Filed: 1989-12-15
Abstract: PURPOSE:To reduce the distortion of an output signal wave caused by the VBE-IE characteristic of a transistor by returning the increased/decreased part of an emitter current to flowing to an emitter follower circuit, which executes the impedance conversion of the output signal wave, to the emitter. CONSTITUTION:The emitter of a transistor Q1 is connected to constant current sources I2 and I3 and the collector of the transistor Q1 is connected to the collector and base side of a transistor Q2 on the reference side of a constant current mirror circuit 1 composed of transistors Q2 and Q3. Then, the collector side of the transistor Q3 on the output side of this constant current mirror circuit 1 is connected to the emitter of the transistor Q1. Namely, the increased/ decreased part of the emitter current to flow to the emitter follower circuit is returned to the emitter. Thus, the distortion of the output signal wave caused by the VBE-IE characteristic of the transistor can be reduced.

Filed: 1988-12-23
Abstract: PURPOSE:To expand the stable operating area of the circuit by providing a dummy circuit comprising a pseudo phase comparator and a loop filter, and a subtraction means, to cancel a non-signal component of the phase comparator due to power voltage fluctuation or the like. CONSTITUTION:Same circuit components in a power voltage fluctuation characteristic and a temperature fluctuation characteristic as those of a phase comparator 3 and a loop filter 4 are used for a pseudo phase comparator 92 and a loop filter 93 being components of a dummy circuit 9. Moreover, an input signal 91 having a frequency the same as or larger than that of an input signal 1 is inputted by taking the smoothness into consideration after passing through the filter 93, and the output signal having the same center frequency as that of the output of the comparator 3 is obtained. Then the output signal of the circuit 9 is subtracted from the output signal of the filter 4 to cancel the non- signal component because nearly the same non-signal component is superimposed on the output signal of the circuit 9 even if the non-signal component due to power voltage fluctuation or the like is superimposed on the output of the comparator 3. Thus, the stable operating area of the circuit is expanded.

The horn has an elliptic opening and transmits a far beam in the direction of narrow width. The shape of the opening is made as that of the detection area in the sensor B and a continuous wave transmitted from an ultrasonic oscillator 8 is transmitted in a direction which is a purpose. Then, the reflected wave of a human body moving in the detection area is receives. When the outputs of the both sensors are generated, it is decided that there is an object and a detection output is given. Thus, the missing warning or erroneous warning, which is the feature of the composite burglar sensor, can be decreased.

Title: Image forming device
Inventor: HORIGUCHI SHIGERU
IPC: G03G15/00
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent a malfunction caused by deflection caused by loaded paper sheets without increasing the volume to improve strength by providing a bending part by bending a part of a paper discharge tray upward. SOLUTION: When a large quantity of paper sheets are loaded on an inner tray 7 by continuous paper discharge, the inner tray 7 starts to deflect by weight of the paper sherts, and a part of a bending part 71 is displaced most downward. However, since the bending part 71 is bent upward by an angle θ, a corner part 77 is not displaced downward more than a plane composed of a plane- shaped part forming a great part of the inner tray 7, and the loaded paper sheets do not slide down outside. It can be easily taken out since the paper sheets extending to a cutout part 72 can be gripped when taking out a loaded paper sheet bundle.

Title: Laser printer
Inventor: HIRASAWA KEN
IPC: H04N1/04
Filed: 1988-12-27
Abstract: PURPOSE:To determine a position for starting recording an image on paper correctly by setting a time for starting a scan in the subscan direction of a laser beam in accordance with the amount of displacement detected by a subscan direction displacement detecting device. CONSTITUTION:A laser beam is projected to the surface of a photosensitive element 41 for scanning using a laser beam scan device 42. At the same time, the photosensitive element 41 is moved in a subscan direction by a photosensitive element moving device 43. Then the amount of displacement of the laser beam in the subscan direction is detected by a subscan direction displacement detecting device 44. Next time for starting the subscan is adjusted by a device for setting time for starting the subscan 45 in accordance with the detected displacement data. Therefore, if the laser beam is projected in the subscan direction due to any misalignment of laser beam from a laser generating source such as a semiconductor laser or an optical system, such misalignment is corrected. Thus it is possible to determine a correct position for starting the recording of an image on paper.
