Abstract: PROBLEM TO BE SOLVED: To reduce distortion at a drum base by establishing a specific dimensional relationship among plural fastening holes, which are not located on the same straight line to join and fix the base to a chassis, and the projected members which abut against the chassis of the drum base to control the height of the base against the chassis. SOLUTION: Through-holes 2d and 2e of a drum base 2 have bosses 2d-1, 2d-2 and 2e-1, 2e-2 which have smaller diameters than the holes 2d and 2e and are arranged on both sides of the holes on a straight line L1 that connects the center of the holes 2d and 2e. A through-hole 2f has ribs 2f-1 and 2f-2 which have smaller sizes than the hole 2f in the direction normal to a line L2 that is in parallel with the line L1. Through-holes 2g and 2h are engaged with the positioning pins of the chassis, the bosses and the ribs are abutted against the chassis and the base 2 is screwed onto the chassis through the through-holes. Thus, distortion at the base 2 is suppressed, and head contact and the track pattern are improved.

Title: Magnetic recording circuit for digital signal
Inventor: SASAMOTO MANABU
IPC: G11B5/09
Filed: 1993-04-28
Abstract: PURPOSE:To surely record a digital signal containing a DC component on a magnetic tape by nearly equalizing the cut-off frequency of A high band side of a lag lead filter with the cut-off frequency of the low band cut-off characteristic occurring due to a transformer and a magnetic head. CONSTITUTION:The digital data are converted to a digital signal with a required code format in a modulation circuit 5, and the lowering in a low band component due to the low band cut-off characteristic occurring due to the rotary transformer 3 and the magnetic head 2 is compensated by emphasizing it previously in a low band cut-off characteristic compensation circuit 6 to be sent to a recording amplifier 4. The digital signal converted into a current by the recording amplifier 4 is transmitted to the magnetic head 2 through the rotary transformer 3 to be recorded on a magnetic tape 1. Thus, the low band cut-off frequency of the frequency characteristic of a recording signal transmitted to the head 2 becomes lower than the cut-off frequency of the low band cut-off characteristic occurring due to the transformer 3 and the head 2, and the digital signal containing the DC component is recorded on the magnetic tape 1 surely.

Filed: 1992-04-22
Abstract: PURPOSE:To make a recording paper easily spread in a thrust direction and to prevent the generation of wrinkles by providing a heat resistant fiber in the thrust direction on the surface of a pressure roller. CONSTITUTION:The heat resistant fiber 22 is provided in the thrust directions on the surface 21 of the pressure roller 20, and it is provided zigzag in a radial direction R all over the surface 21.

Title: Switched capacitor circuit
Inventor: YASUDA SUSUMU
IPC: G11C27/02
Filed: 1988-04-25
Abstract: PURPOSE:To prevent the generation of a DC offset by constituting an input capacitor so that a transistor(TR) having the same size as a TR connected to an inverted input terminal of an operational amplifier to a non-inverted input terminal. CONSTITUTION:When a clock signal phi1 is turned from a high (H) level to a low (L) level in a switched capacitor circuit, charge is drawn by the parasitic capacity of a TR M5 and charge is also drawn by that of a TR M8. Since the sizes of the TRs M5, M8 are the same and the capacity of the capacitors C2, C3 is the same, voltage changes due to charge drawn from respective TRs are applied to two input terminals of an operational amplifier A and a DC offset is not generated. When a clock signal phi2 is turned from L to H, charge is injected into TRs M4, M9 through respective parasitic capacitors. Since the sizes of the TR M4, M9 are the same, voltage changes due to the charge injected from respective TRs are applied to respective input terminals of the operational amplifier A with the same phase. Thereby, no DC offset is generated.

Filed: 1985-05-15
Abstract: PURPOSE:To reduce a useless waiting time due to control program reading by activating previously a terminal equipment with the aid of a timer before data transmission work begins actually between a host computer and the terminal equipment. CONSTITUTION:When data transmission work before one cycle is terminated in a time t4, immediately a terminal main body 23 outputs an impulsive power source disconnecting signal PW-OFF through an interface in a time t5 without data processing work of the terminal itself. Then a flip-flop 29 is reset through an OR gate 28, and a Q output terminal comes to 'L' level. A transistor 31 is disconnected to release a relay 22, and accordingly power supply to a main body power source circuit 24 is disconnected. When the power supply is interrupted, a power failure detecting circuit 27 acts and outputs a power failure detecting signal DE. Receiving said signal, the terminal main body 23 calculates a waiting time TA until a time T7 comes, and transmits it as a time data TD to a timer setting circuit 32.
