Title: Viterbi decoder
Inventor: KAMATA TAKEHIRO
IPC: H03M13/41
Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To realize a high error correction capability even in the case of consecutive decoding for convoluted codes transmitted through a plurality of transmission system whose transmission capacity differs from each other. SOLUTION: In the case that an error rate detection unit 105 detects that a state of a transmission channel is deteriorated and the transmission channel is noisy, and a changeover detection unit 106 detects that a transmission system capable of delivering data with a high transmission capacity is changed into that with a small transmission capacity. An initialization unit 107 generates a maximum number of path metrics storable in a path metric memory 104 when the path metric exceeds a threshold in the switching timing, so as to relax the effect of disturbance of the path metric before switching. However, generates zero when the path metric is smaller than the threshold to initialize the path metric as an initial value respectively.

Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive measuring instrument with high measurement accuracy, which is a jig mounted on a projector and can measure a floating amount of a terminal in an electronic component. SOLUTION: An element 1, to be measured which is an integrated circuit or a connector, is stable in an erected attitude where a terminal 10a is placed in a horizontal surface. A mirror-type measurement instrument 12 is mounted as a jig on a projector, and can measure as a floating amount how the terminal 10a floats from the flat surface in an erect attitude, to measure whether plural terminals 10a are arranged in a designated flat surface. A projected light 100 of a light source built-in the projector is directed from a through-hole vertically upward and reflected by mirrors 1, 2, 3 to irradiate the terminal 10a on a pedestal 8 as light 103a. The irradiating light 103a is partially intercepted by the terminal 10a to form light 103b. The light 103b is the contour image light of the terminal 10a.  The light 103b is reflected by the mirror 4 to enter an optical system of the projector to be converted, thereby forming an image as the contour image. The floating amount of the terminal 10a is measured by observing the contour image.

Title: Inverter type engine generator
Inventor: OGURA KAZUHIKO
IPC: H02P9/04
Filed: 1990-10-05
Abstract: PURPOSE:To prevent the overrunning of the engine of the title generator by operating a rotating speed adjusting means to an idling position through an actuator for adjusting rotating speed when the voltage value of the generator abnormally drops from an appropriate value against the frequency value. CONSTITUTION:When a fault, such as short circuit, disconnection, etc., occurs to part of a generator 2, the AC voltage value detected by means of a voltage detecting means 7a abnormally drops, but the frequency value does not show such abnormal drop. Therefore, the voltage value shows an abnormal drop against the frequency value. When a voltage/frequency detecting means 17 detects such abnormal voltage drop, a rotating speed adjusting means 10 is operated to an idling position through an actuator 9 for adjusting rotating speed. Since the voltage/frequency detecting means 17 works to operate the rotating speed adjusting means to the idling position, a voltage comparing means can prevent the overrunning of the engine through the rotating speed adjusting means.

Title: Thermal transfer printer
Inventor: TAKANASHI RYOYU
IPC: B41J13/02
Filed: 1988-10-25
Abstract: PURPOSE:To make possible the pressing of a paper feed roller and the winding of transfer paper using a single drive motor by allowing a pressing mechanism to be actuated by the drive in a single direction of the motor and a winding roller to rotate by the drive in a reverse direction. CONSTITUTION:If a drive motor 37 rotates forward, a one-way clutch 34 releases the engagement of a worm wheel 35 with a drive shaft 33. The rotary power of the worm wheel 35 is applied to the drive shaft 33 through a torque limiter, and then causes a shaft 10a to rotate through a gear 31 and a one-way clutch 32. Consequently, a winding roller 10 is driven by rotation to take up transfer paper 8 at high speed. Next, if the drive motor 37 is reversed, the worm wheel 35 rotates in an arrow direction, resulting in the rotation of a rotary shaft 26 through the one-way clutch 34, drive shaft 33, a drive gear 30, a gear 29 and a one-way clutch 28, and the subsequent pressing downward of a support shaft 20a by rotation of a pressing member 25. Thus a paper feed roller 20 is pressed on recording paper 17 at the uppermost position in a paper feed tray 14.

Title: Object transporting method for aluminum sorter
Inventor: KAWAMURA KIYOSHI
IPC: B03C1/23
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To smoothly transport objects at a high speed by transporting the objects by means of a single conveyor which houses a magnet roller within a cylindrical roller at a terminal. SOLUTION: Magnetic materials, such as steel cans, are attracted and are housed in a container 8 at the time of passing the position of a magnetic material removing conveyor 4. The magnet roller 5b is housed in the cylindrical roller 5a rotatably separately from the rotation of the cylindrical roller by having a spacing and is arranged alternately with N poles and S poles in a circumferential direction. The magnet roller 5b at the terminal of a main conveyor 2 rotates at a high speed. Eddy currents are generated by electric power changes (alternating magnetic fields) in aluminum materials which are nonmagnetic and conductive, by which repulsive force is generated between the magnet roller 5b and the aluminum cans with each other. Consequently, the aluminum cans are driven by the high-speed rotation of the magnet roller 5b and are jumped out of the terminal of the main conveyor 2.  After the aluminum cans come into collision against a buffer 6, the aluminum cans are housed into a container 10. Bottles, plastic containers, etc., fall downward from the terminal and are housed in a container 9.

Title: Logical simulation method
Inventor: HOSHINO YASUAKI
IPC: G06F17/50
Filed: 1994-11-02
Abstract: PURPOSE: To improve the precision of a gate propagation delay time even under the condition wherein the gate propagation delay time depends upon operation frequency. CONSTITUTION: When variation of the input signal of an input pattern 1 is observed in a step S1, the logical level of the output signal corresponding to the logical level of a new input signal is determined in a step S2 on the basis of a truth table 2. In a step S3, parameters required to calculate the gate propagation delay time and the transition time of the output signal are found from a combination of logical levels of the input signal by using a parameter table 3. In a step S4, a correction quantity for the threshold value of the input signal is found from the combination of the logical levels of the input signal by referring to the parameter table 4. In a step S5, a temporary output value is calculated from the values calculated in the respective steps.  In a step S6, the point of time when the temporary output value exceeds the threshold value of the output signal is calculated and variation of the output signal is reserved to carry on the logical simulation.
