Title: Tape cassette
Inventor: KOSEKI TSUTOMU
IPC: G11B23/087
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To reduce the running failure of a tape due to the winding disturbance and to improve the productivity by making the roughness of the surface of a friction sheet in contact with the magnetic tape to be larger than a specific value. SOLUTION: A pair of taking up and supplying hubs 4 wound with the magnetic tape 7 is housed in the tape cassette 1 consisting of upper and lower halves 2, 3, then the friction sheets 10 are mounted in both spaces between the hubs 4 and upper half 2 and between the hubs 4 and lower half 3. The roughness Ra of the surfaces of sheets 10 in contact with the tape 7 is defined as 0.5-5μm. When the roughness Ra is smaller than this range, the friction coefficient is increased due to the smoothness of the surface, and the satisfied running property is impaired. Polyester sheets such as a polyethylene terephtalate, polyethylen naphthalate, etc., are used for the forming material of the sheet 10 in consideration of the precision at the time of molding. The friction coefficient of the sheets 10 against the tape 7 is defined as <=0.48.  Thus, the failure of running property due to the winding disturbance, etc., is prevented, and the productivity is improved because the workability of the sheets is increased.

IPC: H04Q3/58
Filed: 1987-09-16
Abstract: PURPOSE:To prevent a fault of talking due to setting and release left undone by automating 'absence setting' based on the illuminance around each key telephone set. CONSTITUTION:An optical sensor 4 is fitted to the surface of a key telephone set 1 and generates a voltage proportional to the illuminance around a location where the key telephone set 1 is placed. The voltage generated from the optical sensor 4 is converted into a digital data by an A/D converter 5 and inputted to a control circuit section 2. The control circuit 2, based on a digital data from the A/D converter 5, decides whether or not the data value is smaller than the preset value and sends a data of 'absence setting' to a key telephone master set 7 through a data line 6 when smaller. Thus, the setting left undone at seat leaving or the release of absence setting left undone at come back is prevented.

Title: Signal generator
Inventor: MITSUOKA MASAHIDE
IPC: H03K4/02
Filed: 1984-10-31
Abstract: PURPOSE:To set easily an optional waveform with simple constitution by adding the 1st 3rd reference voltages with weighting. CONSTITUTION:An operational amplifier A1 amplifies a voltage difference between the 2nd reference voltage V1 and the 1st and 3rd reference voltages W (V0, V2) subject to weighting and the result is fed to each voltage dividing point of a voltage divider D1 via distribution resistors R1h-R1j. Thus, the voltage of each voltage dividing point of the voltage divider D1 changes from the state that it is distributed at an equal interval (linearly) between the 1st and 2nd reference voltages V0 and V1 to the state that it is distributed at an unequal interval (nonlinearly) by addition with weighting. A nonlinear waveform by a step wave approximation appears at an output terminal OUT as shown in solid lines through the sequential closing of step switches St-S14. A linear step wave shown in broken lines in the figure is obtained by making the distribution resistors R1hR1j infinite.
