IPC: G03G15/04
Filed: 1989-11-20
Abstract: PURPOSE:To always keep a CPM within a prescribed extent and to prevent the reduction of reliability by measuring the time of one-cycle copying and delaying the driving timing of an optical system and disposing a dormant period in the case that the CPM is out of an allowable value. CONSTITUTION:When it is detected that the return speed of the optical system is accelerated and a copying time becomes shorter than the allowable value in the case that the CPM becomes larger than the allowable value by the cause of heat generation in copying, a copying time correcting command is transmitted to an optical system controlling part 18 by a copying time controlling part 17. When the copying cycle starts at a time (t0) a 1st sheet feeding roller 11 is rotated so as to pull a transfer sheet on a transfer tray 10 into a copying machine, on the other hand, an exposure lamp 3 emits light. When the transfer sheet reaches a 2nd sheet feeding roller 12 at a time (t1) and stops, the copying condition is met. The scanning of the optical system is immediately started by the optical system controlling part 18 in an original state, but in this case, the dormant period for a prescribed period is disposed by using a timer 19. Thus, the CPM can be surely prevented from being off-specification.

Title: Image coder and image decoder
Inventor: KIMURA JUNICHI
IPC: H04N19/60
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To obtain a reproduced image with an increased sense of naturality by dividing each block into (n) parts, interpolating picture elements of each divided part, producing n-sets of blocks and applying coding processing to the generated blocks. SOLUTION: A signal denoting whether or not division is made is given to a coder 7 as a division discrimination signal 54, in which the signal is coded and transmitted. The division discrimination signal 54 is a signal in one-bit in one block (64 pixels) and so much effect is not caused to the coding efficiency even when the signal is sent as it is. On the other hand, the signal denoting a division form is given to the coder 7 as a division form signal 53, but the signal is 1-bit per one pixel, then high efficiency coding is essential. In this coding, two areas are represented respectively by 0, 1 and number of consecutive Os and number of consecutive 1s are subject to variable length coding and the result is sequentially transmitted. In this case, an area at an upper left of a block is defined to be 0, then the redundancy is much more compressed.

Title: Bottle mouthpiece and cap generating scent
Inventor: KATOU YASUKIYO
IPC: B65D1/02
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To lead scent constituents to a nose to cause the scent to be effectively smelled with a small amount so that tea containing a little saccharic elements can be tasted sweet like tea with sugar and can be prepared in a taste different from actual contents by adding a function for generating a scent to a bottle for drinking in which a human mouth touches a mouthpiece of the bottle. SOLUTION: A storage space 4 is formed at an upper end 3 of a mouthpiece 2 of a bottle 1, and a scent generator 5 is placed here. While a cap is fastened normally, a hole of the storage space 4 is closed by a flexible substance on the rear of the cap, so that no scent molecules may leak. When the cap is removed and contents of the bottle 1 are to be taken, the scent molecules generated from the generator 5 scatter in the air. Therefore, since a nose is positioned very closely to the generator 5 at the time of drinking, the scent molecules can be effectively smelled by the nose. The generator 5 at this time may be formed of felt for example with the scent molecules infiltrated. On the other hand, the scent generator may be placed on a side of the cap.

SOLUTION: When a receiving signal '2' is inputted to a terminal 1101, metric values 4, 5, 0, 9, 11, 6 and 11 are outputted to terminals A to H of a selector 1138. Because an input signal is 2, a Max value is outputted to terminals I, L, M and P of the selector 1138. D terminals of comparators 1139 and 1141 are 1 and D terminals of comparators 1140 and 1142 are 0. Then, path memory 1147 of a state 0 is shifted to the left and 0 is written in a bit at a right edge, the value of the memory 1147 of the state 0 is loaded to path memory 11148 of a state 1 and is shifted to the left and 0 is written at a bit at a right edge. In this way, path memory 1147 to 1150 of each state store user data which correspond to survival paths that reach each state.

Title: Leading edge compensation circuit for color signal reproduction circuit
Inventor: NAGANO YASUYUKI
IPC: H04N9/89
Filed: 1986-12-18
Abstract: PURPOSE:To prevent color smear at a part just behind the part where a reproducing signal is missed from being generated, by providing a constant voltage generation circuit that generates a center voltage which sets the oscillation frequency of a variable oscillation circuit at a center frequency, and a constant voltage attaching switch which supplies the center voltage to the control input of the variable oscillaton circuit during a period where the reproducing signal is missed. CONSTITUTION:The constant voltage generation circuit 15 is formed by connecting a first resistance (R1) of 5.6KOMEGA, and a second resistance (R2) of 3.6KOMEGA between a power source of 5V, and the earth. Furthermore, a device is constituted so that the constant voltage output is inputted to a low-pass filter 7 through a switching transistor Q, and the switching transistor Q inputs and releases a tape loading completion detecting output generated continuously by a tape loading completion detecting means 16 in a state of completing the loading of a tape. Therefore, during a period while the switching transistor Q is energized, the control input of 3.2V drops to the center voltage of 2.5V, and the variable oscillation circuit 8 oscillates at the center frequency stably. In this way, since a pull-in state is generated against a stable reproducing video signal immediately after the completion of tape loading, no color disturbance is generated on a reproducing picture plane even immediately after the releasing of a short mute period.

Filed: 1990-11-08
Abstract: PURPOSE:To suppress vibration transmitted to a crossbar at the time of ON-OFF operation for making the locking amount of a pawl proper and thereby to prevent mistrip by providing a stopper part, which restricts the reset position of a trip crossbar, in a main body case. CONSTITUTION:Even vibration due to open and close operation of a movable contact 1 is transmitted to a latch support 9, as a projection 20b does not contact with the latch support 9, a trip crossbar 20 does not rotate and a mistrip is not generated. The latch support 9 is restricted in its dimension tolerance with respect to a side plate 5 positioned on the basis of a main body case 4, and a pawl 22 is restricted in its dimension tolerance with respect to the crossbar 20 whose rotation position is restricted by a stopper part 24 of the case 4. Consequently, as positions of the latch support 9 and the pawl 22 are restricted by the same reference, dispersion of both locking amounts is minimized, mistrip due to insufficiency of locking amount is eliminated and taking out characteristic is stabilized.
