Title: Paller clearance detector for unmanned forklift
Inventor: HITOMI SHINICHI
IPC: B66F9/24
Filed: 1987-10-21
Abstract: PURPOSE: To prevent malfunctioning by judging pallet detection only when the off distance of an optical sensor during lowering a fork claw provided with an optical sensor for detecting a load placing pallet is not less than almost the half of pallet clearance width. CONSTITUTION: A fork claw 14 is elevatingly mounted to a truck body 10, and the fork claw 14 is provided with an optical sensor 16 for detecting a pallet 19 with a load 17 placed thereon. It is so set that the clearance width (lp ) of the pallet 19 is lp /2>=lg to the dimension (lg ) of the space or light nonreflecting part of the load 17. The fork claw 14 is lowered into a search lower limit position, and if the off period of the optical sensor 16 is lp /2 or more, it is detected as the clearance of the pallet 19, and if the off period of the optical sensor 16 is smaller than lp /2, pallet search is repeated. Accordingly, even if the load 17 partially has the light nonreflecting part or space, it is not judged as pallet detection so as to prevent malfunctioning.

Title: Bearing for body of rotation
Inventor: SONOI KENJI
IPC: F16C35/077
Filed: 1988-10-21
Abstract: PURPOSE:To obtain a long life motor which is contructed to be easy to assemble, disassemble, check, and repair, and eliminates wear in a ball bearing hole by fitting a deforming member made of a shape-memory alloy into the ball bearing hole in a bearing of a motor, etc. CONSTITUTION:A ball bearing 5 supporting the rotation of a rotor 2 is inserted into a bearing hole 7 of a end bracket 4. A ring A8 is laid on the bearing hole 7 and its outer periphery is fixed. When temperature is constant (during assembling), both the bearing hole 7 and a ring hole 9 are fitted onto the ball bearing 5 with clearance fit-tolerance relative to the outer diameter of the bearing. The ring 8 is made of a shape-memory alloy, and the ring hole 9 is set to contract when temperature is high (during operation). The ring hole 9 contracts as temperature rises during operation. A slit A10 of the ring hole 9 accelerates the contraction. As a result, clearance fit of an outer ring of the ball bearing 5 into the ring hole 9 becomes interference fit, and the outer ring of the ball bearing 5 is thus fixed.

Title: Head core of magnetic head
Inventor: OUCHI HIROBUMI
IPC: G11B5/60
Filed: 1988-10-21
Abstract: PURPOSE:To obtain the head which is easily workable and has high mechanical strength and low fraction defective by forming a magnetic core thin in the sliding part with a recording medium and thick in the other parts. CONSTITUTION:The magnetic core A is constituted of an R/W core 1, a center core 2 and an erasing core 3 and is formed as thin as 0.15mm in the sliding part a of the magnetic recording medium and as thick as 0.25mm in the other part b. Slides 6 which hold the magnetic core A from both sides is formed thick in the sliding parts and thin in the other parts. The thickness working of the magnetic core A is, therefore, required only in the sliding part (a) and since the working depth is shallow, the core can be exactly finished by a slicer, etc., in a short period of time. Working of the core is thus easy. The fraction defective of the failure is lowered to 3% if the thickness of the sliding part (a) is specified to 0.15mm and the thickness of the other parts (b) to 0.25mm the cost is thereby reduced.

Title: Automatic adjustment method and circuit apparatus for adjustment amplification factor
Inventor: KURZ ARTHUR
IPC: G05B13/02
Filed: 1987-10-22
Abstract: In a control loop for automatically adjusting variable-gain amplification, a sinusoidal signal with a frequency fo that is critical for the control loop is superimposed over a positioning parameter W. Two synchronous rectifiers S1 and S2 filter out the oscillation components of a control parameter x and of a control difference xd that contain frequency fo, and the components are compared in a comparator VL. A control and regulating circuit C continues to vary the variable-gain amplification at controls RG until the amplitudes of the oscillation components being compared in the comparator are equal. The variable-gain amplification is correct at that point. The variable-gain amplification can even be adjusted in a compact-disk player while the player is in operation.
