Title: Magnetic tape recording regenerator
Inventor: YOHANESU YOZEFU MARUCHINUSU SH
IPC: G11B15/10
Filed: 1981-11-16
Abstract: An apparatus for recording and/or reproducing signals on a magnetic tape is provided with two reel discs (97, 98; 160, 161), at least one magnetic head (17, 18; 165, 166) which is arranged on a head slide (19; 164, 194), a pressure roller (137; 180) arranged on a pivotable pressure-roller arm (135; 179) and which is movable against a capstan (96, 185), a central drive wheel (83; 157) which is rotatable in two directions and which, via normal-mode and fast-mode idler wheels (84, 169 and 91; 159 respectively) carries on pivotable arms, can drive the reel discs, and a pivotable switching lever (114, 176, 206) which is adapted to be coupled to the pressure-roller arm, the fast-mode idler arm and the normal-mode idler arm and to brake arms (104, 105; 171, 173). 
<??>Depending on the direction of rotation of the central drive wheel the fast-mode idler arm is pivoted from an inoperative position into a first or second operative position respectively. In a first position control means which are adjustable to two positions limit the pivotal movement of the switching lever to movement into a first, partly pivoted operating position. in which first position of the control means the fast-mode idler arm is uncoupled from the switching lever so that the fast-mode idler arm is pivoted. In the second position of the control means the switching lever is pivotable into a fully pivoted second operating position, the fast-mode idler arm then occupying the inoperative position through the coupling of the fastmode idler arm with the switching lever and the normal-mode idler arm being pivoted into the operative position. In both operating positions the switching lever is also coupled to the head slide.

Title: Ignition coil
Inventor: KAWAI KAZUHIDE
IPC: H01F38/12
Filed: 1989-07-14
Abstract: PURPOSE:To provide possibility of compatible use of a plug type head terminal and an M4 screw type head terminal without causing increase in the price by dimensioning specifically the gap between the periphery of a coil spring and the inside surface of a high voltage tower and a high voltage terminal and also the gap between element wires of the coil spring in a plane. CONSTITUTION:The gap between element wires of a coil spring 6 constituting a spiral part shall be smaller than 4mm. This coil spring 6 is formed with such a dia. that the gap between the inside surface of a cylindrical part 4a and the periphery of spring in a plane including said spiral part is smaller than 4mm. In an ignition coil 1, therefore, any gap larger than the outside dia. of an M4 screw type head terminal 5 can be eliminated in the plane including the spiral part of the foremost end of the spring 6. Also in a high voltage tower 3, accordingly, the head terminal 5 of an ignition plug 2 will never intrude into the gap between the periphery of the spring 6 and the inside surface of the cylindrical part 4a nor be inserted into the bore of the spring 6 when the coil 1 is fitted to the ignition plug 2 while fitted to a connection cap, and stable contact with the spring 6 is secured by pressing the spiral part of the spring 6.

Title: Optical information recording and reproducing device
Inventor: YOSHIZAWA TOSHIYASU
IPC: G11B7/00
Filed: 1983-09-30
Abstract: PURPOSE:To eliminate the crosstalk in a read mode and to improve the recording density by dividing a recording track into two parts to record bit trains of different depths to each divided track and reading these bit trains by the beams of different wavelengths. CONSTITUTION:The laser beams given from light sources 21 and 22 have different wavelengths lambda1 and lambda2 (lambda2=lambda1) and are put into a beam splitter 24 with a minute angle difference between their optical axes. Then both beams irradiate a medium 28 with a slight shift secured between positions of irradiation of both beams in the radius direction of the medium 28. In other words, the beams lambda1 and lambda2 irradiate bits 31 and 32 respectively. The depths d1 and d2 of these bits are proportional to the values of beams lambda1 and lambda2 respectively. At the same time the diameters of spots 33 and 34 are also proportional to beams lambda1 and lambda2 respectively. The beam lambda1 reads the bit 31 and a part of this beam also irradiates the bit 32. However the reflected light given from the bottom part of the bit 32 has a difference of phase by 2 radians owing to the relation between (d) and lambda and has no difference of optical intensity to receive no modulation of the bit 32. So is with the effect obtained by the bit 31 of the beam lambda2.

Title: Hot wire type air flowmeter
Inventor: MAKINO JUNICHI
IPC: F02D45/00
Filed: 1988-07-23
Abstract: PURPOSE:To improve response by returning a deformed balanced bridge circuit into an ordinary bridge circuit, and changing the connection to a differential amplifier. CONSTITUTION:A balanced type bridge is composed of resistors 1-3 and a heat resistor element 4 for detecting the flow rate of air. The balanced state of the bridge circuit is detected with an operation amplifier 5. For an operation amplifier 10, resistors 7 and 8 and a heat resistor element 9 for compensating temperature are provided. A voltage output V2 as a function of the flow rate of air becomes as follows: V2=R3R7V1/(R7+R8+Rc)(R2+R3)-R7V01/(R7+R8+ Rc)-V02. The effect term VTOFF of the offset voltage in this expression is as follows: VTOFF=R7V01/(R7+R8+Rc)+V02. When R1=10OMEGA, R2=9kOMEGA, R3=400OMEGA, R7=232OMEGA, R8=11OMEGA and Rc=20OMEGA, VTOFF=0.88V01+V02 is obtained. The effect of the offset can be made sufficiently small. Therefore, a hot wire type air flowmeter having a high response speed and excellent characteristics is obtained.
