Title: Dark field illuminating device
Inventor: OTAKI TATSURO
IPC: G02B21/10
Filed: 1988-10-05
Abstract: PURPOSE:To make a microscope compact and to obtain an inexpensive illumination for dark field with a simple constitution by providing an optical fiber in a ring tube shape along the circumferential direction of a path for illuminating. CONSTITUTION:The optical fiber 28 for illuminating a ring band is provided in the ring tube shape along the circumferential direction of the path 24 for illuminating surrounding an observation path 10 where an objective lens 5 is disposed. Light from a light source 27 provided on the outside of the path 24 for illuminating is supplied to the optical fiber 28 through an illuminating light induction part 20a as the illuminating light. As a result, it is unnecessary to provide a light shielding barrel which is provided in a conventional one so that the illuminating light does not advance into an observation optical system and the path for illuminating. Since the diameter of the screw of a lens main body can be made smaller, the diameter of a revolver can be checked and the microscope is made compact. Then, illuminating efficiency and contrast can be improved.

Title: Clock control circuit
Inventor: YAO SEIJI
IPC: H03M1/12
Filed: 1985-11-09
Abstract: PURPOSE:To minimize a linking distortion by adding a prescribed linking detector in a clock phase locking system for receiving a dot-interlaced image signal. CONSTITUTION:A digital input video signal 24 is supplied to a linking detector 10. Then, a maximum value selector 14 selectively extracts a linking detecting additional pulse part sent at every fixed period and holds the maximum value of the linking. A comparator 17 compares a current value out of the outputs of a selector 14 with a value obtained before one period. A reversible counter 22 executes the counting based on control signals outputted from AND gates 20, 21 which are obtained based on said compared result. The output of the counter 22 is converted into an analog value by an A/D converter 23 and applied to an adder in the clock phase locking system. Consequently, the linking can be minimized.

IPC: G11B7/00
Filed: 1994-10-18
Abstract: PURPOSE: To accurately judge the inserting direction of a recording medium by detecting an optical recording area based on a quantity of reflected light from the recording medium by moving a light beam in the track traversing direction of the recording medium and reproducing a prescribed information. CONSTITUTION: A card feed motor 37 is driven by an MPU 33 to make a light spot access a track in which card type 7 is recorded, and the card type 7 is read out by moving the light spot on this information track in a fixed direction. Subsequently, whether the card type 7 is correctly read out or not, is checked by the MPU 33 based on a reproducing result. At this time, when the inserted optical card is in such a state as shown in the three cases in the figure, the direction of data in a line and the reproducing direction are identical with each other, and hence the card type 7 is correctly read out, and in this case, the process is completed by setting the moving direction in the forward direction.

IPC: B29C45/73
Filed: 1984-11-29
Abstract: PURPOSE:To prevent a product from being deformed by cooling thereby obtaining a highly accurate configuration and to make compression molding at low pressures possible, by providing heater members to extend into cavities. CONSTITUTION:High-frequency heaters 20 are placed in tip sections of a plurality of knockout pins projecting into cavities 18 and are connected to a prescribed high-frequency power source. A fixed mold 16 is formed with holes 21 that communicate the cavities 18 with a circuit 22 for feeding a melted resin, and the products molded in the cavities 18 are pushed out by the knockout pins 19.

Abstract: PURPOSE:To provide a structure for an end face light emitting device with high emission effect, and its manufacturing method. CONSTITUTION:A region 15 with an activated layer thicker than that of an activated layer 14 is formed on the rear side of the activated layer 14 other than the side facing to a light emitting end face 10. The region 14 with a thin activated layer serves as a light amplifying region and the region 15 with a thicker activated layer serves for confining the emitted light in the activated layer and providing it to the light amplifying region so that the power of the emitted light can be enhanced. After a current blocking layer 2A is removed, a groove formed thereon with varied widths so that a clad layer 3A, which is grown on the groove, is formed in a shape that is evenly at a narrow part, but is bent deeply at a wide part in the groove. Also the activated layer 4A formed thereon is bent deeply and grown thicker at a wide groove part, and thereby the thickness of the activated layer can be changed in regions. Consequently, the activated layers with different thicknesses can be simultaneously formed for different regions.

Abstract: PURPOSE:To facilitate a learning process by securing a consistent operation among those operations of three different levels, i.e., the designation of an object, the selection of a task and the selection of a treatment. CONSTITUTION:The control is always shifted to the related logical machines 12-15 by a control processor 8 with push of a hard key 4. The machines 12-15 are set under an action mode where a user can select an operating object. When this subject is selected,the machines 12-15 are set under a second action mode where the treatment to be applied to the selected object can be prescribed by the user. Each structure of machines 12-15 is subject to a grammar. Thus the user must prescribe an object at first and the select a treatment (action) against the object. This structure of each machine is equal to the relation between a subject and a predicate of a sentence. Furthermore this concept reflects the daily logic of the user. Thus a learning process is facilitated.

Abstract: PROBLEM TO BE SOLVED: To obtain a high efficiency of a display material by a synergic effect of fluorescence and afterglow of films by laminating both of fluorescent and afterglow films having a proper compounding ratio of particles with a film material. SOLUTION: This display material consists of, from the left side of the figure, a black light 1, the afterglow film 2 and fluorescent film 3. UV rays emitted from the black light 1 transmits through the particles compounded in the afterglow film 2 and irradiates the fluorescent film 3. Thereby, the afterglow film 2 produces yellow green afterglow color and the fluorescent film 3 also produces yellow green color. By turning off the black light 1 at this time, the afterglow yellow green color of the afterglow film 2 is reflected by the fluorescent film 3 to give a yellow green color. As for the basic colors of the afterglow film 2 and the fluorescent film 3 by UV rays, the afterglow film 2 has light- accumulating property and gives a yellow green color, while the fluorescent film 3 has fluorescent property and gives a blue color.  Therefore, by punching an arrow pattern in the afterglow film 2, an arrow in blue-white fluorescent color is obtd.
