Title: Amplitude modulator with electroabsorption modulator
Inventor: GRANDPIERRE GEORGES
IPC: H04B10/43
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To apply amplitude modulation to an optical signal with an electric signal having N-sets of states (N is 2 or over). SOLUTION: The modulator has a shaping means 1 at an upperstream of 2 input sections and one of the input section receives an electric signal S in states N and, a state of its output transits from one state of the N states to other state in response to a level of the electric signal in the states N exceeds a prescribed threshold level and a state of its output transits from the other state of the N states to one state in response to a level of the electric signal in the states N is less than a prescribed threshold level. The prescribed threshold level relates to the one state and the other state in pairs and stays between a level of the two states and is different from the level of the two states.

Filed: 1993-11-10
Abstract: PURPOSE:To execute a positioning operation at a high speed and corrdctly and further to cope with electronic components of different sizes in the same way by providing a light source on the fixed side of a processing stage and by varying an irradiation distance between a reflecting plate for the electronic component irradiation and the light source, in an image processing of the electronic component held by a head. CONSTITUTION:First to third sucking heads 15 to 17 are mounted on a head support part and an electronic component is sucked by sucking nozzles 15a and 16a. A camera 18 for detecting the position of a base is fitted to the third sucking head 17 and a ring light 19 for illumination is installed at the lower end of the camera 18. A reflecting plate 21 being a white disk made of Teflon is fixed to a sucking nozzle 20 of the third sucking head 17. The reflecting plate 21 moves vertically with the sucking nozzle 20 and thereby an irradiation distance between the reflecting plate 21 and a light source is made variable. Regulation is conducted to make the silhouette of the component clear by raising the sucking nozzle 20 when the component to be subjected to an image processing is large and by lowering it when the component is small.

Title: Glass bottle
Inventor: SAITO SHINJI
IPC: B65D23/00
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To improve the water hammer-resistant strength of a glass bottle by taking a primary factor of a water hammer phenomenon into consideration. SOLUTION: A position where a maximum inner surface-axial stress is generated due to the internal pressure is set to an upper portion spaced perpendicularly apart by 3 mm or more from the deepest part of a bottle inner face bottom. By spacing the position where the maximum inner surface-axial stress is generated due to the internal pressure from the deepest part of the bottle inner face bottom, the stress to be generated at the deepest part of the bottle inner face bottom, where impact traces are most generated, becomes smaller, and a possibility that the bottle is broken is also thereby reduced.  The fact that the position where the maximum inner surface-axial stress is generated due to the internal pressure is set apart from the deepest part of the bottle bottom means concretely that the deepest part of the bottom is allowed to approach the central side of the bottle as near as possible.

Title: Production of electrophotographic sensitive body
Inventor: TSUCHIYA SOJI
IPC: G03G5/00
Filed: 1988-11-08
Abstract: PURPOSE:To improve chemical stability and durability by subjecting a photoconductor soln. to be used for forming a photoconductive layer on a conductive base to a low temp. treatment, then using the soln. for forming the photoconductive layer. CONSTITUTION:The photoconductor soln. to be used for forming the photoconductive layer on the conductive base is subjected to the low temp. treatment and is then used for forming the photoconductive layer. The intramolecular interaction, for example, the interaction between the arom. rings is intensified and a certain association state is formed in the soln. by subjecting the photoconductor soln. to the low temp. treatment. This association state is maintained even if the soln. temp. is returned to room temp. thereafter and, therefore, the viscosity of the soln. is high. Since the intramolecular interaction between the photoconductor and a binder resin is strong with the photoconductive layer formed of such soln., the sensitivity and stability are improved and the film (layer) structure is uniformized. The high sensitivity and the excellent stability are obtd. in this way.

Title: Data holding system using arithmetic logic unit
Inventor: FUKUDA YURIKO
IPC: G06F7/57
Filed: 1985-12-16
Abstract: PURPOSE:To process the instructions with higher efficiency with no addition of hardware by providing a data holding function to an arithmetic logic unit ALU by means of the no-function cycle of said ALU. CONSTITUTION:The addresses added to the operation codes are read into a IH register 21a and a IL register 21b and undergo the increment of '1' respectively. These address data are supplied to a memory as the index offset data addresses. Thus the index offset data is read out of the memory and set to both registers 21a and 21b to undergo the increment of '1'. Then those addresses are supplied to the memory as the immediate data addresses. Thus the immediate data are read out. Then a BX bus 19 is set at '00' to obtain the X input of an ALU 11 and the index offset data is added as the Y input. The result of this arithmetic is equal to the index offset itself and the ALU 11 attains a data holding function.

IPC: G06F11/28
Filed: 1989-10-30
Abstract: PURPOSE:To test the program performance itself by providing a converter to convert the result of measurement into a delay time and displaying the executing result of an execution means after delaying it in accordance with the converted delay time. CONSTITUTION:An execution means 2 performs a test to check whether a program works or not in the same way as a desired information processor. A measurement means 3 counts the number of instructions to be executed by the program or measures the time necessary for execution of the program. Then a converter 11 converts the result of measurement into a delay time. The executing result of the means 2 is delayed and displayed on a display means 4 in accordance with the converted delay time, i.e., the output of the converter 11. Thus a test operator 5 can objectively evaluate the program performance since the executing result is displayed on the means 4 with increased delay time as the program performance is more inferior.

Abstract: PROBLEM TO BE SOLVED: To enable a user to rapidly stop control in the midst of the control of a stage or a revolver by a control means by stopping the control of an up-and-down driving means at the time of detecting manual operation by an input means in the midst of the control of the up-and-down driving means. SOLUTION: Whether or not input by the manual operation is performed is judged based on control command information 51a when the control processing of the up-and-down movement of the stage is started. At the time of judging that the input by the manual operation is performed, processing for finishing the control by a CPU 81 is performed, and then the processing for starting the manual operation of the stage 40 is performed. Whether or not the manual operation by a handle 50 is performed is monitored by the CPU 81.  When the manual operation by the handle 50 is detected in the midst of the control of the up-and-down driving part 41 by the CPU 81, the control of the driving part 41 is stopped, so that the user rapidly stops the stage 40 and switches to the manual operation just by operating the handle 50 when the user is aware of a situation that the stage 40 is excessively moved or it is moved in a direction which is not intended by the user.
