Inventor: FUKAZAWA MAKOTO
IPC: H05K3/40
Filed: 1990-06-20
Abstract: PURPOSE:To make a press mold comparatively small and enhance the accuracy of the external shape of a lead-out part where a high accuracy is required, by a method wherein the external shape of the whole printed-wiring board is cut out and thereafter, the lead--out part only of the board is subjected to press working. CONSTITUTION:A printed-wiring board 10' is cut out from an blank plate 18. After that, a lead-out part 12 only of the pressed board 10' is subjected to press working in a state that guide members are respectively inserted in guide holes 14 using a mold to correspond to the form of a normal lead-out part and lug parts 12a and 12b and the like are eliminated. In such a way, a printed- wiring board 10 with the part 12, whose external shape is high in accuracy, is obtained.

Title: Picture photographing device
Inventor: HARA HIROSHI
IPC: G03B42/02
Filed: 1984-07-31
Abstract: PURPOSE:To reduce the idle time of an automatic developing device and to attain parallel photographing recording by moving exposing stages in the approximately vertical direction to find out respective exposing positions and then moving them in the approximately horizontal direction so as to move them to waiting positions. CONSTITUTION:On the waiting positions of exposing stages 7B-7D corresponding to respective feed belt devices 18A-18D, a photographing photosensitive sheet 12 is shifted from supply magagines 14B, 14C to the exposing stages 7B- 7D by the carrying motion of the feed belt devices 18B-18D. At the end of the photographing, the photographing can be restarted only by extracting the photographed photosensitive sheet 12, moving the exposing stage 7A to its waiting position and then moving another exposing stage 7B, 7C or 7D to the photographing position instead of the stage 7A. Consequently, frame recording can be attained independently of the charging/discharging time of the photosensitive sheet 12 and the working efficiency of an expensive computer motography device or the like can be improved.

Title: Tester for life of travelling-wave tube
Inventor: MITA OSAHISA
IPC: G01R31/24
Filed: 1981-10-12
Abstract: PURPOSE:To estimate the life of a travelling-wave tube by measuring a small signal gain of the tube when a high frequency input power thereto is lowered by about 20dB at a desired time to detect the tendency to deterioration in the tube for a relatively short time. CONSTITUTION:A signal generated with a signal generator 4 is introduced into a travelling-wave tube 1 to be measured by way of a rotary switch 5 and a high frequency line 3. The high frequency signal amplified by the tube 1 is measured with a high frequency power metal 6 and read with a controller 7. When moving from the condition as indicated by the solid line at the rotary switch 5 where the tube 1 is driven by a saturated output to the condition as indicated by the broken line at the controller 7, the signal from the signal generator 4 is damped by about 20dB with an attenuator 8 and becomes a small signal. The time-based change 10 in the gain of the small signal is measured based on the ratio between the small signal and the input power. Thus, the tendency to deteriration in the travelling-wave tube 1 can be detected quickly depending on the time-based change 9 in the saturated output thereby enabling the estimation of the life of a sample tube.

Title: Shot peening
Inventor: AIHARA HIDEO
IPC: B24C9/00
Filed: 1984-07-31
Abstract: PURPOSE:To suppress temperature rise on the surface of work thus to increase the surface compression residual stress effective for improving the fatigue strength of work by injecting shot grains toward the work while at the sametime blowing the cooling air continuously to the surface of the work. CONSTITUTION:An impeller type shot peening machine 1 will rotate continuously to inject shot grains 9 continuously through a slit 2 toward a rotating work 5. Upon collision of the shot grains 9 against the surface of work 5, the temperature on the surface of the work 5 will increase to lower the compressive residual stress near the surface of the work 5. Here, cooling air is blown continuously through the nozzle 8 of cooling machin 6 toward the surface of the work 5 thus to cool the surface of work 5 immediately. Consequently, lowering of the residual stress is suppressed to increase the surface compressive residual stress effective for the improvement of fatigue strength resulting in improvement of the fatigue strength when compared with conventional one.

Title: Electromagnetic flow meter
Inventor: SUZUKI ETSUMI
IPC: G01F1/58
Filed: 1982-09-16
Abstract: PURPOSE:To suppress the generation of leaked magnetic flux of an energizing coil, and to reduce a rise time of an energizing current, by providing a leaked magnetic flux suppressing means of the energizing coil, which is provided between a magnetic pole and a feedback magnetic path body, and is constituted of a nonmagnetic conductive material for surrounding a part of the outside circumference of the energizing coil without forming a closed circuit for surrounding the whole outside circumference of the energizing coil. CONSTITUTION:A block 7 for suppressing a leaked magnetic flux phiL of an energizing coil 4 is provided between a magnetic pole 3 and a feedback magnetic path body 6. The block 7 is constituted of a nonmagnetic and conductive material and surrounds the greater part of the outside circumference of the energizing coil 4, but does not form a closed circuit for surrounding the whole outside circumference of the energizing coil because it has a cut part 8. The suppressing body 7 is cut by at least one piece so that the closed circuit running along the outside circumference of the energizing coil 4 is not constituted, therefore, it has no effect for reducing a main magnetic flux phiM. That is to say, since it can reduce an hourly variation of the main magnetic flux phiM in a sampling time ts, it can reduce an electromagnetic induced noise containing in a signal fetched from an electrode 5.

When the rod diameters and bore diameters of the post and stroke detecting sub-cylinders 17, 29 are same, the strokes of both cylinders correspond to 1:1. At the time of the correction of the origin, the cylinders 17, 29 are allowed to fall and, when a current is supplied to a solenoid S5 in the vicinity of the completion of the falling process, the rod is pushed by the liquid pressure cross-sectional area difference of the sub-cylinder 29 to reach a stroke end and the working fluid is supplied to the rod of the post cylinder 17 to allow the rod to reach the falling end of the cylinder to correct the origin.

IPC: B62M9/08
Filed: 1990-06-20
Abstract: PURPOSE:To perform drive with the aid of a motor from a starting and to reduce a load on the motor during low rotation running by a method wherein a transmission mechanism interconnects the motor side and the drive wheel side only in a range of the given number of revolutions at which the maximum efficiency of the motor is provided. CONSTITUTION:When a motor 30 is started by means of a starter switch, not shown, a rotary shaft 50 is rotated. When the rotation speed of the motor is low, first and second centrifugal switches 78 and 85 are in a disengaged state, the drive force of the motor 30 is not transmitted to rear wheels 13, and a belt type continuously variable transmission 31 is in a racing state. When, from this state, an accel grip is rotated and the rotation speed of the motor 30 is increased, a centrifugal weight 73 is radially outwardly moved, the effective radius of a drive pulley 66 is increased, and the effective radius of a drive pulley 68 is decreased. This operation increases the rotation speed of a sleeve 75, and when the number of revolutions of the pulley 68 exceeds the set number of revolutions approximately equal to the number of revolutions at which the maximum efficiency of the motor is provided, the drive force of the motor 30 is transmitted to an input shaft 67 of a reduction gear.
