Title: Laser printer
Inventor: KAWAMURA NAOTO
IPC: H04N1/50
Filed: 1981-12-01
Abstract: PURPOSE:To obtain a titled laser printer at a low cost, by using in common a deflecting device for scanning laser light onto the surface of a photosensitive drum, by 2 or more beams of laser light, and decreasing the number of scanners. CONSTITUTION:Laser light from a laser unit, which is modulated by a picture signal and becomes parallel light by a collimator lens 11 is scanned by a rotary polyhedral mirror 22 rotated by a high speed motor 21. The scanned laser light is reflected 41, irradiated to a photosensitive drum 51, developed, and travels in the direction of a photosensitive drum 54, thereafter.

Patent JP-H1065280-A (JP)
Title: Mode detecting and controlling method for semiconductor laser
Inventor: CLAISSE PAUL
IPC: H01S5/042
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To judge a space mode by which a semiconductor laser operates, by monitoring the spontaneous emission to the drive current of the semiconductor laser, and distinguishing a point at which the rate of change for the spontaneous emission to the driving current changes suddenly in a range exceeding a threshold current. SOLUTION: A vertical cavity surface emission laser(VCSEL) 30 performs spontaneous emission, and this is detectable by a lateral surface detector 40. When the VCSEL30 operates while exceeding a threshold, the carrier density of an active region 32 is clamped effectively. The photoelectric current of the lateral surface detector 40 is measured as a function of the drive current to the VCSEL30. Since the spontaneous emission exceeding the threshold is proportional to the ratio of the fixed region of an activated layer/the unfixed region, the rate of change of the spontaneous emission, i.e. the gradient changes rapidly, on the occasion of a mode change. It then becomes possible to judge the change in a space mode by which the VCSEL30 operates, by monitoring the spontaneous emission from the VCSEL30.

Title: Feedforward non-linear distortion compensating amplifier
Inventor: YAMASHITA KAZUO
IPC: H04J1/00
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To obtain a feedforward non-linear distortion compensating amplifier(FF amplifier) in which unwanted spurious emission due to a pilot signal can be prevented from being generated, and the response time of each loop to the change in the operation condition can be shortened. SOLUTION: In this FF amplifier, a signal on a main line is fetched through an ALC (automatic level control) circuit 40 by a synchronism detector 36 as a reference signal, and the synchronism detection of a signal ERR fetched from a distortion compensating loop L2 is operated. It is possible to prevent the change of the offset voltage of a mixer in the synchronism detector 36 due to the change of an exciting level. The outputs of the synchronism detectors 36 and 38 can be used for the optimization control of corresponding loops L1 and L2. Thus, a pilot signal for a distortion detecting loop can be abandoned, and unnecessary spurious due to a pilot signal can be prevented from being generated. Also, the step-by-step optimization control under CPU control can be abandoned, and the response time of each loop can be shortened.

Title: Controller for missile
Inventor: SAKURAI KEIJI
IPC: G06F19/00
Filed: 1991-07-31
Abstract: PURPOSE:To control a missile so as to be capable of approaching a target linearly by a method wherein the generation of rotational speed, generated by the rotation of the missile, is prevented by a signal generated by an auxiliary guidance device, in the steering control of the missile. CONSTITUTION:A steering operating device 30 is constituted of an acceleration control filter 31, a subtractor 32, a rate control filter 33, another subtractor 34, a phase compensating filter 35 and an auxiliary guidance device 36. The auxiliary guidance device 36 generates a signal for cancelling an effect (pw) generated by the rotation of a missile and transmits it to the subtractor 34. In this case, the auxiliary guidance device generates a signal gammas obtained by subtracting the product of the roll rate Ps of sensor output by an attack angle (alpha) from a yaw rate gammas from a sensor 6 and transmits it to the subtractor 34. By this method, the generation of a rotational speed, generated by the rotation of the missile, can be prevented, the effect of (pw) is cancelled whereby the missile can approach a target linearly even though the missile is being rotated.

IPC: B62D5/09
Filed: 1982-11-01
Abstract: PURPOSE:To feedback-control an amount of discharge of a metering pump in such a manner as to measure an input angle of a steering handle and a real steering angle of wheels, and obviate difference in these angles. CONSTITUTION:A rotational angle thetah of an input shaft 2 is detected by a handle steering angle sensor 3, while a rotational angle thetat of a wheel 13 is detected by a real steering angle sensor 22, and both the angles are inputted to CPU25. At this time, if there is created difference between the input value thetat and a target value theta't stored in a memory circuit 26 corresponding to the input value thetah, a correction motor 20 is driven so as to obviate the difference. A correction gear 19 of a differential gear mechanism 6 is rotated by rotation of the correction motor 20 to revolve a planet gear 17 and modifyingly rotate a sun gear 16. Thus, an amount of rotation of a metering pump 7 is corrected, and an amount of flow to be supplied to a power cylinder 10 is feedback-controlled.

Title: Product transporting system
Inventor: TAI AKIHITO
IPC: B65G1/00
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To detect the presence of a load on a deck by carrying a loading bed located on a product loading surface and crossing an optical axis through the product loading surface on a chain conveyor and also providing a light projection sensor on a ground side and a reflector on a loading bed side. SOLUTION: A reflector 53 is installed on the outer side surface of two right side vertical machines 33 through a necessary bracket. Also, the reflector 53 is set so that it is positioned slightly on the outer side of the pallet and slightly upper side of the product loading surface when a pallet is loaded on a product loading surface. When a loading bed 30 is located at the transfer position, light is projected to the inner side surface of a left-side side frame 4 in the direction that it directs to the reflector 53 so that the optical axis of a light projection sensor 54 crosses the product loading surface, and its reflected light is received by a light projection sensor 54.  Thus, when the loading bed 30 is located at the transfer position, light between the light projection sensor 54 and reflector 53 is shielded by a carrying load located on the product loading surface of the loading bed 30 so that the detection of load presence can be assured.

Abstract: PURPOSE: To uniformly wind a continuous paper sheet without causing the skew by rotatably providing a positioning plate on the side of the first core so as to lock on the si.de of the second core on an opened end side of a slit for making positioning and fixing possible. CONSTITUTION: Carrying rollers 5a, 5b, a platen 7 and a winding shaft 30 are rotated with the progress of printing, and a continuous paper sheet 3 is wound round a winding shaft 30. As the winding quantity of the continuous paper sheet 3 increases, a load acting on the second core 32 of the winding shaft 30 also increases. But a positioning plate 40 is locked on the side face on an opened end side of a slit 33 in the second core 32 by fitting of a positioning projection 39 provided on the second core 32 into a positioning hole 42 provided on the positioning plate 40, and the opened end side of the slit 33 in the second core 32 is thereby fixedly held. The deflection of the second core 32 being due to the load is therefore prevented, and the continuous paper sheet 3 is uniformly wound without causing the skew.
