Abstract: PURPOSE:To reduce the circuit scale and to miniaturize a recording and reproducing device by generating a rotational frequency control signal, an index signal, and a ready signal by one detector output which detects rotation of a spindle or the like. CONSTITUTION:Narrow interval parts Y are provided in a part of a body X to be detected like a spindle, and a specific time range is generated by a timer circuit, and the rotational frequency control signal is generated in this time range. This time range is used to detect narrow interval parts Y of the body X to be detected and the index signal is generated, and the period of the detector output in the time range is counted to generate the ready signal. That is, the rotational frequency control signal, the index signal, and the ready signal are outputted by one detector output which detects rotation of the spindle or the like. Thus, the circuit scale is reduced to miniaturize the recording and reproducing device.

Title: Burner
Inventor: SUGANO TADAO
IPC: F23D14/62
Filed: 1989-11-15
Abstract: PURPOSE:To form a flame which creates no CO and no soot and is long and stable and reduce combustion noises by providing a flame hole on the downstream side of a premixing chamber, an opening which opens on a secondary air guide cylinder near the flame hole, and at the same time a tertiary air channel which goes through the central section of the flame hole and projects. CONSTITUTION:When the fuel gas from a combustion nozzle 3 and the air supplied by a blower 1 enter a premixing chamber 2, they mix together and flow to the sides of a flame hole 6. The other air passes through a secondary air channel 8 and it is divided by and supplied from the opening A7'' and the opening section B8' of a secondary air guide cylinder 7'. The mixture gas that is blown out from the flame hole 6 becomes a flame 13 by means of an ignitor 14. At this time the air from the secondary air channel 8 is supplied forcibly to the outer circumference of the flame 13 by the throttling section 12 of the opening section B8'. Further, tertiary air is supplied to the central section of the premixture gas from a tertiary air channel 15, and a flame 16 is formed on the downstream side of the central section of the flame hole 6. With this constitution in which air is supplied to the outside and inside of the premixture gas it is possible to provide stable combustion with no CO and no soot generated. And because of the long flame 13 formed in a combustion chamber 10 its inside is kept almost thermally uniform and at the same time it is possible to provide combustion with a low level of noises.

Filed: 1999-10-20
Abstract: PROBLEM TO BE SOLVED: To facilitate a timely stop switch operation in a slot machine. SOLUTION: In a special prize mode, a left pattern belt 12 is rotated at a low speed and the remaining two are rotated at a high speed in dividually at constant speed (figure 8 (a), thin line is low speed and thick line is high speed). Since the rotation speeds of the three pattern belts 12 are different, it is recognized that the special prize mode is started. When the left pattern belt 12 is stopped by the operation of a player, the speed of a center pattern belt 12 is changed from high to low (figure 8 (b)), and when the center pattern belt 12 is stopped, a right pattern belt 12 is slowed down (figure 8 (c)). Thus the player can confirm a pattern potted on the pattern belt 12 rotated at the low speed and perform a stop switch operation at an appropriate timing.  Even a person with poor moving object sight, a person not laying frequently and a beginner, etc., easily establish a special prize by the timely stop switch operation.
