Title: Toner density control system
Inventor: SHOJI MOTOHIRO
IPC: G03G15/08
Filed: 1989-07-10
Abstract: PURPOSE:To detect accurate toner density by detecting the optical density of an image carrier right before a toner image detected by a detecting means, and deciding whether or not toner supplementing operation is performed according to the optical density. CONSTITUTION:The optical density of the image carrier 19 right before the toner image detected by the detecting means 20 is detected and a control means 23 decides whether or not the toner supplementing operation is performed according to the optical density. Thus, the optical density is detected at the position right before the position where the optical density of the toner image is detected, i.e. at the position where the toner image is not formed and the detected optical density is used as a reference value to make a decision in consideration of ground staining. Further, the position right before the detection position is checked unless the ground staining is uniform on the image carrier 19 to places a background part and a toner image in nearly the same state and obtain the position where an eccentricity quantity is nearly equal. Consequently, the accurate toner density can be detected.

Title: Automatic signal level adjusting device for recording
Inventor: MURAKAMI SHOJI
IPC: G11B20/10
Filed: 1986-07-30
Abstract: PURPOSE:To keep the recording level at optimum condition by comparing a reproducing signal level with a reference value in response to a sampling command and attenuating a reproducing signal level of a PCM sound reproducer by a prescribed quantity when a reproducing signal level exceeds the reference value. CONSTITUTION:A sampling command S2 is fed to a comparator 74 and a switching signal generating circuit 76, the output of the circuit 76 is set initially to set the attenuation of an attenuator 68 to a minimum value. After a signal S3 through a buffer amplifier 66 is attenuated by the attenuator 68, is fed to the comparator 74 via an amplifier 62 and a buffer amplifier 72 and is compared with the reference level. When the output level of the amplifier 72 exceeds the reference level, an attenuation switching command S1 is fed to the switch circuit 70 from the circuit 76 to increase further the attenuation of the attenuator 68. Thus, the level of the amplifier 72 is lowered and fed to the comparator 74 and the processing is repeated. Thus, the maximum level of an output signal S4 is brought into almost prescribed value and the recording level is kept optimum.

Abstract: PROBLEM TO BE SOLVED: To measure with high sensitivity when measuring a semiconductor sample having a low specific resistance or using a short wavelength detecting electromagnetic wave by applying the detecting electromagnetic wave to the surface of a semiconductor wafer at a low incident angle near the critical angle. SOLUTION: An infrared semiconductor laser oscillator 1 emits an infrared light 16, a mirror 2 reflects it, a wavelength plate 3 adjusts so that the electric field vector is parallel to the incident plane, the light 16 passes through a prism 15 and glass stage 14 and is radiated on the back side of a semiconductor wafer 13 at an incident angle near the critical angle to the wafer surface, while a computer 8 adjusts the angle of a mirror 2 to determine the incident angle θ. Thus it is possible to measure with high sensitivity when measuring a semiconductor sample having a low specific resistance or using a short wavelength detecting electromagnetic wave.

Filed: 1980-12-18
Abstract: PURPOSE:To inhibit overcurrents by electrically detecting the condition of an induction motor and controlling currents by the signals when the motor reaches the maximum speed. CONSTITUTION:When a current command Iref high than currents corresponding to necessary secondary currents is given even after the induction motor IM reaches the maximum speed, the currents of the secondary currents or higher of the necessary motor flow through a rectifying device SR of an additional circuit and a current detector IDET.

Title: Impeller for centrifugal fan
Inventor: KIDA TAKUMI
IPC: F04D29/30
Filed: 1988-07-18
Abstract: PURPOSE:To prevent the separation of the air flow at the impeller negative pressure surface side near a main plate by projecting an impeller inlet side end part of the boundary part from a main plate of the impeller to the direction of the rotation of the impeller. CONSTITUTION:The air led into an impeller 6 from an inlet 5 through an orifice, to which the dynamic pressure and the static pressure are added by the work of a vane plate 7, are discharged to the out of the impeller 6. The vane inlet angle beta1 at a projection 7a to the direction of the rotation at the vane inlet side end part of the boundary part of a vane plate 7 from a main plate 8 is almost coincide with the air inflow angle near the main plate 8 which becomes small by the lowering of the inflow air current speed. Thereby, the inflow air near the main plate 8 flows along the vane plate 7, and the generation of separating of the flow at the vane plate 7 ventral side near the main plate 8 is eliminated.

Abstract: PURPOSE:To shorten an image processing time and to reduce the capacity of an image storage memory by converting image information from analog to digital into a binary signal and compressing binary-coded information of every picture properly. CONSTITUTION:A two-dimensional scanner 3 is moved by an XY two-axis robot 4 in a device which measure an image pattern on paper, etc., so as to cover the entire area on a body to be measured which is paper, etc., (obtained by photographing a flaw made in, for example, a manufacture process of metal).
