Title: Sealer
Inventor: TSUKAMOTO NOBUMI
IPC: B65B11/00
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To secure sealing of a packaging material to make the heat-sealed state favorable to quicken the packaging operation by providing a bendable flexible sealing member when a packaging material is sandwiched between sealer bodies. SOLUTION: Opposite sides 4b of a cylindrical film 4 are folded in a gusseted fashion. When an object to be packaged is conveyed together with the film 4 into between lateral sealers, upper and lower sealer bodies are rotated at prescribed rates to seal the part between the film 4 and the object to be packaged from above and below. At that time, upper and lower pieces 4a, 4d of the film 4 are pressed and heat-sealed by heated sealing bars 25, 26 respectively. When the film 4 is sandwiched between the sealing bars 25, 26 from above and below, the sealing bars 25, 26 are flexed throughout the width of the film 4.  Therefore, even a part of the film 4 where the thickness is increased can be pressed under the same pressure and temperature as those applied to a thinner part to be sealed and as a result the film 4 can be sealed securely throughout the width under generally uniform conditions.

Title: Synchronizing signal reproducing circuit
Inventor: TAKAGUCHI TATSUSHI
IPC: H04N9/44
Filed: 1989-05-30
Abstract: PURPOSE:To prevent the system clock from being fluctuated depending on the content of a picture by using a line burst signal not subjected to the effect of ghost as a reference signal for generating a system clock. CONSTITUTION:A switch Sw2 is switched selectively with a signal from a latch circuit 20 being a means detecting whether or not an input signal is normal. A burst gate pulse (non signal line and a line burst gate succeeding to a fixed signal line such as VITS or the like) appears by a synchronizing signal pulse reproducing device 19 at a normal input via the switch Sw2 and a switch Sw1 is turned to the contact (a). A burst signal of the succeeding line to the fixed signal such as VITS or the like and a non signal line is supplied among outputs of a BPF 11 is fed to a PLL oscillation circuit 16 to lock the burst of the line not subjected with the effect of ghost. Thus, the synchronizing signal is not moved unstably together with the change in the video image.

Abstract: PURPOSE:To always perform the tracking servo with high stability and high accuracy in simple constitution by feeding the low-frequency component of the voltage applied to a tracking actuator coil back to a compensating circuit. CONSTITUTION:The tracking error signal supplied to a terminal 16 is given to a tracking actuator coil 19 via a phase compensating circuit 17 as well as an integration compensating amplifier circuit 18. In this case, the output signal is supplied to a Zener diode via an LPF20 if the output signal of the circuit 18 is set within a low-frequency band. The level of the tracking error signal delivered from the circuit 17 is lowered by a detection signal obtained when the signal level is higher than the prescribed value. While said output signal is supplied as it is to the coil 19 in case the output signal of the circuit 18 is within a high- frequency band.

Title: Apparatus and method for detecting speed/acceleration
Inventor: FUKUSHIMA HIROKAZU
IPC: G01P15/16
Filed: 1993-05-16
Abstract: PURPOSE:To calculate the velocity and the acceleration with high accuracy by using a timer for calculating the measuring time and a counter for measuring the sum of the number of pulses input within the measuring time. CONSTITUTION:A timer calculates a measuring time M (=K+DELTAk) by adding an appearing time DELTAk until the first pulse appears after a preset time K passes, to the preset time K. A counter measures the total number of pulses (=N+1) input in the measuring time M. A speed operating device detects a speed V through operations based on the total number of pulses (=N+1) and the measuring time M. At this time, the speed V is equal to [(N+1)XL]/(K+DELTAk) wherein L is the distance between pulses and is a constant value. An acceleration operating device detects an acceleration (a) (=dV/dt) by operating the speed V. Accordingly, the number of pulses input in the measuring time can be counted correctly and at the same time, the appearing time of the pulse can be correctly measured by the timer.

Inventor: YANAGIHARA MANABU
IPC: H01L29/47
Filed: 1991-06-10
Abstract: PURPOSE:To enable the Schottky diode characteristics and FET characteristics of excellent gate electrode to be displayed. CONSTITUTION:Within a two layer structure of an SiN film 6 and an SiO2 film 7 for a spacer layer to form a gate electrode by lift off step, the window- making steps of the SiO2 film 7 and the SiN film 6 are performed by siotropical chemical dry-etching step respectively using fluoric acid and CF4+O2. Through these procedures, since the window-making step of the SiN film 6 is performed by the isotropical chemical etching step causing little damage to the GaAs surface, good Schottky characteristics and FET characteristics can be displayed. Meanwhile, since the SiN film 6 can be thinly formed, the resist pattern need not be expanded during the etching step thereby enabling the gate length conforming to the design to be stably secured.
