Title: System and method for distributing contamination program
Inventor: TAKUBO AKIO
IPC: G06F21/12
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a system for distributing programs to prevent illegal copying. SOLUTION: A program distributor transmits contamination programs which are previously contaminated and stored in the contamination program storage part 21 of a contamination program distributing device 1 through a distributing part 6, enciphers purifying information through the use of the distribution public key of a user and transmits it as enciphering and purifying information. The contamination programs are received by the contamination program executing device 2 of the user and stored in a contamination program storage part 8. Received enciphering and purifying information is stored in an enciphering and purifying information storage part 20. When the user executes the contamination programs, the contamination programs in the contaminated state are successively shifted to a program executing part 9 and the execution is started.  At the same time, enciphering and purifying information is decoded by using the reception secret key of the user by the work of a dynamic purifying mechanism 10 and a contamination is removed in a purifying part 16 just before the contaminated part of the contamination program is executed, based on the purifying information and the programs are executed.

Title: Operation method of incinerator
Inventor: HIGUCHI NARIAKI
IPC: F23G7/06
Filed: 1985-08-21
Abstract: PURPOSE:To prevent the generation of NOX in an incinerator and deodorize foul odor from a human wastes treating plant at low cost by blowing waste gas containing high concentration foul odor into a burning chamber as control air for temp. of the incinerator and also waste gas containing low concentration foul odor as burning air and control air for temp. of the incinerator. CONSTITUTION:Waste gas generated from a human wastes treating plant 1 and containing NH and high concentration foul odor is directly blown into a burning chamber 4 of an incinerator 3 as control air for temp. of the incinerator 3. In the incinerator 3 NOX is generated and cracked into N2 and H2O by NH3 in waste gas to reduce NOX and also high concentration foul odor is deodorized by thermal cracking. On the other hand, low concentration foul odor generated from a human wastes treating plant 1 and transferred to a chamber 6 by a foul fan 5 and accompanied with foul odor generated from a waste pit 7 is blown from the underside of a fire grating as burning air via a gas type air preheater 9 by a forced draft fan 8 and a part of the mixed gas is blown into the burning chamber 4 as control air for temp. of the incinerator. Thus, low concentration foul and waste pit foul odor are simultaneously deodorized and treated.

Title: Optical head device
Inventor: TODE HIDEKAZU
IPC: G11B7/09
Filed: 1986-08-05
Abstract: PURPOSE:To eliminate the asymmetry of a focus error offset in the tracking direction and to reduce its quantity remarkably by arranging a flat place element tilted with respect to a direction orthogonal to an information track as a rotary axis. CONSTITUTION:The flat beam splitter 3 is tilted by 45 deg. with respect to a radial direction at the focal point of an optical disk as a rotary axis Y-Y. That is, the radiated luminous flux 2 from an LD1 is radiated in the tangential direction of the focal point of the information track 5, reflected vertically into the optical disk by the splitter 3 and collected by a condenser lens 4. The spot center position shown in mark X moves in a direction BD at an angle of 45 deg. with respect to a split line similarly to that of a conventional example according to the tracking, but no distortion is caused to the shape of spot. Thus, the change in the incident angle in the splitter 3 of the reflected luminous flux 6 with in the meridional plane is scarcely induced, and the factor in the focus error offset is only the effect of the spot movement.

Abstract: PURPOSE:To apply squelch independently of the content of a data at a line fault and to prevent malfunction even against a data unchanged for a prescribed time or over by providing a signaling state detection circuit or the like. CONSTITUTION:A signaling state detection circuit 10 detects it that a transmission signaling SS at a point B is idle and the state of a reception signaling SR demultiplexed by a demultiplex circuit 3 being busy continues for a prescribed time or over and outputs a squelch signal. Then the signalings SS, SR are detected by the circuit 10 at a fault of the circuit and squelch is applied when the both reach a prescribed state. Moreover, the signaling SS and the signaling SR inverted from the pattern of the signaling SR are detected and squelch is applied when the both reach a prescribed state. Thus, the application of squelch in error due to tentative intermission of the data in a conventional equipment is prevented and accurate communication is attained.

Title: Overheat preventive method for line-feeding motor in printer
Inventor: ITO SHUNICHI
IPC: H02P1/16
Filed: 1987-07-24
Abstract: PURPOSE:To contrive prevention of overheating of an LF motor without causing an increase in manufacturing cost, by obtaining a predetermined rest time before driving the LF motor during the operation of a second timer started when the total number of line-feeding pulses exceeds a predetermined value. CONSTITUTION:A first timer TM1 is started after a power supply is switched ON. Thereafter, when a predetermined time is counted to reach a time-out condition, it is judged whether the total number of line-feeding pulses is more than a first predetermined value, and when the total number is not more than the predetermined value, the first timer TM1 is restarted. When the total number of the pulses is more than the first predetermined value, a second timer TM2 is started, and in a counting period of the timer TM2, a predetermined rest time can be taken before driving an LF motor (d). When the second timer TM2 reaches a time-out condition, it is judged whether the total number of the line-feeding pulses is more than a second predetermined value. When the total number is not more than the second predetermined value, the first timer TM1 is started, whereas when the total number is more than the second predetermined value, the second timer TM2 is restarted. Thus, during the operation of the second timer TM2, a predetermined rest time can be taken before driving the LF motor (d). Therefore, it can be contrived to prevent the LF motor (d) from overheating.

Title: Electric angle detector
Inventor: TAGA YOSHIAKI
IPC: H02P6/18
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of strange sounds, when an electric angle is measured. SOLUTION: A measuring voltage is applied to a specified winding combination (Steps S205, S225, S245), and the variation of a current flowing in each winding is detected (Steps S215, S235, S255), by utilizing the fact that the electric angle of a three-phase synchronous motor corresponds to the inductance between windings. When a driving current is flowing in the three-phase synchronous motor, a current flowing between each winding and the next winding attenuates, compared to the case where the driving current is zero, so the current value is corrected (Step S260), referring to a table on the basis of the variation of the current. An electric angle is found (Step S270), referring to the table, on the basis of the corrected current value.  As the result of this, it becomes unnecessary to perform measurement after always having returned the driving correct to zero, and it enables shortening of the measuring time, thus preventing the generation of strange sounds.

Filed: 1994-08-05
Abstract: PURPOSE:To reduce the ripple in output voltage to improve response speed, to extremely facilitate the adjustment of output and to prevent the irregularity of temp. characteristics. CONSTITUTION:The output voltage from a switched capacitor circuit 32 is held in predetermined timing by a sample hold circuit 33 to obtain the output voltage corresponding to applied pressure.
