Title: Transmission circuit
Inventor: MIYAURA MASAO
IPC: G07B15/00
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a transmission circuit with a simple configuration, at a low cost without production of beat requiring a comparatively small structural space. SOLUTION: The transmission circuit is provided with a local oscillator 6 that generates a local oscillation signal whose frequency is made stable, an ASK modulator 1 that applies ASK modulation to the local oscillation signal to generate an ASK signal, a multiplier 8 that multiplies a frequency of the local oscillation signal to generate a frequency multiplied signal, a mixer 3 that mixes the frequency of the ASK signal with the frequency of the multiplied signal to generate a mixed signal, a band-pass filter 4 that receives the mixed signal and provides an output of an up-convert signal selectively whose frequency is the sum of the frequency of the ASK signal and the frequency of the multiplied signal, and an output amplifier 5 that amplifies the up-convert signal to generate a transmission signal.  In this case, since the mixer 3 mixes the frequency of the ASK signal with the frequency of the multiplied signal, it is not required to provide separately a local oscillator generating a mixed signal, and then the transmission circuit with a simple configuration, at a low cost where no beat is produced is realized.

Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent the feeling of visual disorder and to improve display quality by providing no seal material at a place where substrates are made to abut against each other and making liquid crystal continuously present at the abutting place. SOLUTION: Cut pieces of two liquid crystal display panels and substrates 101a and 101b are made to abut against each other, and placed on a glass substrate 22 which is coated with a seal material 20. Then a glass substrate 23 is placed on substrates 102a and 102b which are coated with a seal material 21.

Title: Pn code synchronizing method
Inventor: NOHARA KENJI
IPC: H04B1/707
Filed: 1995-06-29
Abstract: PURPOSE: To reduce computing quantity and to take synchronism in a short time by dividing an input PN code sequence and a local PN code sequence into partial systems at every same chip length and performing phase adjustment by finding the mutual correlation of the partial systems in the case of taking the synchronism of the input PN code sequence with the local PN code sequence. CONSTITUTION: Plural partial systems are generated by dividing the input PN code sequence and the local PN code sequence at every same chip length, and their phases are calculated by taking out the forefront of each partial system, and it is judged whether or not the synchronism is taken based on the threshold value. When it is judged that no synchronism is taken, it is taken by immediately shifting the phase of the local PN code sequence. In this way, the synchronism is taken in a short time by shifting the phase of the local PN code sequence by extremely quickly detecting the fact that no synchronism is taken with small computing quantity.

Title: Lapping machine
Inventor: WASHIDA AKIRA
IPC: B24B37/005
Filed: 1978-12-26
Abstract: PURPOSE:To reduce the consumption of lapping powder and raise the productivity, by transmitting a thrusting force to rings through a flexible material and almost equally thrusting the rings on a surface plate. CONSTITUTION:When a surface plate 1 is rotated in a direction A, rings 5 are rotated in a direction B and correction rings 12 are rotated in a direction C. A lapping paste is coated on a lapping surface 4 or a lapping oil is dropped onto the surface. The lapping agent is pressed into the lapping surface by cylindrical rotating surfaces 5. As a result, a workpiece is lapped by the lapping surface and the lapping agent. Since the rings 5 are thrusted through buffer rings 7, the rings 5 are almost equally pushed on the lapping surface 4 and none of the rings 5 remains out of contact with the lapping surface. Therefore, a lapping powder is uniformly pressed in. This leads to uniform lapping.

Title: Filling method for container to be sealed
Inventor: TAKAHASHI TOSHIYUKI
IPC: B67C3/04
Filed: 1991-06-06
Abstract: PURPOSE:To provide a filling method for a container to be sealed, wherein contents such as a lubricating oil can be efficiently filled into the container, leakage of the contents is not caused, and deformation of the container is economically reduced after it is tightly capped. CONSTITUTION:After filling a drum can 1 with an lubricating oil 5, the drum can 1 is tightly capped as a sealed container. In this filling method, temperature of the lubricating oil 5, with which the drum can 1 is filled, is detected and, on the basis of differences between the detected temperature and an atmospheric temperature, capping is tightly done under the conditions that a metal plate 3 of the drum can 1 is deformed in advance before the drum can is tightly capped. As a result, such deformation can be restored by expansion or compression of the lubricating oil or confined air in the drum can due to temperature differences and, accordingly, deformation of the container tightly capped can be reduced.
