Title: Logic verification system using state transition diagram
Inventor: HANAJIMA IKUO
IPC: G06F17/50
Filed: 1993-12-21
Abstract: PURPOSE:To efficiently perform a design job by simulating a state transition diagram itself by test data near to natural language after a circuit is designed by the state transition diagram. CONSTITUTION:When a logic circuit is designed, the functional operation of the circuit is described by the state transition diagram (file 2). The state transition diagram itself is simulated to confirm the normalcy of a model described by the state transition diagram (step 3), and the transition of a state can be confirmed visually (step 4). It is enough to describe only a condition to transit the state as the test data required in such simulation, which enables the condition to be described in a form near to the natural language. The state transition diagram for which simulation is completed goes to the one without inconvenience for state transition, and the state transition diagram is developed in functional descriptive language or a function diagram (step 5), and furthermore, it is logically synthesized (step 7), thereby, a complete circuit design job can be finished.

CONSTITUTION:The constitution consists of a laser light source 1, a collimator lens 2 to change the dissipating luminous flux from the laser light beam 1 to the parallel luminous flux, a composite luminous flux generating optical system 3 to produce the composite light beam by superposing the luminous flux of different wavelengths over the luminous flux passed through the collimator lens 2, a condensing lens 5 to converge a composite luminous flux, and a deflecting system where a layer 6 of the transparent medium with a plane of incidence 6a parallel to the mirror surface 7a is united on the mirror surface of a pyramidal mirror 7, and the composite luminous flux incident upon the plane of incidence are separated according to the wavelength and emitted. In this case, the composite luminous flux is incident upon the transparent medium 6, and reflected on the mirror surface 7a, then the luminous flux of different wavelengths is emitted separately from the plane of incidence. This constitution enables scanning by means of a plurality of luminous flux without generating any changes to their pitches.

Title: Microcomputer control circuit for high-frequency heating device
Inventor: YUASA FUMIO
IPC: H05B6/68
Filed: 1987-12-21
Abstract: PURPOSE:To make a pulse drive with TRIAC for a magnetron power supply and ensure low power consumption by detecting a power voltage and power frequency with a microcomputer and arcing TRIAC via the estimation of the 0-degree phase of a current with the detected voltage and frequency values. CONSTITUTION:The voltage of a commercial power supply 7 is kept low and rectified and smoothed with an AC/DC conversion circuit 5, thereby obtaining a d.c. voltage. This voltage is divided with a resistor and the divided voltage is inputted to the analog terminal AN of a microcomputer 1. This divided voltage changes depending upon the voltage value of the commercial power supply 7 and, therefore, the microcomputer 1 makes a measurement with an A/D conversion function with the divided voltage incorporated, and estimates therefrom the voltage value of the commercial power supply 7. From the value so obtained, the 0-degree phase of a current from a magnetron power supply 8 is assumed to have a phase lag tl1 from the 0-degree phase of the predetermined voltage. In this case, if the microcomputer 1 outputs a timing lagging by tl1, from the 0-degree phase of power supply voltage detected through the trailing end of a signal TNT having a period T and a control pulse signal P on a timing lagging by (tl1+T/2), TRIAC 2 is turned on with the 0-degree and 180-degree phases of the power supply current.

IPC: G03G9/087
Filed: 1992-12-02
Abstract: PURPOSE:To firmly fix a charge control agent on toner grains efficiently by adding the charge control agent to a cake of colored spherical particulates in the moist state. CONSTITUTION:Colored spherical particulates are acquired by polymerizing polymerizable monomers in a suspended medium in the existence of a colorant and/or magnetic powder by way of suspending them in the suspended medium. The particle diameter of these colored spherical particulates is made to be within a range of 3-50mum, favourably within a range of 3.5-20mum. Additionally, favourably, after adding water insoluble particulates (for example, hydrophobic silica) in the suspended solution at the point of time when the rate of polymerization of the colored spherical particulates becomes 90% or more, it is heat treated at the temperature of 50-98 deg.C and made into a block by way of fusing the colored spherical particulates with each other as well as carrying out polymerization aging. This particulate block is made into a moist cake by way of filtering and separating it from the suspended medium. To this moist cake, a charge control agent is added. Thereafter, drying treatment is carried out, and it is cracked.

Title: Intake system for motorcycle
Inventor: FUCHIGAMI WATARU
IPC: F02M35/16
Filed: 1990-11-27
Abstract: PURPOSE:To reduce the extent of intake air resistance by installing an air cleaner case in an interval between a first chamber housing an air cleaner element and a second chamber connected with an intake passage, and a partition wall with plural pieces of connecting ports being curved into a circular form and interconnecting both these chambers, respectively. CONSTITUTION:A rear surface of an air cleaner element 25 comes cleaner to a bend 51 of a partition wall 46, and almost the whole circumference of this air cleaner element 25 is surrounded by an air cleaner case and the partition wall 46. During engine driving, intake air conducted into a spatial part 28 of the air cleaner element 25 from an intake 39 is inhaled in a first chamber 47, where inlet suction pressure has uniformly acted at a connecting port 55 of the partition wall 46 after evenly passing through each part of the air cleaner element 25. Since a duct 56 jutting out more in the rear than an opening 45a at the upper end of an intake pipe 45 is installed in the connecting port 55 of the partition wall 46, the intake air conducted into a second chamber 48 is guided into the upper end opening 45a of the intake pipe 45 as turning over its flow direction toward the upper part from the vicinity of a lower end of the intake pipe 45, thus flowing path length of the intake air is secured to the full.

Title: Solid-state image-pickup device
Inventor: NAKASHIBA YASUTAKA
IPC: H04N5/359
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To reduce the parasitic capacitance, which is generated between a metal film, used as a light-proof film, and a metal wiring, to raise the image- pickup sensitivity of a solid-state image-pickup device. SOLUTION: The electrons from among electrons and hole which have been generated by light entering a solid-state image-pickup device via an opening part formed in a metal film 112 which is used as a light-shielding film, are stored in a depletion layer under a photogate 102. Then, a control pulse ϕR in a MOSFET 104 for reset use is set at a low level, and when a low-level voltage is applied to a control pulse ϕPG, the electrons under the gate 102 go over a potential barrier formed under a MOSFET 103 for transfer use and are transfered to a floating diffused layer 206. A potential in the layer 206 is varied according to the number of the electrons transferred, and a change in the potential is outputted to an external circuit via a metal wiring 113, which connects a gate electrode of a source follower amplifier 105 with the layer 206. Since the source potential in the amplifier 105 is fed to the film 112, variation in the potential in the film 112 becomes roughly equal to that of the potential in the layer 206, and the parasitic capacity between the film 112 and the metal wiring 113 is reduced.
