IPC: H01L27/112
Filed: 1983-03-14
Abstract: PURPOSE:To enlarge the margin of a write voltage preventing the beak-down and improve the characteristic of repetition by connecting a device for controlling a impressed voltage to the output side of the following device, in an MIS field effect device having a charge capturing layer in a gate insulation film. CONSTITUTION:A voltage restricting device 30 is connected to a field effect device consisting of a write power source N1, a load MIS transistor T1 having a write data input gate N2, a selector MIS transistor TY1 having a selector input gate N3, and an EPROM cell transistor TM1.1 having a decoder input gate X1.1. In other words, an EPROM cell transistor TMn.1 is parallel-connected to the device 30, and the source or drain thereof is connected to the node N6 of the transistors TY1 and TM1.1. Thus, I-V characteristics 56 and 57 before and after the write of the EPROM load device only become 58 and 58' owing to the device 30, resulting in no generation of the device breakdown caused by impressing a high voltage.

Title: Ridge type semiconductor laser and manufacture thereof
Inventor: TAKAGI KAZUHISA
IPC: H01S5/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To inhibit reduction in the current blocking function of a ridge type semiconductor laser and reduction in the luminous intensity of the laser, by a method wherein current constricting layers are formed in the region of a first conductivity type clad layer, in which the intensity of a laser beam becomes the intensity of a laser beam of a value set in a specified range to the intensity of a laser beam in the central part of an active layer. SOLUTION: In a ridge type semiconductor laser, high-resistance circuit constricting layers 15 are arranged in an N-type InP layer (clad layer) 1 excluded with the lower region of a ridge part in a symmetrical manner holding the lower region of the ridge part between them so that a current, which is made to flow from an electrode 9 to an electrode 11, is collected in an active layer under the lower part of the ridge part. The intensity of a laser beam in the end parts of the layers 15 on the side of the lower region of the ridge part is set below 1/e of the intensity of a laser beam in the central part of the active layer.  As a result, electrons, which are injected through the electrode 11, are concentratedly flowed on the lower part of the ridge part, are bonded to holes, which are injected through the electrode 9 via the ridge part, in the vicinity of the active layer 4 under the lower part of the ridge part and the laser is emitted. Consequently, the generation of a reactive current can be reduced and the threshold current in the laser can be lessened.

Title: Focal plate having fresnel lens face
Inventor: TSUKADA SHINICHI
IPC: G03B13/24
Filed: 1993-02-06
Abstract: PURPOSE:To decrease the moires of the focal plate having a Fresnel lens face by constituting this focal plate in such a manner the second face is a lens-shaped curve nearly regularly arranged with lens-shaped curves and that weak irregularity is added to the face angles of the respective ring bands of the Fresnel lenses of the first face. CONSTITUTION:The fig. shows the optical characteristics of the Fresnel lens face 11 of this focal plate 10. The optical characteristics of a matt face 12 exhibiting a diffusion effect are omitted. While, heretofore, the rays emitted from one point A are converged to a point B by the Fresnel lens face 11, the rays emitted from the one point A are not converged to one point and are randomly varied around the point B by adding the weak irregularity to the face angles of the respective ring bands of the Fresnel lens face 11 in this embodiment. The point A is the center of the exit pupil of a photographic lens and the point B is the eye point of a finder system in the case of a camera. The rays correspond to the main rays of the photographic lens of the camera. As a result, the focal plate is not visible as if the minute parts are irregularly scattered on the matt surface and, in addition, the moires are decreased.

Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To obtain an internal medicine composition which can mask the original rust taste of iron and ensure a good taking property by adding a trivalent iron ion and a non-reducing substance. SOLUTION: This internal medicine composition contains (A) a trivalent iron ion (preferably a trivalent iron compound such as ammonium ferric citrate, ferric sulfate or ferric chloride) and (B) a non-reducing agent. The component B is a sugar alcohol (preferably sorbitol, xylitol, maltitol or erythritol). The iron content in the composition is preferably 0.5-60 mg (converted in iron ion in the iron compound) per day. Since the ingredient B has a laxative action, each dose is preferably 1-40g and set to the maximum non-action amount or less. The pH of the composition is 2.5-7.0. Thereby, the unpleasant rust taste which is originated from the iron and increases with the passage of time is reduced.

Title: Production of gypsum mold for casting
Inventor: KOIKE SUSUMU
IPC: B22C1/08
Filed: 1987-02-25
Abstract: PURPOSE:To improve casting mold strength and to prevent cracking thereof by drying the mold in an inert atmosphere in a drying stage for the gypsum mold. CONSTITUTION:Drying of the gypsum mold is executed in the inert atmosphere of gaseous N2, gaseous Ar, etc., at the time of producing said mold. Since drying is executed by maintaining the inert atmosphere in a drying furnace, the overcalcination of the surface of the gypsum mold is suppressed. The strength as the casting mold is, therefore, improved and the resistance to a stress difference based on the temp. difference between the surface and inside of the mold increases. As a result, the strength of the mold is improved and the cracking of the mold surface is entirely prevented.
