Title: Pachinko machine
Inventor: SAKASHITA KAZUYUKI
IPC: A63F7/02
Filed: 2000-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a game machine which not only decides whether an alternative result is simply a jackpot or an out when a REACH (ready-for-winning) symbol mode is displayed but also gives a diversified profit mode to improve game interest.

Title: Infrared sensor
Inventor: HATA HISATOSHI
IPC: H01L37/02
Filed: 2000-06-15
Abstract: PROBLEM TO BE SOLVED: To provide a thermal infrared sensor which has superior infrared-absorbing efficiency, high sensitivity, small heat capacity of a detecting part and superior response characteristics. SOLUTION: An infrared-absorbing film 26 is formed on the detecting part of this thermal infrared sensor. An infrared-reflecting film 24 is formed on a semiconductor substrate 10 below the detecting part. An optical distance between the infrared- absorbing film 26 and electrodes 22a and 22b is made approximately a quarter of wavelength of detection infrared rays at a partial region of the detecting part 6. The optical distance between the infrared-absorbing film 26 and the infrared-reflecting film 24 is made approximately a quarter of the wavelength at the remaining region of the detecting part 6. A resonance structure is formed between the electrodes and the infrared-absorbing film by positively utilizing an infrared-reflecting function of the electrodes 22a and 22b, so that the infrared-absorbing efficiency is enhanced.  Since the electrodes are formed on a limited part of the detecting part, and the resonance structure is formed between the infrared-absorbing film and the infrared-reflecting film in the remaining region, an increase in thickness of the detecting part is suppressed and a decrease in response characteristics can be prevented.
