Patent JP-H01243599-A (JP)
Title: Semiconductor laser module
Inventor: KONISHI CHITAKA
IPC: G02B6/42
Filed: 1988-03-25
Abstract: PURPOSE:To superimpose with ease a subsignal on a main signal by changing the angle of Faraday rotation by controlling a DC magnetic field by use of a second Faraday rotator wound with a coil. CONSTITUTION:By controlling a DC current I flowing through a coil 9, a DC magnetic field H excited on the coil 9, i.e., a Faraday rotation angle theta is varied. Herein, since the plane of polarization of the light is rotated but the plane of polarization of a second analyzer 11 has been fixed, the light intensity incident upon an optical fiber 7 can be changed as a vector. Further, once the current, which is made to flow through the coil, is changed with the subsignal, the subsignal can be superimposed on a main signal.

Abstract: PURPOSE:To completely use up a paper web and to complete multicopying operation without stopping on the way by detecting the end of the paper web in the multicopying operation, finishing the copy of remaining number of sheets which are set and stopping the copying operation. CONSTITUTION:The detecting pulse of a photosensor PC 1 is inputted in a control circuit, and the end of the paper web is detected from the number of pulse or from a pulse period within a T time. When it is detected that the paper web is finished, the display LED 310 of an operation panel is lighted. At the same time, if multicopying is in operation, the copying operation is continued until the remains of sheets the number of which is set in plural are finished to be copied. When said operation is finished, the copying operation is stopped. Thus, copying operation which responds to the set number of sheets is guaranteed without fail. In this case, if a copying device is provided with duplex and synthetic copying function, stopping copying operation with a copying sheet left on an intermediate tray can be prevented.

Filed: 1994-03-16
Abstract: PURPOSE:To omit a soaping treatment step after dyeing cellulosic fibers with a reactive dye and not only save the time, energy or cost due to the omission of the step but also improve the utilization efficiency of the dye and reduce the coloring of waste water. CONSTITUTION:The characteristic of this method for exhaustion dyeing cellulosic fibers with a highly affinitive reactive dye having a structure in which copper can be coordinated comprises carrying out the exhaustion dyeing of the cellulosic fibers with the highly affinitive reactive dye having the structure in which the copper can be coordinated and then treating the dyed fibers with copper without performing soaping treatment. Furthermore, the characteristic of this method for post-treating the cellulosic fibers dyed by the exhaustion of the highly affinitive reactive dye having the structure in which the copper can be coordinated comprises treating the dyed cellulosic fibers with a treating liquid containing a copper salt or the copper salt and a fixing agent without performing the soaping treatment. Thereby, high fastness can be retained by the post-treatment with the copper and the color fastness to light is especially remarkably improved.

Abstract: PURPOSE:To improve radiation efficiency by removing phosphor film's part not closely facing an irradiated surface so that apertures are formed and sticking a reflective film on a fixed inner peripheral surface of a bulb. CONSTITUTION:A positive column and a phosphor film 12e inside a bulb 12a are excited to become luminous.

Title: Thermal transfer printer
Inventor: HIRANO SEIICHI
IPC: B41J17/38
Filed: 1987-03-25
Abstract: PURPOSE:To obtain a printing image with gloss or of matte according to the demand of user, by selecting the separation position of an ink film and recording paper at the release time of both of them at the interior of ink or the interface thereof. CONSTITUTION:The positioning lever 11 pivotally supported at a fulcrum 12 and revolving in the direction by an arrow C or D by a drive means is engaged with the pin 10 of a lever 11 and the pressing position of a guide roller 6, that is, the release position of an ink film 21 and recording paper 22 changes by the revolution of the lever 11. When the angle formed by E, F in case the distance from E to F is remote is set to theta1 while the angle when the both are near is set to theta2, theta1>theta2 holds. When the angle is theta1, since the separation position of the ink film and the recording paper becomes the interface of ink, the surface 26-a of the transferred ink becomes relatively smooth and a printing image is glossy. When the angle is theta2, the ink film and recording paper are torn off in the ink and the surface 26-b of the transferred ink becomes a broken surface and, therefore, light is irregularly reflected from said surface to make an image matte.

Filed: 1982-04-30
Abstract: PURPOSE:To perform quick and accurate focusing, by setting the distance between a lens and an image pickup surface within an allowable range which is decided by the incident light and the depth of field, and reducing the working range for focusing as less as possible. CONSTITUTION:An incident light volume detector 10 produces a signal which shows the incident light volume through a lens 1. An aperture value detector 11 and a focal distance detector 12 produce digital signals which show the aperture value and the focal distance respectively. These signals are supplied to an arithmetic circuit 13 to produce a signal which shows a shift extent of the lens corresponding to the depth of field. These signals are supplied to a lens shift range setting circuit 14 to produce a signal which shows a boundary of the allowable range for the lens shift. This signal is supplied to a comparator 16 to be compared with a lens position signal. If the position of the lens 1 is outside the allowance range, an output signal is produced at the circuit 16 to control a motor driving signal processing circuit 17.

Title: Selection type delivery pump
Inventor: ISHII FUMIO
IPC: F04D13/00
Filed: 1987-03-25
Abstract: PURPOSE:To enable the air inside a casing to be securely released, by boring an air vent hole communicating with a liquid introducing passage on the inner wall of the casing. CONSTITUTION:When an impeller 40 is turned in the counterclockwise direction, the pressure in a valve chamber 46 becomes negative, while the pressure in a valve chamber 47 becomes positive. Thereby, valve bodies 54, 55 move to the left, so that the valve body 54 opens a suction port 50 and closes a discharge port 52, and the valve body 55 closes a suction port 51 and opens a discharge port 53. Accordingly, liquid flows from a liquid introducing passage 49, through the suction port 50, the valve chamber 46, a working passage 44, and into the valve chamber 47, and from the discharge port 53 it is delivered to necessary places. When the impeller 40 is turned in the clockwise direction, liquid is inversely sent out from the discharge port 52 to the other necessary places. In this case, the air inside a housing 16 is released through an air vent hole 63 and the liquid introducing passage 49 into an external tank 60. Thus, air does not remain inside the housing 16, and the function of the pump can be developed at its maximum.

Title: Monitor signal transmission system of digital transmission system
Inventor: FUJIOKA FUMIO
IPC: H04L25/02
Filed: 1984-04-10
Abstract: PURPOSE:To perform data transmission with high quality by generating the digitized pattern signal of the band signal of a main signal as a monitor signal by a transmitting device, and detecting the pattern signal in distincting from the main signal and also outputting the main signal through an LPF by a receiving device. CONSTITUTION:The transmitting device 1 generates the digitized pattern signal of an out-band signal as the monitor signal by a pattern generating circuit 14. This pattern signal is sent out by a switching and sending circuit 15 at optional timing as a substitute for encoded pulses of the main signal. The receiving device 3, on the other hand, leads a pulse signal arriving through a communication circuit 2 to a D/A converting circuit 31 and a pattern detecting circuit 33. This pattern signal is compared by the circuit 33 with a specific reference pattern and detected and a signal line driving circuit 34 operates with the detection output to output the pattern signal. At this time, the pattern signal is converted by the circuit 31 into an analog signal, which is cut off the LPF32 and not outputted to a receiving terminal, so that only the main signal is extracted without any deterioration in S/N ratio.
