Title: Semiconductor optical device
Inventor: TANAKA TOSHIAKI
IPC: H01S5/042
Filed: 1988-12-26
Abstract: PURPOSE:To large enough take a modulation degree and to execute a very high speed modulation by applying an electric field in the direction being parallel to a layer against an nipi doping superlattice layer and controlling a band structure of a valance band and a conduction band and bringing about a large variation of a photoabsorption coefficient. CONSTITUTION:A p-type area layer 7 on which Zn is diffused by a diffusing method and an n-type area layer 8 on which Si is diffused are formed by utilizing a mask so that a current can be injected in the horizontal direction against a doping superlattice layer 4. Subsequently, a (p) electrode 9 and an (n) electrode 10 are made on the p-type area 7 and the n-type area 8, respectively. Thereafter, they are cut to a shape of an element by a cleavage, and a laser element of a light emitting area and an element in which an optical modulation area is formed are obtained on the same substrate. Subsequently, when about 1.3V is applied in the horizontal direction of the optical modulation area 20, a laser light of about 4 - 7mW light output is emitted. In such a way, a laser light intensity ratio can be taken high exceeding 100:1 in the case when an electric field is applied and in the case when it is not applied, and a high speed modulation whose modulation frequency is >=10GHz can be obtained.

Title: Pattern forming method
Inventor: HIRAIWA TOMOKO
IPC: G03F7/075
Filed: 1994-12-27
Abstract: PURPOSE: To realize a pattern of high accuracy through self-development by irradiation with excimer laser ray taking advantage of an organic compound thin film of high sensitivity. CONSTITUTION: A polyamide acid or a polyimide thin film possessed of at least either Si-Si bonds or Ge-Ge bonds in chains is formed as a photosensitive organic high-molecular thin film 1 on a prescribed substrate 2. The photosensitive organic high-molecular thin film 1 is irradiated with excimer laser ray in an oxygen-free atmosphere for exposure, and self-development is made to progress for the formation of a pattern. The patterned high-molecular thin film 1 is used as a resist film 1a, and a processed film 3 (e.g. carbon film) under the resist film 1a is dry-etched, whereby the accurately patterned resist film 1a is easily transferred to the processed film 3 for the formation of a processed film pattern 3a.  The high-molecular thin film 1 may be kept in either a polyamide acid state or a polyimide state at exposure, but it is higher in sensitivity in the former state than in the latter state. When the thin film 1 is finally used as a resist film or an interlayer insulating film, polyamide acid is turned into polyimide so as to enhance the film 1 in film quality.

Abstract: PURPOSE:To reduce the overhead of a software and to improve real time property by storing an A/D converted result for storage while switching the outputs of an analog terminal, designated register and terminal designating register for interruption by a switching circuit. CONSTITUTION:Assuming that it is desired to forcedly execute A/D conversion by using an input terminal AN while successively scanning channels 1-4 (correspondent input terminals AN0-AN3) by an A/D converter, a data is written from a CPU 9 to a terminal designating register 11 for interruption while A/D converting the channel 2 (AN1), for example. Thus, an interruption signal is outputted to the designating register 11 and an A/D control circuit 5 and according to the signal, the A/D control circuit 5 stops the current A/D converting (AN1) operation. Then, a control signal is outputted to a switching circuit 12 so as to switch the designating register 11 from an analog terminal designating register 8, and an analog terminal selecting circuit selects a terminal AN5. The control circuit 5 generates an A/D timing signal again and interrupts A/D conversion by using the terminal AN5.

Abstract: PROBLEM TO BE SOLVED: To provide a process simulation method for suppressing growth of micro oxide film thickness, and saving unnecessary calculation. SOLUTION: In an oxide film, an oxidant diffusion equation is solved, surface oxidant concentration at the interface of the oxide film and silicon is calculated (step 103). Growing film thickness in respective nodes on the interface is calculated. When the value is not more than a prescribed value, surface oxidant concentration at present time is preserved, preserved surface oxidant concentration is added at next time, and surface oxidant concentration is reset (step 104). The oxidized reaction speed of the interface is calculated by using surface oxidant concentration which is set again (step 105). The new interface is generated based on oxidized reaction speed (step 106), and the deformation of a form is calculated (step 107). Then, the steps 102-107 are repeated at prescribed time cut Δt until it becomes termination time (step 108).

Title: Coal ash plate
Inventor: SUGIYAMA TAKESHI
IPC: C04B32/00
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To eliminate the problem including troubles that particles themselves flocculate with air entrained in powder flocs, unreacted regions with water or incompletely mixed regions arise, coal ash as a principal raw material has poor wettability by water, etc., which result in insufficient hydration bonds after being formed and cured and therefore the low strength of plates because a conventional method for producing coal ash plates by using cement as a binder has not specified a kneading condition before forming or quantities of water and the like. SOLUTION: Compact and high-strength coal ash plates are formed by blending powder particles where cement as a binder is added to coal ash with the necessity minimum added of water, followed by carrying out operations of kneading them and mixing them together under a pressurized condition to perform pressure forming by means of a mold or die and then by curing. Consequently, the usage rate of added coal ash is profitably high and a special additive is economically needless, and compactness and high strength can be secured due to a contribution to cohesion between powder particles by the hydration bonds of cement particles and the pozzolanic reaction of coal ash particles.
