摘要： PURPOSE:To plan to make a tone quality high with a simple constitution, by releasing a sound from a speaker box installed behind a PACHINKO machine from an opening portion of the front face of the PACHINKO machine through a duct or a phone. CONSTITUTION:Communicting holes of a speaker box 22 and a PACHINKO machine 2 are communicated by a duct 24, whereby a sound produced from a speaker unit 23 into the speaker box 22 is released to the outside from the communicating hole of the PACHINKO machine 2 through the duct 24. Here, as the speaker unit 23 housed within the speaker box 22, one with a relatively large bore can be used, so that it becomes possible to enlarge a reproduction range and a reproduced sound from the speaker unit 23 is released to the outside through the duct 24, thereby improving a low sound range. Since the speaker box is disposed behind the PACHINKO machine where there is a relatively vacant space, a degree of freedom in place for disposing the speaker box can be increased, and the restriction in size of the speaker unit can be accordingly lessened.

摘要： PURPOSE:To switch various operation modes with a simple constitution. CONSTITUTION:A switching arm 300 is made freely rockably in the horizontal direction and the vertical direction around a shaft 301, and by rocking the switching arm 300 in the horizontal direction, driving force is transmitted selectively to either side of an F reel gear 501 or an R reel gear 502. Further by rocking the switching arm 300 in the vertical direction, the driving force is transmitted to the F reel gear 501 or the R reel gear 502 through either side of a transmission gear 305 or 306 arranged coaxially. Thus, since the driving force is transmitted to the F reel gear 501 or the R reel gear 50 through either side of the transmission gear 305 or 306 arranged coaxially, various operation modes are switched with a simple constitution.

摘要： PURPOSE:To largely reduce the generation of leaking magnetic flux and to easily make dimensional accuracy. CONSTITUTION:A ring-like main magnet 3 is provided on a lower part plate 1 provided with a center pole 2, a ring-like upper part plate 4 is provided on the upper part of the main magnet 3 and respective components provided up and down with the upper plate 4 as a center are covered by a shield cover 7. Thus, a magnetic circuit 8 is constituted and further, a gap between the outer circumferential edge part of the upper plate 4 and the inner surface of the shield cover 7 is made as small as possible to be less than 0.5mm. Thus, by making the gap between the outer circumferential edge part of the upper plate 4 and the inner surface of the shield cover 7 as small as possible, since the magnetic potential difference between a frame 9 and the shield cover 7 can be made as small as possible, the generation of the leaking magnetic flux from the frame 9 towards the shield cover 7 can be reduced.

摘要： PURPOSE:To provide an EL display unit capable of being manufactured with a high yield, easily having a large screen, and having excellent reliability. CONSTITUTION:A light emitting element 40 is formed on the end face of an insulating base 10, an individual electrode 20 and a common electrode 30 connected to the metal electrode and transparent electrode of the light emitting element 40 respectively are formed on both faces of the insulating base 10 faced to the end face. Multiple insulating bases 10 are arranged face to face, and an X-Y dot matrix arranged with multiple light emitting elements 40 (picture elements) in the X-direction and the Y-direction is formed. Individual electrodes 20 of the insulating bases 10 are conducted by a lead 50 inserted into through holes formed on the insulating bases 10. The yield is sharply improved as compared with the case that the light emitting element 40 is formed on the plane of the insulating base 10. The size of a screen can be freely set by the number of arranged insulating bases 10.

摘要： PURPOSE:To provide a thermal head which reduces an influence exercised owing to a thermal strain and has excellent thermal response by a method wherein a base sheet is curved and a heat generating body serving as a working surface is positioned at a top. CONSTITUTION:A base sheet 1 on the one surface side of which a conduction copper pattern 2, a common electrode copper film 3, and a heat generating body 4 are formed is folded so that the heat generating body 4 is positioned at a top, and supported from the rear by means of a support 8. With this state, a heat-sensitive sheet is caused to pass as the sheet is brought into contact with the heat generating body to perform printing. A slight gap is formed in a position, where the heat generating body 4 is formed, between the base sheet 1 and the support 8 to form a heat insulating layer.

摘要： PURPOSE:To shift a voltage to a positive side when a video signal to be outputted from an amplifier rises by providing a feedback circuit to feed back a signal at the same level as the video signal to the inverted input terminal side of the amplifier. CONSTITUTION:When a video signal 3' is inputted to the non-inverted input terminal of an amplifier A2, a signal dropping a voltage for 0.6V by a potential drop correction diode D2 is fed back and inputted. Therefore, the output of the amplifier A2 is the signal which voltage is always higher than that of the video signal 3' by 0.6V. Then, the voltage of the output from the amplifier A2 is dropped for 0.6V by a diode D1 and supplied to a capacitor C3. Therefore, even when the cycle of the video signal 3' to be inputted to the non-inverted input terminal of the amplifier A2 is short, the signal at the same level as the video signal 3' is always inputted to the non-inverted input terminal of the amplifier A2. Thus, when the video signal 3' from the amplifier A2 rises, the voltage can be shifted to the positive side and even when a through rate is low, the peak of the input video signal 3' can be easily followed up.
