Title: Manufacture of solenoid coupler
Inventor: SAKAI KUNIHITO
IPC: F16D37/02
Filed: 1989-08-03
Abstract: PURPOSE:To shorten the manufacturing process and reduce the cost of a solenoid coupler by supporting a solenoid coil in a groove of a magnetic member via holders, heating them, placing them in a forming mold, pouring epoxy resin, and hardening it. CONSTITUTION:A solenoid coil 1 with U-shaped holders 7 snapping on several points of the coil is placed in the center of a groove in a magnetic member 6a. The assembly is heated to about 150 deg.C and placed in a forming mold separately heated. Gap in a yoke 6 is filled with liquid state epoxy resin 10 poured from a runner 8a.

Title: Detecting device of rotation
Inventor: SATAKE ICHIRO
IPC: G01D5/30
Filed: 1990-07-31
Abstract: PURPOSE:To reduce a current consumed by a light-emitting element and to enable measurement of the amount of rotation of a rotary plate by making the light-emitting element emit a light intermittently by a pulse signal. CONSTITUTION:A light-emitting element driver 3, which is driven intermittently by a control pulse signal, makes a current flow from a power source 5 to a light-emitting element 2 and makes the element 2 emit a light intermittently. An output light signal from the element 2 is passed through a transmitting slit in a rotary disk and applied to a light-sensing element 6. An output signals of the element 6 by this applied light is a burst-shaped pulse signal. A synchronous detector 9 turns the pulse signal into a rectangular wave by a delay circuit 8, and a rotation amount detector 10 counts the leading or trailing edge of the rectangular wave from the detector 9 and thereby measures the amount of rotation of the rotary disk 1. By executing measurement by making the light-emitting element emit the light intermittently, in this way, the amount of rotation of the rotary disk can be measured with small consumption of power.
