Inventor: KIKUTANI SATOSHI
IPC: G11B15/665
Filed: 1986-11-05
Abstract: PURPOSE:To reduce the thickness of a device by transmitting the quantity of relative movement between 1st and 2nd housings by using plural rotary bodies which rotate while engaging one another in a plane parallel to the bottom surface of a tape cassette. CONSTITUTION:The 2nd housing part 23 is provided with movement quantity transmission racks 68a and 86b which engage spur gears 71 and 72 at prolongation positions in a direction perpendicular to the guide direction of the housing part guided by a housing part guide means and the spur gears 71 and 72 and movement quantity transmission racks 68a and 86b constitute a movement transmission means which transmits the quantity of movement between the 1st and the 2nd housings shown by an arrow 84 between the positions on the prolongation shown by an arrow 85. Consequently, when the housing rack 45 integrated with the 2nd housing part moves as shown by an arrow 84, the transmission rack 86a engaging the spur gear 71 equalizes the quantity of relative movement between the 1st and the 2nd housing parts shown by the arrow 85, and enables smooth relative movement without increasing a movement load owing to a difference in the quantity of movement between both sides.

Title: Inverter device
Inventor: KOJO TAKUYA
IPC: H05B41/282
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To improve the power factor of an inverter device and, at the same time, to obtain a slightly low high-frequency output voltage from the inverter device without using any transformer. SOLUTION: When the voltage of each capacitor is a single capacitor voltage in a steady state, the voltages of a first capacitor element 110 while the element 110 discharges, a second capacitor element 120 while the element 120 is charged, and a load circuit 200 respectively become one time, two times, and one time as high as their voltages. The instantaneous value of the voltage of rectified power 2 in a critical mode is three times as high as the single capacitor voltage and, when the instantaneous value becomes higher than the value, a charging mode is set. When the instantaneous value becomes lower, a discharge mode is set. Therefore, a relatively long feeding period can be obtained even when the capacitance of a smoothing capacitor is sufficiently large.  When charging is made in a steady state, the charging current has no peak, because the load circuit 200 works as an impedance element.

Title: Variable power image forming device
Inventor: KITAGAWA SHOICHI
IPC: G03B27/34
Filed: 1989-10-09
Abstract: PURPOSE:To greatly reduce the cost of the device by providing a cylindrical lens, whereby wide, collimated incident light in a scanning direction is narrowed in the width direction and is condensed at a focal point, half way along the optical path of the light reflected from a mirror. CONSTITUTION:As a variable power lens 21 is moved variably magnifying in a reduction direction P, the fourth mirror 22 is parallelly moved towards the variable lens 21, or as the variable power lens 21 is moved for variably magnifying in an enlargement direction Q, the fourth mirror 22 is moved away from the variable power lens 21. Collimated light reflected from the fourth mirror 22 is transmitted through the cylindrical lens 23; the optical axis of the light reflected from the fourth mirror 22 is turned towards the focal point of the cylindrical lens 23, that is, one point on the photosensitive body surface S, and it is made incident on the photosensitive body surface S; therefore, change in a latent image forming position is prevented. Since the need for an image-forming-direction-alteration setting means, whose structure is considerably complicated, for altering the angle of the mirror complicatedly can be eliminated, the cost of the variable power image forming device is greatly reduced.
