel 11 disappears and the light shielding operation is switched to light transmitting operation. Thus, the approach of the holding voltage of the power supply 4 to the lower limit value VC can be detected, and the replacing period of the power supply can be accurately judged.
