Patent JP-H02103984-A (JP)
Title: Semiconductor-laser driving circuit
Inventor: OKUMURA YOSHIHIDE
IPC: H01S5/042
Filed: 1988-10-13
Abstract: PURPOSE:To make a bias current constant and to prevent the entering of the bias current into the light emitting region of laser by providing a diode between the output of a current source whose current is changed in correspondence with the characteristics of the laser and the output of a current source which supplies the bias current. CONSTITUTION:The sinking current of NPN transistor 7 for current switching is set at a value larger than the maximum output current of a laser driving current source 5. Thus, the current which is supplied to a semiconductor laser 4 from the current source 5 becomes always zero when the transistor in ON. The bias current for a laser 4 is a constant value which is imparted from a current source 6. Since a diode 12 is provided, the bias current is not associated with the operation of the transistor 7. Therefore, even if a laser driving current is changed in response to the change in temperature of the laser 4, the bias current becomes constant. In this way, entering of the bias current into the light emitting region of the laser can be prevented.

Abstract: PURPOSE:To obtain the subject resin, excellent in adhesion to various substrates and capable of providing films excellent in chemical and water resistance, etc., by introducing a preemulsified mixture liquid of water and a resin into a flow passage in a chamber under pressure and subjecting the mixture liquid to collision with a planar part or mutual collision under specific conditions. CONSTITUTION:Water and a resin to be emulsified are predispersed and mixed to provide a mixture liquid, which is then introduced under pressure into a flow passage in a chamber and subjected to collision with a planar part in the flow passage under a high pressure of preferably 100-10000kg/cm<2> or mutual collision in the flow passage under the high pressure. Thereby, the resin is emulsified. As a result, the objective water-dispersible type coating is obtained. Furthermore, alkyd resins, acrylic resins, polyester resins, epoxy(ester) resins and/or fluororesins are preferred as the resin to be emulsified.

Title: Transfer material carrying device
Inventor: SAITO TETSUO
IPC: G03G15/00
Filed: 1985-11-20
Abstract: PURPOSE:To prevent the degradation of images independently of the variance of rotation of a pair of fixing rolls by forming such space that a transfer material can be bent to a downstream side of a transfer part in the advance direction of the transfer material. CONSTITUTION:When the front end of the transfer material rushes to fixing rolls according as the transfer material advances, a damping action is applied to the transfer material to push back the transfer material right. The transfer material is slacked to the downstream side of a corner part S of a guide 3a by the essential left carrying force, the force of friction due to the guide 3a, and the detaining action due to existence of the corner part S as shown by a long and double short dash alternating line P2. Consequently, the transfer material in the transfer part is not displaced to prevent the occurrence of black stripes. Even if the speed of fixing rolls is raised and attraction acts upon the transfer material, it is absorbed by the existence of the slacked part, and therefore, the transfer material in the transfer part is not affected at all.

Abstract: PROBLEM TO BE SOLVED: To obtain a projection type display device which is capable of projecting distinct images by preventing the generation of ghost images. SOLUTION: The light source light emitted from a light source 1 is converted to S polarized light having the vibration direction in an S direction with respect to the polarized light separating section 3P of a polarization beam splitter 3 by a polarized light converter 2 and is made incident on the polarizing beam splitter 3. Part of the S polarized light made incident on the incident surface of such polarization beam splitter 3 is made incident on the ground part and V-groove part of the polarizing beam splitter 3 and is scattered therein. Part of such scattered light is made incident on the polarizing beam splitter 3 and is emitted from the polarizing beam splitter 3 by reflection, etc., by the polarized light separating section 3P, etc.  The scattered light is the S polarized light which is made incident on a polarizing plate 5 arranged between the exit surface of the polarization beam splitter 3 and a projection lens 6. This polarizing plate 5 is arranged in the optical axis in such a manner that the P polarized light transmits the plate and, therefore, the incident scattered light is absorbed by the polarizing plate 5. Consequently, the incident of the scattered light on the projection lens 6 is averted and the generation of the ghost image may be prevented.
