Title: Cassette tape recorder
Inventor: SHIMADA HIROMICHI
IPC: G11B15/48
Filed: 1984-12-06
Abstract: PURPOSE:To start the traveling of a tape traveling part under stable state by suppressing the start of tape traveling until a capstan motor is stabilized sufficiently at a low turning speed even if tape traveling operation is executed immediatedly after switching the tape traveling speed from high to low. CONSTITUTION:A time T1 set up by the 1st prescribed time generation part 8 has elapsed, the potential of an output point (b) is turned from the H level to the L level, a switch 71 is turned to the +B power supply side and braking to the capstan motor 5 is stopped. At that time, the turning speed of the capstan motor 5 is a slow turning speed or less and the capstan motor 5 is controlled so as to be rotated at the slow turning speed. When a time T2 set up by the 2nd prescribed time generating part 9 has elapsed, a start command for tape traveling is supplied from a traveling control part 3 to a tape traveling part 1 to start the slow tape traveling. In this case, the time T2 is set up to a time or more which is obtained by adding a time T3 required from the stopping state of the motor 5 to the sufficient stabilization at the slow turning speed status to the time T1.

Abstract: PURPOSE: To obtain a plastic pump dispenser for dentifrice that contains a viscous anti-bacterial, anti-tartar dentifrice containing an anti-bacterially effective amount of triclosan and an anti-tartar effective amount of polyphosphoric salt in a wall-partitioned distribution chamber. CONSTITUTION: A dental composition, such as a paste or gel dentifrice containing triclosan, as an antibacterial agent which acts to decrease plaque on the teeth, and polyphosphoric salt for anti-tartar actions, is packaged in a finger actuatable pump-type plastic dispensing container which is made of or includes a solid polymeric material, such as polyfluoroethylene, which is compatible with triclosan, so that excessive loss of its anti-plaque activity on storage is avoided, which losses have been notes when various other plastics have been employed as dispensing container component materials. Alternatively, others of such plastic may be employed for dispensing container parts when a stabilizer, such as a terpene, e.g. limonene, is present in the dentifrice.

In addition, a queued condition detecting means 8 detects the queued condition of the counter device, and gives a control timing signal for the counter 10, to the counter control means 9. As the result, an operation mode, which has been changed by the control of an operator, or by a control code from a high order unit, is initialized after a specified period of time has passed since the detection of the queued condition, and therefore, a printing output error due to the negligence of the confirmation of the operation mode can be prevented from happening.

Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To reduce the noise echo caused by the surface shape or the like of an inspected steel plate by quantizing the receiving signal from a split type vertical probe to store the same over a plurality of cycles and subjecting the same to synchronous adding and averaging processing. SOLUTION: For example, a split type vertical probe 3 generates ultrasonic waves based on the pulse signal from a pulse transmitter 2 and the receiving signal by the probe 3 of the reflected waves from the flaw or the like in an inspected object 4 is amplified to be digitalized. This digital signal is inputted to a synchronous adding and averaging processing circuit 7 to output an added and averaged result corresponding to a plurality of predetermined cycles. When a surface inferior to surface properties such as a grinder applied surface or the like is scanned by the probe 3, the noise echo appearing in the receiving signal is reduced by synchronous adding and averaging processing because random at every pulse repetition. If a charp wave sweeping frequency within a predetermined pulse width is used in a transmission pulse, detection resolving power is enhanced or an electrical noise echo is reduced.
