Title: Semiconductor surface luminescence laser with improved deflection control and transversal selectivity
Inventor: KENTO DENISU CHIOKUETSUTO
IPC: H01S5/042
Filed: 1994-03-29
Abstract: PURPOSE: To improve the lateral mode selectivity by constituting gain regions each having a specified aspect ratio in cross section to control the polarizing direction. CONSTITUTION: At the uppermost metallized contact 15 covering a rhomboid active region ADCD, the diagonal line AC is at least 1.2 times as long as the diagonal line BD. The active region shape is such that the main dimension is selected as the longest line segment passing the center of the active region in a cross section. The long (main dimension) diagonal line AC hence passes the center of the active region and the short (subdimension) diagonal line BD is the longest vertical line. A light generated in the active region is reflected between stacks 11, 12 and part of this light is emitted through a window 20. Owing to this active region shape, thus emitted light has preferentially a low order and is polarized in the main dimension AC direction.

Title: Copy material of photo- and heat-sensitive type
Inventor: KUNIKANE MAKOTO
IPC: G03C5/56
Filed: 1978-05-16
Abstract: PURPOSE:To increase the image density by combining special photosensitive sheets and image receiving sheets. CONSTITUTION:There is formed on a (semi-) transparent substrate a photosensitive layer which is composed mainly of a phenol or naphthol derivative A, a dye and a binder, thereby to form a photosensitive sheet. There are laminated on an opaque substrate a precoat layer, which is composed mainly of a zeolite represented by a molecular sieve as a porous adsorption reaction carrier for efficiently accomplishing the coupling reaction, and of a binder and an image receiving layer which is mainly composed of diazo compound, an alkali generating agent and an acid stabilizer, thereby to produce an image receiving sheet. The photosensitive sheet is exposed to an image to make the derivative A at the exposed portion non-sublimative and then is heated such that it is overlaid upon the image receiving sheet. The unchanged derivative A at the non-exposed portion is sublimated and transferred to the image receiving sheet so that it is subjected to the coupling reaction with the diazo compound at the portion, thus producing the image.

Title: Decoder
Inventor: TAKAGI YOSHIMITSU
IPC: H04N19/134
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain a decoder capable of minimizing the frame skipping of a picture on a sub-screen and decoding encoded picture data by means of a single MPEG decoding circuit by decoding encoded picture data of the main screen of the next frame soon when a prescribed time has passed even in the middle of decoding encoded picture data of the sub-screen. SOLUTION: A CPU 4 starts an incorporated timer 41 in order to measure a regulated time. Next, the CPU 4 controls a buffer selecting circuit 22 and supplies encoded picture data MV of the main screen to a picture decoding circuit 23 through the circuit 22 to make the circuit 23 start decoding. In the case of exceeding the regulated time of the timer 41, even while encoded picture data of the sub-screen are decoded, decoding of encoded picture data of the next main screen is started immediately. Thus, at the time of decoding the pictures of plural channels, all the frames can be decoded without frame skipping.

Title: Filter paper and air filter using the same
Inventor: SUMIOKA MASAYUKI
IPC: B01D53/46
Filed: 1995-03-17
Abstract: PURPOSE: To capture particles contained in a gas and even gaseous boron by dispersing glass fibers in an aqueous solution having a specific pH value by using an acid selected from among sulfuric acid, L-tartaric acid and others to make a paper in a wet state to apply the L-tartaric acid to this paper. CONSTITUTION: First, a paper is made in a wet state by dispersing glass fibers of 0.2 to 12μm dia. in an aqueous solution having a pH value by using an acid selected from among sulfuric acid, L-tartaric acid, nitric acid and citric acid. This filter paper is almost free from the elution of boron because the degree of deterioration of the glass fibers is low. In addition, the L-tartaric acid is added to the paper, so that both the L-tartaric acid and boron are chemically bonded. Consequently, the filter paper can capture particles and even gaseous boron. Further, the pH value of the aqueous solution for dispersing the glass fibers is adjusted by using sulfuric acid, so that stable salts with low volatility are formed and the filter paper is obtained without lowering the drying temperature therefor.

IPC: B28B7/28
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of an inner form and the deviation of a reinforcing strap from occurring during moving by fitting a square annular reinforcing strap onto the outer periphery of a long-size corner form member which is fixedly erected, in a freely attachable/detachable manner, between the corner parts of a fitment each for a square framelike pillar foot and a square framelike pillar head arranged opposite to each other at a specified interval, and press-holding an intermediate form structure blocking a space between the adjacent corner forms using bags introduced inward. SOLUTION: An intermediate form structure is arranged, in a dividing fashion, in eight spaces S1, S2 of the total nine spaces S1, S2, S0 segmented in the form of a lattice. In addition, an intermediate form member 43 is formed of a flexible material such as rubber into a long- size platelike shape and at the same time, has a projecting cotter formed on the surface and arranged in contact with the inner peripheral face of a reinforcing strap 22. Further, the width of each intermediate form member 43 is formed to the width corresponding to the inside measurement of each space S1, S2. Auxiliary form members 45 cover the periphery of a middle lattice reinforcement 21a, leaving no gap in between so that concrete is prevented from leaking out of the intermediate form members 43.  Air bags 47 are made of a slender rubber of rectangular parallelepiped and introduced into the spaces S1, S2, S0 to press-hold the members 43. Thus it is possible to prevent the deformation of the inner form and the deviation of the reinforcing strap from occurring during during moving.

IPC: F02D41/14
Filed: 1988-03-11
Abstract: PURPOSE:To prevent an air-fuel ratio feedback control amount from its excessive correction by transferring air-fuel ratio to a target side promptly by a skip correction amount, when a lean side or overrich side inversion period is in the predetermined period or more, while gradually by a fine correction amount when the inversion period is in the predetermined period or less. CONSTITUTION:Being based on a detecting result of an air-fuel ratio detecting means M3 in the downstream of a ternary catalyst M2, when an internal combustion engine M1 is in inversion in a lean or overrich side, a control amount, corrected to be adjusted by a skip correction amount promptly invertably respectively determined independently, is instructed by an air-fuel ratio feedback control means M5 to an air-fuel ratio adjusting means M4. Now when a decision means M6 decides a lean side or overrich side inversion period to be placed in a short period inversion condition less than the predetermined inversion period, the skip correction amount is changed to a correction amount, able to fine change air-fuel ratio, by a changing means M7, and the air-fuel ratio is gradually transferred to a target side. Thus surely preventing an air-fuel ratio feedback control amount from its excessive correction, exhaust purifying performance can be enhanced by improving control accuracy.

Abstract: PROBLEM TO BE SOLVED: To realize a multicarrier radio receiver in which radio communication in the multicarrier system is conducted in an excellent sate even on the occurrence of frequency selective fading. SOLUTION: Plural gain variable devices 108 corresponding to radio carrier frequencies are provided to a post stage of a distributer 107 distribtuting a reception signal into plural radio carrier frequencies and the gain of them is controlled for each radio carrier frequency.
