Title: Light source device and projection type display device
Inventor: FUKUHARA MOTOHIKO
IPC: G03B21/14
Filed: 1994-10-06
Abstract: PURPOSE: To improve the utilization efficiency of the quantity of light emitted from a light source and also to equalize the brightness distribution of the display screen of a projection type display by installing both a mirror having the light source arranged in one of focuses in a closed reflecting surface having the plural focuses and a rodlike light guiding body respectively in a light source device. CONSTITUTION: An ellipsoidal mirror 30 has a first focus 32 and a second focus 33, and has a light source 20 arranged therein in such a manner that the emission center of the light source 20 may be squared with the first focus 32. Moreover, a rodlike transparent body 40 has an incident end surface 42a formed by the end surface of its incident side disk 42 while having an exit end surface 43a formed by the end surface of its exit side disk 43. The end surface 42a is for the purpose of taking in light and has its center equalized to the position of the second focus 33 in the mirror 30.  A beam of light incident upon the end surface 42a can then be emitted entirely without any loss from the end surface 43a so as to heighten the operational efficiency of a light source device 10 to 70% of the quantity of light emitted from the light source 20 by approximately paralleling the beam of light emitted from the end surface 43a to a central axis 40a. The utilization efficiency of the quantity of light emitted from the light source 20 can consequently be improved, and the brightness distribution of the display screen of a projection type display can be equalized by forming the end surface 42a in such a manner that it may become slightly larger in area than the light source 20.

After iron dust is removed by a magnetic separator 3, the shredder dust is stored in a storage tank 13 and charged in a melting and solidifying-granulating device 4 by a conveyor. The granulating device 4 granulates fine strip dust A' and the shredder dust is separated into a route P or Q according to the state of the fine strip dust A' for processing. The strip dust A' is crushed into a finer state and made a half- molten or complete molten state by a friction heat. Granulated dust is injected through a nozzle and rapidly cooled and contracted and solidified in a grain- form state. Granulated dust (a) stored at a primary storage tank 6 is transported pneumatically from a service tank 7 to an air feeding device 8.  The dust is then blown in a blast furnace 12 through a blow-through pipe 10.

Title: Spring assembly
Inventor: INOUE NOBUHIKO
IPC: F16H57/023
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To provide the spring assembly excellent in twisting resistance by forming each elastic body out of a metallic leaf spring which is continuously bent into a bellows form, and arranging the leaf springs in a bellows form each along the circumferential direction of each circular plate. SOLUTION: The spring assembly has elastic bodies interposed between circular plates 2A and 2B mounted at equal intervals. Each metallic leaf spring 1 which is continuously bent into a bellows form, is used as an elastic body, and the metallic leaf springs in a bellows shape each are interposed between the circular plates 2A and 2B along its circumferential direction. By this constitution, even if each leaf spring 1 itself continuously bent into a bellows form, may buckle depending on the direction, when each leaf spring is interposed between the circular plates 2A and 2B along its circumferential direction, each individual leaf spring 1 is effectively prevented because of the synergism of the respective leaf springs 1 from buckling, as a whole, stiffness can thereby be obtained, which hardly buckles extremely.

Title: Vehicle suspension device
Inventor: WATANABE YOJI
IPC: B60G17/0185
Filed: 1990-09-14
Abstract: PURPOSE:To prevent the unprepared suspension of supply discharge control and to continue the supply discharge control of hydraulic working fluid even in the case where running on a rough road causes the failure of supply pressure by correcting downward fixed pressure to condition the suspension of supply discharge control when a vehicle running road is rough. CONSTITUTION:A pump 28 draws a hydraulic oil 32 from a reservoir tank 30, and forcedly feeds it to each of high pressure pipes 26F, 26R for a front and a rear wheel through a common high pressure pipe 26. In this case, when supply pressure becomes below a lower limit setting value (fixed pressure P1), an unload relief valve 70 is closed through a control unit, and the hydraulic oil is therefore accumulated in a main accumulator 40 to raise the pressure in the high pressure pipe 26. When the supply pressure becomes lower than the fixed pressure P1, an electromagnetic switching valve 48 is closed at a fixed pressure P2(P2<P1) to stop the supply discharge control, which ends at a fixed pressure P3(P3<P2). In the case where a vehicle running road is rough, the fixed pressure P2 to condition the suspension of the supply discharge control is corrected downward.

Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a recording apparatus which can accelerate to a predetermined velocity quickly in a simple constitution and control a carriage velocity with a small overshoot. SOLUTION: At a rise-time of a carriage of this portable printer, an output- selecting part 4544 selects a first fixed output part 4542 of a PID operation part 454 to send a control signal to a PWM generation part 455 to output to a CR motor a driving signal of a PMW system of a relatively high duty ratio. When the output-selecting part 4544 receives from an encoder cycle- measuring part 453 a signal reaching a switch velocity Vc set to a predetermined ratio of a print velocity Vp, the control signal is switched to be output from a second fixed output part 4543. When a carriage velocity further reaches a predetermined control start velocity Vs, the control signal is switched to be output from a PID output part 4541, whereby a PID control is stated. The carriage velocity that rises in a short time and is stable is obtained accordingly.
