Title: Optical head
Inventor: KIYOMATSU SATOSHI
IPC: G02B17/00
Filed: 1993-03-16
Abstract: PURPOSE:To make an optical head small in size and light in weight, to decrease the loss of a light quantity and to obtain high stability by using the first reflection surface with a convex ellipsoidal shape of an objective lens and its second reflection surface with a concave paraboloidal shape. CONSTITUTION:A light beam transmitted from a semiconductor laser 11 is reflected by the first reflection surface 12 of an objective lens 14 and reaches a second reflection surface 13. The reflection surface 12 has an arbitrary convex- like ellipsoidal shape and the function for widening the radiation angle of the reflected light compared with the incident light. The reflection surface 13 has a concave-like paraboloidal shape, transforms the light beam from the reflection surface 12 to an almost parallel light beam and makes the beam incident on the objective lens 14. The light beam forms an image on a recording surface 15 as a light spot about 1mum in diameter by the light converging action of the lens 14. The lens 14 is composed of a micro-Fresnel lens made of a concentric diffraction grating and is formed as an integral structure directly on the substrate of the optical head or being in contact with it. Data are recorded or picked up on the recording surface 15 by means of the formed spot of the image.

Title: Image forming device
Inventor: KONUKI KAZUHIKO
IPC: G03G21/16
Filed: 1984-03-23
Abstract: PURPOSE:To enable simple changeover by attaching and detaching the cartridge of an image forming device to exchange said cartridge, selecting the mode for copying and changing over the process conditions to the conditions meeting the copying mode cooperatively with said selection. CONSTITUTION:A cartridge for copying a positive original image to a positive image is exchanged with a cartridge 13' having a developing device 17' for an N-P mode in the processing stage in the N-P mode for copying the negative original picture to the positive image. When the cartridge 13' is inserted into the device, a cam 52 lifts a turning light shielding plate 37 up to the position where said plate overlaps partly on a stationary light shielding plate 36 thereby closing the blank exposing path from a lamp toward the reflecting surface of a shutter 30. The plate 37 pushes further a changeover switch 40 to change over the same to the N-P mode side. When copying is executed in the copying part set in such a way, the light from the lamp is kept free from making blank exposing even if the shutter 30 exists in the solid line position as the plate 37 is held closed. Since the switch 40 is held on the N-P mode side, the polarity of the voltage impressed on an electrifier for transfer changes over and the quantity of the light from the light source of image exposing is so controlled as to meet the N-P mode.

IPC: F28B11/00
Filed: 1987-03-13
Abstract: PURPOSE:To enable superior controlling characteristics to be attained even in a low speed range by a method wherein a condensate recirculation valve 4 is forcedly and fully opened to increase the flow rate of condensate and the discharging pressure of a low pressure condensate pump is decreased. CONSTITUTION:Condensate accumulated in a condenser 1 is increased in its pressure by a low pressure condensate pump 2, a high pressure condensate pump 5 and a turbine driven water supplying pump 6 or an electric motor driven water supplying pump 7 and then fed to a stem generating unit 8. A condensate control unit 9 is operated such that a condensate flow rate adjusting meter 10 normally inputs a condensate flow rate signal from a condensate flow rate sensor 3, a control signal is converted by an electronuematic converter 11 from an electrical signal into an air signal to adjust the degree of opening of the condensate recirculation valve 4. However, when a changing-over signal 12 between the electric motor driven water supplying pump 7 and the turbine driven water supplying pump 6 is inputted, the condensate flow rate adjusting meter 10 may output a signal for fully opening and condensate recirculation valve 4. Then, correspondingly the flow rate of condensate is increased and a discharging output from a low pressure condensate pump 2 is decreased. A reduction in discharging pressure of the low pressure condensate pump 2 causes a suction pressure of the turbine driven water supplying pump 6 to be decreased and thereby the number of revolution of the turbine driven water supplying pump 6 is increased.
