Title: Method for evaluating haze of molding material
Inventor: ARATA MURAO
IPC: G01N19/04
Filed: 1982-10-15
Abstract: PURPOSE:To measure the haze of a molding material within a short time, by a method wherein the cavity of a mold is imperfectly filled with a material to form a molded product with haze while molding is performed under a perfect filling condition and the number of times required in eliminating haze are measured. CONSTITUTION:At first, the cavity of a mold is filled with a molding material in a filling degree of about 2/3 and, in this state, by performing about 50 times of moldings, volatile components in the molding material is adhered to the inner surface of the cavity to generate haze. Subsequently, the mold is allowed to stand for 2hr in a closed state and, thereafter, said cavity is perfectly filled with the molding material to perform molding. The haze on the inner surface of the cavity is transferred to the outer surface of the molded product but the number of molding times for eliminating the haze are measured. By this method, the haze generating degree of the molding material can be determined.

Title: Step motor driver
Inventor: YAMASHITA MASAYUKI
IPC: H02P8/00
Filed: 1990-07-10
Abstract: PURPOSE:To prevent degradation of S/N of reproduction signal and shift of recording track position due to the shift of step motor by rotating and driving the step motor toward a predetermined position through a rotation stopping means when a counter-electromotive force is detected under a state where the step motor is stopped in the predetermined position. CONSTITUTION:A control circuit 10 provides a drive command to a step motor drive circuit 7 to rotate a step motor 3 and to move a magnetic head 2 through a moving mechanism 6. Upon shifting of the magnetic head 2 due to application of external vibration, when the magnetic head 2 is stopped at a predetermined track for reproduction and recording, counter-electromotive force is induced in each phase of the step motor 5 and it is detected by a counter-electromotive force detecting circuit 16 which then provides a detection signal to a control circuit 10. Consequently, the control circuit 10 provides a driving command to the step motor driving circuit 7 which moved a reference position detecting circuit 15 to a position for detecting a reference track position thus driving the step motor 5 to the original position, i.e., a predetermined position, and stopping the step motor in that position.

Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of image defects by placing a rotor at a position shifted in the original feed direction from the point set right above an image-reading position and therefore preventing even an injured transparent member from affecting the images. SOLUTION: A scraper sheet 20 serving as a transparent member is placed between the image-reading position R of an original board glass 19 and a Sonosheet original which passes the position R. Then the sheet 20 guides the fed original. A white roller 21 serving as a rotor makes the original adhere or come close to the sheet 20 and the glass 19 and also prevents an out-of-focus state of the original image. For this purpose, the roller 21 is placed at a position shifted in the original feed direction from the point, set right above the position R. Specifically, the roller 21 is shifted to the upstream side of the oriental feed direction from the point, set right above the position R.
