Title: Optical device using optical fiber and adjustable in quantity of light
Inventor: NAGASAWA KIYOTO
IPC: G02B6/00
Filed: 1980-07-21
Abstract: PURPOSE:To improve the quality of copying by stabilizing the quantity of exposure by making the quantity of light, transmitting an optical fiber, adjustable by an optical light-quantity adjusting mechanism. CONSTITUTION:Irradiation light from a light source lamp 1 strikes the end surface of an optical fiber 9 facing to the hole 8a of a reflecting umbrella 8 and travels in the fiber to enter an optical adjusting mechanism 10. As the screw 12 of the mechanism 10 is turned, a diaphragm whose opening amount is fixed moves as shown by an arrow so that a prescribed quantity of light is inputted to a photodetecting element PD. Its output is passed through an operational amplifier T1 equipped with a negative feedback circuit consisting of a volume control VR and a resistance Rf and then compared with a reference voltage S by an operational amplifier T2 to adjust the quantity of light emitted from a light source 8 through a control circuit 2 and a stabilizer 3, thereby holding the illuminance of an original setting surface 4 constant. Thus, the quantity of exposure is stabilized and the quality of copying is improved.

Title: Paper position detecting mechanism for serial printer
Inventor: FUJII SHUJI
IPC: B41J13/00
Filed: 1985-05-10
Abstract: PURPOSE:To prevent a printing head and a platen from being damaged and contrive a reduction in cost, by a system wherein a reflection-type photosensor is provided on a carrier to monitor the position and the width of a paper, and the sensor is used as a paper sensor and as a home sensor. CONSTITUTION:The reflection-type photosensor 1 is mounted on the carrier 3 together with a printing head 2, and is reciprocated in the line direction. Prior to starting printing, the carrier 3 is returned until reaching the position of a left-end reflector 4, and the physical position of the carrier and a logical position controlled by a controlling circuit are synchronized with each other by a reading signal from the sensor 1. Then, the carrier 3 is moved rightward, the positions of the right and left ends of the paper are detected through light reflected from the printing paper, and the detected positions are compared with the left end of printing position (= left margin position) and the right end of printing position ( = right margin position) given by a host device. When both the position of the paper and the width of the paper are proper, a printing operation is started. Each time one line is printed, the carrier 3 is returned leftward until the left end of the paper is detected, whereby the position of the left end of the paper is checked.

Title: Optical modulator
Inventor: KAKIMOTO SHOICHI
IPC: H01S5/00
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To match the operating voltage of a refractive index compensator part and the power supply voltage of an optical modulator part by suppressing chirping while utilizing the effect of changing a refractive index with the injection of a carrier. SOLUTION: A laser beam generated by a semiconductor laser part 201 is made incident to a second multiple quantum well(MQW) layer 102 of an optical modulator part 202 and chirping is applied by optical modulation and a change in the refractive index of the second MQW layer 102 for 0.001 (mean value). This laser beam, to which the optical modulation and chirping is applied, is made incident to a guide layer 5 of a refractive index compensator 203 and by changing the refractive index of the guide layer 5 for -0.001 (mean value) because of a plasma effect, chirping is canceled. Thus, the operating voltage of the refractive index compensator part 203 can match the power supply voltage of the optical modulator part 202. Besides, the refractive index compensator part 203 can be operated at high speed.

Title: Engine operated by hot water
Inventor: NISHIOKA ISHIO
IPC: F03G4/00
Filed: 1986-05-01
Abstract: PURPOSE:To effectively utilize hot water so as to obtain the power source for a mining device by utilizing hot water which gushes out of a not water deposit to lift up and drop down a buoyancy tank while lifting up and dropping down a weight, and driving a generator accompanying the lifting up and dropping down of said weight via a chain. CONSTITUTION:A buoyancy tank 3 obtains buoyancy when the inside is filled with hot water and carries out a rising motion. When the buoyancy tank 3 comes close to the completion of rising, the top of a freely moving shaft 15 is brought into contact with an upper stopper 16 while a vent valve closing member 17 is stopped by a long circle ring 18. Then, after a valve restricting member 20 is moved in the direction of projecting out within a valve restricting guide structure 19, the valve restricting member 20 is pulled by a tension spring 22, causing the vent valve closing member 17 to be lowered inside the long circle ring 18. As a result, the vent valve 14 is fully opened and hot water inside the buoyancy tank 3 is discharged out causing the buoyancy tank 3 to lose its buoyancy. Accordingly, the buoyancy tank 3 is lowered by an up-down moving weight 13 via a chain 8, while a generator 11 is driven by the rotation of a chain wheel 9.

Filed: 1986-04-30
Abstract: PURPOSE:To read an original with a high resolution by providing lens sheets, which have focusing functions corresponding to picture elements in the main scanning direction, between the surface of the original and a photoelectric transducer array. CONSTITUTION:Since lens sheets 16 and 17 having focusing functions corresponding to picture elements at least in the main scanning direction are arranged between the surface of an original l and a photoelectric transducer array 8, the original is well read though the interval between the surface of the original 1 and that of the photoelectric transducer array 8 is made longer than the pitch of photoelectric transducers. An interference filter 18 where the transmission wavelength band is changed in accordance with the angle of incidence is interposed between the surface of the original 1 and the photoelectric transducer array 8, and the spectral transmittance characteristic of the interference filter and the spectral distribution characteristic of a light source 2 which illuminates the surface of the original 1 are properly selected to reflect the light, which has a wide angle of incidence, of the reflected light from the surface of the original 1 and this reflected light is prevented from being made incident on the photoelectric transducer array. Thus, the crosstalk is suppressed to read the original with a high resolution.
