Title: Method for coating inner surface of pipe
Inventor: TAKADA MICHITOSHI
IPC: B05D3/00
Filed: 1985-05-16
Abstract: PURPOSE:To reduce the time of dehydration and curing of a latex emulsion by depositing the latex emulsion on the inner surface of a pipe, supplying water- absorptive powder into the pipe by air conveyance and depositing the powder on the deposited latex emulsion. CONSTITUTION:A latex emulsion is deposited on the inner surface of a pipe and the deposited latex emulsion is dehydrated to form a coated film. In this method for coating the inner surface of a pipe, the latex emulsion A is firstly deposited on the inner surface of the pipe and then water-absorptive powder B such as silica gel is supplied into the pipe 1 by air conveyance and deposited on the deposited latex emulsion A. The time of the dehydration and curing of the latex emulsion can be remarkably reduced by such a simple means and a coated film having sufficient strength can be formed.

Title: Polygon motor control circuit
Inventor: SAKAI YUKIO
IPC: H02P1/16
Filed: 1985-05-16
Abstract: PURPOSE:To prevent a motor from the generation of uneven rotation by providing the title circuit with an optical synchronous detector for detecting a laser beam and a circuit for controlling a motor driving voltage by dropping the voltage gradually down to the ordinary one after reaching the detecting signal of said detector to a prescribed period. CONSTITUTION:A laser beam from a laser beam source 16 is deflected by a rotary polygon mirror 11 to scan the surface of a photosensitive body 19 and a part of the laser beam is made incident upon an optically synchronous detector 18. At the start of a drivig motor 12, the maximum voltage Vmax of a variable power supply circuit 13 is applied. When a laser beam is projected from the laser beam source 16, a detecting signal having frequency proportional to the rotational frequency of the rotary polygon mirror 11 is obtained from the detector 18. Detecting that the period of the pulse reaches a prescribed value, a pulse period detecting circuit 21 drops the voltage of the circuit 13 down to the ordinary one. When the voltage of the circuit 13 is gradually dropped by an integrating circuit, the motor can be prevented from the generation of uneven rotation.

Title: Measuring device having plural measuring points connected via cable
Inventor: HOIKO HIABORUSUKII
IPC: F17D5/06
Filed: 1981-07-03
Abstract: A measuring cable with spaced measuring stations is laid. The measuring stations each have a sensor whose electrical conductivity depends on an ambient variable such as temperatures light etc., each sensor is provided with a control arrangement which, due to a transmitted signal from a control center, connects its sensor to a constant current source and returns a signal indicative of any voltage change dependent on the variable ambient which signal is measured by the control center. The measuring cable is divided into sections each having a selectable circuit which can be selected individually by the control center. A clock pulse signal is transmitted to all measuring stations but is only active for the cable section which has been selected. In this manner, the cable section can be chosen as desired, the time required for the control center to have access to certain measuring stations is shortened and semiconductor switches can be used because measurements are only made in the steady state.
