Title: Portable video telephone system
Inventor: SABURI KAZUMITSU
IPC: H04W84/10
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To obtain a perfect reproduced image with no omission of encoding data caused even when a radio communication system is switched by monitoring the circuit state to selectively connect an optimum system to a dynamic image transmitter from a connectable communication system, switching automatically the optimum system to an optimum communication system based on the calling state and also changing the encoding processing system of dynamic images. SOLUTION: An antenna 100, a transmission circuit 101 and a reception circuit 102 are used for connection to a simple type telephone system, and an antenna 110, a transmission circuit 111 and a reception circuit 112 are used for connection to a portable telephone system respectively. A circuit quality detection part 105 monitors the circuit state and detects the circuit quality. Based on the circuit quality, a system control part 107 decides the radio communication system to be connected. The connecting destination is changed by a switch part 103. Then the connection is preferentially secured to the simple portable telephone system which can assure a high data transmission rate. As a result, the connection is secured to a 2nd preferential circuit even when a 1st preferential circuit has no idle channel.

Title: Pattern forming method
Inventor: MATSUOKA KOJI
IPC: H01L21/027
Filed: 1988-11-04
Abstract: PURPOSE:To obtain a vertical resist pattern which has a small film loss and no taper by development by applying resist and processing the surface with a solution of a compound with a photosensitive radical. CONSTITUTION:A substrate 1 is coated with the resist 2, whose surface 20 is processed with the solution 3 of the compound with a sensing radical and made insoluble to a liquid developer; and the resist 20 is exposed selectively, and developed with the liquid developer to remove the exposed part of the resist 2, thereby forming a pattern 2A of the resist. Thus, the resist surface is processed with the solution of the compound with the sensing radical to bind the sensing radical with the resin or sensing radical in the resist, and the resist surface is made insoluble to eliminate the film reduction in the development of the resist at the unexposed part, thereby evading the pattern defect at a mask edge due to light diffraction. Consequently, the resist pattern is formed in an excellent shape.

Title: Device for removing contaminated grains from body surface and method
Inventor: DARUSHII RORIMAA
IPC: H01L21/00
Filed: 1990-10-17
Abstract: PURPOSE: To remove very small particles from such surface as semiconductor wafer surface by, toward the direction of the surface of an object where a liquid to be removed is cleaned, removing a frozen liquid to be removed which has been frozen on the surface. CONSTITUTION: In a chamber, a cold air or cooling gas 24 such as nitrogen of a temperature lower than the freezing temperature of a liquid 20 to be removed is jetted. With the cooling gas circulated in the chamber, the liquid to be removed is frozen, so that it is condensed in a frozen state on contaminated particles or a frozen layer 21 is formed. For a pedestal or wafer chuck, after being periodically heated, for example, to 60 deg.C by such process as heating after being cooled to a low temperature, the particles bonded tightly to the surface are loosened. After the completion of the periodic freezing and heating process, the contaminated material particles are removed from a surface through dissolving by simply removing a freezing material under the effect of, for example, steam or liquid water and/or alcohol.

Title: Frequency divider circuit
Inventor: MINEO MASAO
IPC: H03G11/00
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To obtain a frequency divider which operates in a wide frequency band and on a broad input level by outputting a signal with constant amplitude despite the amplitude value of an input signal and making an output signal the input signal of a frequency dividing circuit. SOLUTION: An output limitation amplifier circuit 101 which always keeps an input level value constant is connected to the previous stage of a static frequency divider circuit 102, and the circuit 102 inputs an output signal of the circuit 101. A signal which is inputted to a frequency divider is amplified by the circuit 101. An output of the circuit 101 is limited and an output level is kept constant within a wide range of an input level. Even though the frequency divider circuit has a frequency that operates only in a narrow range of an input level, an input level of the circuit 102 of the next stage is kept constant despite the fluctuation of the input level of the circuit 101. Therefore, it is possible to perform a stable operation.
