Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of providing changeable display of more fun to a player, and providing a game of more fun to the player. SOLUTION: A reversed pattern number is renewed for every starting winning by a reversed pattern number counter, and when generation of a reach (ready- for-winning) condition is decided, a reversal starting pattern is determined based on the reversed pattern number at the time and an expected stopped pattern (S73-S77). The scroll direction of the pattern is changed at the timing when a displayed pattern becomes the reversal starting pattern. Timing to change the scroll direction thus becomes random based on relation between the reversed pattern number when the reach condition is decided and the expected stopped pattern.

Title: Semiconductor memory device
Inventor: TERADA YASUSHI
IPC: G11C7/00
Filed: 1985-08-06
Abstract: PURPOSE:To prevent an erroneous writing without requiring a timer by controlling a period of an external writing cycle by an external period control signal. CONSTITUTION:When an output of a signal output pin 11 is high level, a write enable signal the inverse of WE falls and then a program control circuit 8 starts an external writing cycle and when the write enable signal the inverse of WE is low level, the program control circuit 8 operates the signal output pin 11 as a signal input pin. Namely, while the write enable signal is low level, when a high level is externally impressed to the signal output pin 11, the program control circuit 8 continues the external writing cycle. When a low level is externally impressed to the signal output pin 11, the program control circuit 8 completes the external writing cycle and moves to an internal writing cycle. Thereby, a timer for controlling a period of the external writing cycle is not required but an erroneous writing resulting therefrom can be prevented.

Title: Relative humidity detector for iodine removing filter
Inventor: TAOKI MASAFUMI
IPC: G01N25/64
Filed: 1984-08-24
Abstract: PURPOSE:To detect relative humidity of an iodine removing filter not affected by a high-temperature gas, by providing a thermometer and a relative humidity meter for detecting the atmosphere temperature and relative humidity of a treated gas while a thermometer is set at an iodine filter inlet as connected to an arithmetic unit. CONSTITUTION:An arithmetic unit 17 calculates absolute humidity from outputs of a relative humidity meter 5 and a thermometer set at a treated gas inlet. As the absolute humidity and the total pressure is constant at any point in the system, the relative humidity gives a function only for the temperature. The relative humidity is calculated with the arithmetic unit 17 from the output of a thermometer 4 set at the inlet of a iodine filter 1. Thus, a relative humidity meter 6 is set at the location free from the effect of heat radiation from a heating source 3 thereby enabling accurate measurement.

Title: Position control device of video head
Inventor: ARISE MASANOBU
IPC: G11B15/467
Filed: 1982-10-05
Abstract: PURPOSE:To shorten a lock-in time required for tracking by changing temporarily a circulation order when a phase of a circulation order of frequency of the third signal is different greatly from a circulation order of the frequency of a tracking signal. CONSTITUTION:When the frequency of an automatic frequency control oscillator 23 is denoted as f1, and frequency of a band pass tracking signal is denoted as f2 or f4, signal components of f2-f1=15KHz (the first signal) and f4-f1=45KHz (the second signal) are obtained in an output of a mixer 24. In case when the frequency of the oscillator 23 is f1 or f2, and the frequency of the tracking signal is f3 or f4 in accordance with said frequency, a signal component of -f3-f1-= 60KHz, or -f4-f2-=30KHz (both are the third signal) is obtained. The third signal is detected, sets a TR34 to an on-state, and an oscillation control switch 36 is switched to a contact 36C. Therefore, as for the frequencies of the oscillator 23, f1 and f3, or f2 and f4 are replaced, and tracking can be taken instantaneously. That is to say, when the oscillation frequency of the oscillator 23 is made to coincide with the frequency of the tracking signal by which a head 21 is reproduced at the present time point, the lock-in time of a tracking error is shortened.

Title: Multi-file processing control system
Inventor: NANBA MASAO
IPC: G06F12/00
Filed: 1989-07-05
Abstract: PURPOSE:To improve the file processing performance by providing many files as a bit map table on a main storage device in a certain sequence and with 1:1 correspondence secured among those files. CONSTITUTION:A bit map production part 121-1 assigns plural bit maps into a bit map table area 131 of a main storage device 13 in that order and in accordance with plural files prepared in an auxiliary storage 10 based on a certain sequence. Thus a bit map table is produced. A bit map control part 121-3 retrieves the area 131 and a file processing part 121-4 performs such file processes including a process where a file stored in the storage 10 is saved to a magnetic tape via a file processing area 132. Thus an even and large file processing area is secured for use of a file process. Thus, the file processing performance is improved.

Title: Knock detecting method and device for internal combustion engine
Inventor: AOKI KEIICHIRO
IPC: F02P17/12
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To improve knock detecting accuracy by easily separating a knock vibration component and a combustion fluctuation noise component from each other when the knock vibration component is extracted from an ion current output signal. SOLUTION: An ion current detecting circuit 15 can detect ion current under a condition that a higher frequency component of knock vibration is included since an ignition coil, secondary side 1b does not exist in a pass that ion current flows. A BPF 17 can certainly remove combustion fluctuation noises in different frequency zones by only extracting the higher frequency component of the knock vibration. A CPU 10 judges an existence of occurrence of knock on the basis of the higher frequency component of the knock vibration. As a result, a state that the wrong judgment of existing knock caused by unstable combustion at the time of EGR execution or low middle load, can be certainly avoided, and knock detecting accuracy can be improved.
