Title: 4-phase quadrature modulator
Inventor: SASAKI YASUFUMI
IPC: H04L27/20
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To secure the isolation between 2-phase modulators by preparing a substrate containing plural layers of 2-phase modulators which divide a carrier into two carriers having a specific phase difference and modulate the divided carriers based on a modulating signal and holding a perfect conductor layer between both 2-phase modulators. SOLUTION: The 2-phase modulators 22 and 23 are provided on a substrate of a 5-layer structure and hold a perfect conductor layer between them. A hybrid circuit 21 divides a carrier signal inputted via a terminal 11 into two signals which have the same amplitude and a phase difference of 90 degrees. These two carrier signals are inputted to the modulators 22 and 23. The modulator 22 outputs the carrier signals in the same phase or opposite phases according to the polarity of an I-channel signal inputted via a terminal 13, and the modulator 23 outputs the 2-phase modulating signals according to the polarity of a Q-channel signal inputted vis a terminal 14. Then a synthesizer 24 synthesizes the vectors of those 2-phase modulating signals outputted from both modulators 22 and 23 with no change of phase difference between both signals.  Thus, a 4-phase quarature modulating signal is outputted via a terminal 12.

Abstract: PURPOSE: To provide a method and a device for monitoring the attribute of a file such as whether the file is read or not. CONSTITUTION: A computer system 100 contains multiple bit maps. A group bit map is kept for respective file index groups and the files contained in the group are designated. A user bit map 139 is kept for the respective users of the computers system 100 and the file of a file index 117, which is read by the user, is designated. When the user inputs a request for deciding which file in the selected group is checked and which is not checked yet, a logic AND operation is executed on the user bit map and a result bit map is generated. The computer system 100 decides an answer in the request of the user based on the content of the result bit map.

Title: Animated electronic conference room and video conference system and method
Inventor: NITTA TOHEI
IPC: H04N7/00
Filed: 1994-12-16
Abstract: PURPOSE:To show participants in animated characters or puppets in a conference and to enable the participants to control them by providing a means which sends and reproduces animation graphic control signals. CONSTITUTION:The participants are displayed as three-dimensional images. Each three-dimensional image is displayed in the shape of an animated character, a puppet, etc., as another person corresponding to the participant himself. Each user station sends and receive a voice signal S and an animation video control signal AV through a bus 36. A participant changes his image displayed on other participants terminals connected to a network watching his own image on his own terminal by using a characteristic control means 20. Consequently, the image of the conference participant photographed by a camera is not projected on other participant's terminals as it is, and each participant can control projected his own image and behavior by himself.

Title: Carbonization process and apparatus equipped with interchangeable inner furnace
Inventor: SHIBATA AKIRA
IPC: C10B53/02
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a carbonization apparatus which effectively and economically produces carbides and other products even when remnants generated from woodworking are employed as targets for processing. SOLUTION: A carbonization apparatus consists of three parts, i.e., a carbonization furnace, a combustion gas-utilizing system and a by-product recovering system. The carbonization furnace part, which is the main part, consists of an outer furnace 3 and a detachable, interchangeable inner furnace 11. The combustion gas-utilizing system uses the inner furnace 11 for preheating. Multiple inner furnaces 11 are assigned to each step, i.e., from material introduction to product transport. By allowing each inner furnace 11 to cycle transfer between each steps as one unit, all inner furnaces 11 may be treated in parallel. The volume of the inner furnace 11 is small for easy handling, and its structure is simplified to reduce the costs for equipment and manufacturing.

Title: Production of microlens array substrate
Inventor: YOTSUYA SHINICHI
IPC: H01L27/14
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To make easy mass production of microlens array substrates having rectangular pixels which are large in an effective aperture ratio and is substantially almost free from astigmatisms.

Title: Bathtub
Inventor: MACHIDA MITSUYOSHI
IPC: A47K3/02
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent impaired appearance of a bathtub by forming a surface layer exceeding a specified value in the contact angle between the surface thereof and water to keep the surface of an apron part hard to foul with scale. SOLUTION: A substantially transparent surface layer containing photocatalytic oxide particles, silicone and a water repelling fluororesin is formed on the surface of an apron part of a bathtub while the surface of the layer exceeds 90 deg.C in the contact angle between the surface of the layer and water. When a photocatalyst is optically excited onto the surface layer, an organic group bonded to a silicon atom in silicone molecules is partially replaced with a hydroxide group to present affinity to water and hence, a structure thus obtained has a part which presents affinity to water with silicone exposed to the outside air and a part which presents a water repelling property with the water repelling fluororesin exposed to the outside air both microscopically on the surface.  Thus, a hydrophilic as well as hydrophobic attachment will not be fastened onto the surface of a member to keep the surface clean. In other words, when the contact angle is set 90 deg.C, the clean condition is maintained according to the optical excitation of the photocatalyst thereby hindering the adhesion of water drops.

IPC: F01D11/08
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To reduce leak amount from the tip of a moving blade and improve efficiency of a turbine by providing a step whose root part has a curved shape and height is larger than curve radius of the root part at a position sandwiched between an inlet side fin and an outlet side fin on the outer periphery side of a shroud placed integrally with a blade on the tip of the moving blade. SOLUTION: A turbine moving blade 1 has a shroud 2 formed integrally with a blade on its tip, and a casing 3 surrounding the outer periphery of this moving blade 1 is provided with plural fins 4 axially. A step 9 whose root part 8 has a curved shape and height is larger than its curve radius is provided at a position sandwiched between an inlet side fin 41 and an outlet side fin 42 of the shroud 2 on such moving blade 1. Therefore, when working fluid passes through an inter-blade flow passage of the moving blade 1, a flow 10 enters the tip of the moving blade. Because this flow 10 passes through a micro flow passage 5 and then the flow's direction is forcibly changed to the radius direction by the curve surface of the root part 8, leak amount from the moving blade's tip can be reduced.
