Title: Game machine
Inventor: SASAKI SHIGETO
IPC: A63F9/04
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To promote the desire to participate in a game. SOLUTION: A player inputs an expected combination of numbers using a keyboard. After air is fed upward by an air fan for a predetermined time, balls 12a, 12b on tables 56a, 56b are floated and rotated. Since the balls 12a, 12b are constructed of icosahedrons, their rotation is promoted and is further smoothened by the stepped parts 42a, 42b of cylinders 40a, 40b. When air is stopped, the balls 12a, 12b drop onto the respective tables 56a, 56b. The tables 56a, 56b are shaken to cause the balls 12a, 12b to land on normal positions. The combination of numbers is read by a sensor reading circuit, and a controller gives scores to the player who guessed the right combination of numbers.

Abstract: PROBLEM TO BE SOLVED: To increase electric conductivity of silicide material and improve the structure of an electrode and a wiring part which have a silicide junction and a silicide thin film, by forming the electrode or the wiring of a silicide thin film wherein the interstitial distance is changed by lattice distortion generated in the silicide thin film. SOLUTION: A metal thin film 12 is deposited on an Si substrate 11 and taken out in a vacuum vessel or in the air. A silicide thin film 13 is formed by silicide reaction with a heat region furnace or the like in an inert gas atmosphere. In order to generate lattice distortion in the formed silicide thin film 13, elements 14 are mixed from the outside. The implantation elements into the silicide thin film 13 are metal which generates and consitutes lattice distortion in the silicide thin film 13, and change the distance between Si atmos. Thereby, carrier conveying mechanism is changed, electric conductivity in metal silicide is increased, and the structure of an electrode and a wiring part which have a silicide junction of high melting point metal and the silicide thin film 13 is improved.

Abstract: PROBLEM TO BE SOLVED: To correctly restore a transmission signal from a transmitting device in a device for amplifying a reception signal to a desired level through the use of logarithm amplifiers and reverse logarithm converters. SOLUTION: In a receiving part for receiving modulation wave by a π/4-DQPSK system, the reception signal is amplified by a low noise amplifier LNA and the I component and the Q component of the reception signal are respectively demodulated by an orthogonal demodulator 20.

CONSTITUTION:By adding an output of peak level detectors 3 and 4, namely, levels M and N with an adder 17 of resistances 36 and 37, a slice level is made, this is impressed to a positive input of a comparator 5, on the other hand, an output of a peak level detecting device 2, namely, R is inputted to a negative input,and only when the level of an envelope R is lower than the slice level P, a high level is outputted to the output of the comparator, and a waveform (c) can be obtained. For the output of spots B and C for the servo a tracking error signal (b) is obtained through photoelectric converting devices 6 and 7, and a differential amplifier 8. Here, by signals (b) and (c), when the signal (c) is a high level, a negative feedback area of a tracking error signal (b) can be detected. Thus, since the slice level to detect the negative feedback area automatically follows even when the disk is different, the negative feedback area can be correctly detected.
