Title: Magnetic tape cassette loading device
Inventor: TANIGUCHI YOSHINOBU
IPC: G11B15/675
Filed: 1986-10-16
Abstract: PURPOSE:To make optimum the timing when a cassette is moved to two positions by constituting such that the completion of the insertion of the tape cassette is detected and such that a cassette holder goes down to a tape travel position by driving a cam and a follower. CONSTITUTION:The cassette is inserted in a direction A1. At the end position of the cassette a motor is driven. Due to the rotation of the cam 112 the follower 133d turns counterclockwise with a shaft 133c as a center, and a moving member 124 moves in a direction F2. Thus, a driving member 137 turns counterclockwise, and a moving member 146 moves in a direction F1 and a longitudinal member 144 in the direction A1. An elevation lever 148 can turn with the shaft 11b2 of a side wall 11b as a center, and turns to the left due to the move of the member 144 in the direction A1. Then the cassette holder 14 moves in a direction E2 through a hole 148a and a pin 91b, and shifts to a tape travel position. Hence the timing when the cassette holder 14 is moved to the tape travel position from a cassette insertion completion position is optimized. Besides to that, the holder 14 can be elevated smoothly without noise.

Title: Frame synchronizing circuit
Inventor: NIWA YUJI
IPC: H04J3/06
Filed: 1988-09-28
Abstract: PURPOSE:To reduce a circuit scale by selecting an initial value depending whether a frame synchronizing pulse is fed to a counting means or not and detecting different counts with a common counting means to obtain a frame timing signal and a synchronization step-out signal. CONSTITUTION:An (N+1)th-ary counting means is provided when a frame synchronizing pulse is N-bit, and selects M+1 when no frame synchronizing pulse is inputted and M when the pulse is inputted as an initial value with a selection means 2. When the frame synchronizing pulse is fed to a counting means 4 via an OR means 3, the count is started from the initial value M. Then a frame timing signal representing the location of the frame synchronizing pulse is sent by detecting a count (N-1). When no frame synchronizing pulse is fed to the counting means 4, the counting means starts counting from (M+1). When the count reaches a value N, the out of synchronism detection means 5 detects it to generate the synchronization step-out signal.

Title: Method of raising temperature of fuel cell power generating device
Inventor: NISHIGAKI HIDEO
IPC: H01M8/04
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To pass an inert gas overheated by a reformer to a CO transformer and a desulfurizer through different passages, and independently raising the temperatures of the CO transformer and the desulfurizer to shorten the temperature raising time. SOLUTION: In starting of a fuel cell power generating device 1, a nitrogen gas 5a overheated by a reformer 73 is passed by a circulating route of the reformer 74 → a first bypass passage 22 → a preheater 71 → a blower 5 and a different route of the reformer 74 → a CO transformer 76 → a second bypass passage 24 → the blower 5. Thus, the heating of a desulfurizer 72 through the preheater 71 and the overheating of the CO transformer 76 are simultaneously progressed in parallel. Since the nitrogen gas 5a passed through the CO transformer 76 and reduced in temperature is never passed to the preheater 71, the heating of the desulfurizer 72 is accelerated. Thus, the temperature raising time in operation start can be shortened.
