Title: Scanner
Inventor: TERAO KENJI
IPC: H04N1/04
Filed: 1990-03-06
Abstract: PURPOSE:To use one light source for both lighting the surface of an original and for the back light of a display (LCD) by providing a reflector to guide light emitted from the light source, which lights up the original, to the LCD. CONSTITUTION:The light emitted from a fluorescent lamp 15 lights up a reading point on the surface of an original 13 and this is read through a 'Selfoc(R)' lens array 16 by an image sensor 17. One part of dispersed light from the fluorescent lamp 15 is guided to the lower part of an LCD 12 by a shielding member 19 and further full reflected on a reflector 18 and the whole lower surface of the LCD is equally irradiated. Namely, since one part of the light from the fluorescent lamp 15 to light up the surface of the original 13 is reflected on the reflector 18, this light is guided to the lower surface of the LCD 12 and operated as the back light. Thus, the fluorescent lamp 15 can be used for lighting up the original 13 and the back light of the LCD 12.

Title: Acceleration sensor
Inventor: HANZAWA KEIJI
IPC: G01P15/125
Filed: 1993-03-16
Abstract: PURPOSE:To allow highly accurate detection by providing the electronic circuit of sensor with a response characteristic adjusting circuit. CONSTITUTION:A movable electrode 6 is subjected to the inertial force of acceleration to be detected and displaced thus varying the capacitance C1 between the electrode 6 and a fixed electrode 7 and the capacitance C2 between the electrode 6 and a fixed electrode 8. A capacitance detecting section 13 detects the difference DELTAC between the capacitances C1, C2 based on a rectangular AC voltage generated from a signal applying section 19 and the difference AC is converted into a voltage. After an acceleration signal is converted into a voltage signal Vo at the detecting section 13, the acceleration signal is shaped at a response adjusting section 15 to produce a voltage signal Vo'. The signal Vo' is then amplified at an amplifying section 14 and adjusted to produce a linear output voltage Vout proportional to the acceleration. This constitution produces a stabilized acceleration response waveform at low cost.

Title: Insulation of winding of rotary electric machine
Inventor: NAKAYAMA KAZUAKI
IPC: H02K3/38
Filed: 1978-05-12
Abstract: PURPOSE: To prevent cracks due to thermal stress, by attaching short fibers with a bonding agent to the end of a winding and molding the short fibers with a resin.  
     CONSTITUTION: A layer 7 is made on an insulator layer 2 on the end of the winding from the bonding agent having the same main constituent as the molding resin. The short fivers of polyester, glass or the like are uniformly attached to the bonding agent layer 7 by fluid painting, spraying or the like so that a short fiber layer 6 is formed. The whole end of the winding is then molded with the resin 5. Because the thermal stress due to the heating of the winding in operation is absorbed by the short fiber layer 6, the cracks are prevented. Since the fibers are short, they adhere well to a part of complicated form as well. Thus, the cracks are surely and economically prevented.

Abstract: PURPOSE:To make it possible to transfer a work from one spindle to the other spindle while rotating the spindles in a lathe having two spindles on the opposite sides on the same axis by adding speed deviation signals of the two spindles to a speed command of either of the spindles to correct the speed command of the spindle. CONSTITUTION:Servomotors 1, 2 used to rotate two spindles in a machine tool are rotated and controlled at a specified speed by a current command from speed control circuits 3, 4. When command speeds v1, v2 are given to the speed control circuits 3, 4 the speeds of the servomotors 1, 2 are detected respectively by speed detectors 5, 6, and the detected results are outputted as speed data to an adder 7, which calculates a deviation speed.
