Title: Rotary head device
Inventor: SASAYA TAKUJI
IPC: G11B15/61
Filed: 1990-02-02
Abstract: PURPOSE:To reduce the number of impact errors by arranging an air blowing means at least on the outlet part of a rotary head drum and safely floating a tape from a rotary head. CONSTITUTION:The air blowing means 16, 17 are arranged on the inlet 10 and outlet 11 of the rotary head drum 5 and high pressure air is fed from an air compressor 18 and blown out from blowing outlets 21, 22. The blown air is blown out from a gap 23 between a fixed drum 1 and a rotary drum 2 in the drum 5 to the outside in the radius direction. Thereby, a helically traveling magnetic tape can be stably floated from the rotary head 3. Thereby, the tapping phenomenon of the tape 8 due to the head 3 on the inlet 10 and the outlet 11 is reduced and the oscillation of the tape 8 is reduced, reducing the impact error of a reproduced output. Consequently, a beautiful reproduced image free from distortion or color shade is obtained.

Title: Conveyer
Inventor: ABE YOICHI
IPC: G11B23/023
Filed: 1985-02-12
Abstract: PURPOSE:To ensure degree of freedom of an attraction head and to prevent the attraction surface from tilting in a conveying system for conveying cartridges and the like from a depot by retaining the attraction head through springs to a retention mechanism. CONSTITUTION:An attraction head 2 is retained through restraining springs 6 and 7 to a retainer 3. With this configuration, the restraining springs 6 and 7 maintains the head surface facing the cartridge vertical when the attraction head is free so that head surface is not tilted relative to the cartridge surface. When taking out the cartridge, the other ends of the restraining springs 6 and 7 travel through guiding holes. Consequently, the degree of freedom is allowed and the head surface naturally aligns with the cartridge surface due to the deflection of the springs 6 and 7 even when the contact surfaces of the head 2 and the cartridge are not completely parallel. Thus, the degree of freedom is allowed to the head and non-parallelism of the head surface relative to the cartridge surface is prevented.

Title: Housing structure for hand-held type information processor
Inventor: SAITO TAKEO
IPC: G06F1/16
Filed: 1986-02-06
Abstract: PURPOSE:To prevent an unexpected injury by unfacilitating as much as possible the disassembly of a housing at the user side. CONSTITUTION:The case members that form an outer surface, i.e., a lower case 10, an upper case 20, a case cover 30 and a match plate 4 are connected intensively at hinge structure parts 5 and 5 to be formed into a monolithic structure. The internal circumferential surface of the cover 30 turns while a holder member 31 of the cover 30 produces the even contact friction with a ling-shaped friction member 6b and can stop at a prescribed opening angle. Thus a flat display 3 can be set an easy-to-see angle to an operator. Furthermore the frictional force of a fixed level is secured for a long period of time since the member 6b is inserted in a suppressed state. When a device thus assembled is disassembled, a hinge shaft 6 pressed into a main body must be pushed out to both sides and pulled out by means of a special tool.

Title: Waveform formatter circuit
Inventor: SUGIMURA AKIO
IPC: H03K5/156
Filed: 1989-02-03
Abstract: PURPOSE:To obtain a signal with short pulse width without being affected by the operating minimum pulse width of an RS flip-flop by directly generating the rise of a pulse with a first clock edge signal and the fall of the pulse with a second clock edge signal. CONSTITUTION:A gate 24 is closed by setting an NRZ signal to be added on the gate 24 at,'LOW', and a clock edge signal 2 whose timing is adjusted inputted from a delay element 22 is prevented from passing. Therefore, no D-FF 25 is operated, and only a D-FF 23 is operated by pattern data added from a memory 3 and a clock edge signal 1 added via a delay element 21. Since the D-FF 23 outputs the pattern data added on a terminal D at the leading edge of the clock edge signal 1, the NRZ signal can be obtained from the terminal Q of the D-FF 23. Thereby, it is possible to secure the pulse width of an output signal as a preset value as designed, and to obtain the signal with pulse width narrower than conventional one.
