Title: Magnetic recorder
Inventor: MATSUMURA KOICHI
IPC: G11B21/12
Filed: 1989-10-19
Abstract: PURPOSE:To prevent a failure caused by abutting a recording head against a magnetic recording medium when the medium is inserted by moving the recording head to a prescribed initial position with power from a backup power source when an external power source is dropped in voltage. CONSTITUTION:When the power is being supplied from the exterior, the backup power source 16 is on charge, and when a voltage drop of the external power source is detected by a detecting circuit 17, a motor 12 is driven by the power of the backup power source 16 to move the recording head 11 to a zero track position. Consequently, it is impossible that the recording head remains stopping in a position at the time of cutting off a system power source, so that the medium cannot be abutted against the recording head 11 when the medium is inserted into a prescribed housing part. By this method, such a failure as deformation of a gimbal plate and displacement of a zero track sensor, etc., can be eliminated.

IPC: G11B23/02
Filed: 1994-10-13
Abstract: PURPOSE: To prevent a side wall of a storage case from being easily distorted even when an external force acts to the storage case. CONSTITUTION: In a storage case 100, a free end part 14 of a side plate 12 vertically formed from a top plate 11 of a cover body is clamped by a side wall 33 of a case body and a fastening piece 41 vertically provided on a bottom plate 31 in the sate that the cover body is closed to be prevented from slipping off the outer peripheral edge part of the bottom plate 31. In this manner, such a deformation that the cover body comes close to the case body can be prevented even if an external force acts to the storage case 100.

Title: Power source circuit
Inventor: NORO MASAO
IPC: H02M3/337
Filed: 1991-09-25
Abstract: PURPOSE:To reduce a current flowing to a switching element and to prevent generation of heat in a power source circuit in which all switching operations are conducted by a zero voltage or a zero current by alternately utilizing current and voltage resonance operations. CONSTITUTION:A transformer has a primary winding 10 with a center tap. Two switching elements S1, S2 are connected in series between both ends of the winding 10. A DC power source 1 is connected to a point between the connecting point P of the elements S1, S2 and the center tap Q of the primary winding. The elements S1, S2 are alternately turned ON, OFF to perform a parallel resonance by a primary self-inductance L1 of a transformer and a capacitor C1 and to achieve a series resonance by leakage inductance L2 between primary and secondary windings and the capacitor C2. Thus, a zero- voltage ON, a zero-voltage OFF are realized. Since the switching is of a push- pull type, currents flowing to the elements S1, S2 are reduced by half as compared with a half-bridge type.

Filed: 1988-10-31
Abstract: PURPOSE:To maintain the length of chain suitable at all times by making a connecting shaft between an upper link and a lower link movable in response to changes in the degree of tension of a scrape-up chain to automatically adjust variations of the length of chain or elongation thereof which occur when a lifting frame goes up and down. CONSTITUTION:When a bucket 18 etc., is burried in settled sand due to abnormal accumulation thereof or settled sand is transferred to other settled sand area, a lifting frame 6 is lifted up as illustrated by chain lines. Each swivel link 4 is swiveled so as to be folded up as shown by chain lines, whereby changes in the length of a scrape-up chain 17 occur. However, an expansion rod 21 is caused to be forced into a cylinder or a shock absorber 20 in response to changes in the degree of tension of scrape-up chain 17, so that the length of chain 17 is automatically adjusted. In this manner, a chain wheel 10, together with a connecting shaft 5, is moved along an upper link 4a when the lifting frame 6 goes up or down, so that delicate changes in the length of scrape-up chain 17 can be compensated.

Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To safely connect and disconnect a sorter by miniaturizing a plate by adjusting and fixing a sheet guide part of an equipment main body by matching it with a sheet introduction part after installing the plate on the equipment main body free to adjust and fixing the plate at a specified position by placing a caster on it. SOLUTION: A plate 25 is placed on a carpet on a comparatively extensive surface and fixed on a copying machine 21 by adjusting height at a slot part 25a without sinking it so deep as the copying machine 21. At this time, as there is a deviation between height of the copying machine 21 and height of a sorter 22, it is installed by adjusting a sheet guiding part 42 to match with a sheet introduction part 41 and adjusting a latch receiver plate 44 to match with a latch lever 43. That is, at the time of setting a device on a flexible floor material, height of the sheet guiding part 42 is adjusted by placing the sorter 22 after fixing the plate 25 by deciding its height position. Consequently, it is possible to easily set it even when setting height of an equipment main body and setting height of the sorter are different from each other.
