Patent JP-H01114088-A (JP)
Title: Laser apparatus
Inventor: OTA JUN
IPC: H01S3/092
Filed: 1987-10-28
Abstract: PURPOSE:To discontinue a useless discharge by a method wherein a thyristor is provided in the discharge circuit of a flashlamp and a giant pulse laser beam is detected and a trigger is generated to turn a main thyristor off. CONSTITUTION:A laser element 1B is excited by a flashlamp 2. At the time of laser oscillation, a laser beam is made to be a giant pulse laser beam by a Q-switch element 1A provided in a laser resonator. A part of the laser beam is detected by a photodetector 10A and converted into a signal for turning a commutating thyristor 11 by a commutating trigger circuit 10B. When the thyristor 11 is turned on, one end of a commutating capacitor 12 is given a ground potential and the other end is rapidly given a negative polarity. A discharge current which makes the flashlamp 2 emit a light flows into the capacitor 12 side and a current applied to a main thyristor 4 is discontinued and the thyristor 4 is turned off. A useless discharge is discontinued and an unnecessary double-pulse laser beam is eliminated.

The compound having phase-transfer activity is preferably a soluble nonionic compound such as crown ethers, polyethylene glycols or cyclodextrins. An agent for forming a photocatalyst composition is produced by mixing the modified titanium oxide sol together with a precursor compound of a metal oxide (metal alkoxide, metal acetylacetonate, etc.) in a common solvent and/or dispersing medium. The agent is applied to a substrate (e.g. glass), dried and heat-treated to obtain a film composed of a photocatalyst composition.

If it is smaller than the mentioned thickness, the flanged part might come off. The laminated product (a) is, if necessary, composed of a low adsorbing resin layer 3 which prevents the adsorption of an aromatic component of the content laminated on the innermost surface. The cup-shaped container 2 has a flange 21 formed, and is formed from the laminated product (a) using sheet forming technique. The cup-shaped container 1 is filled with the content and a metal lid is tightly fastened. Thus the flange 21 does no longer come off and no inferior fastening of the metal lid occurs after winding process.

Title: Encoding device
Inventor: ABE SHUJI
IPC: H04N19/126
Filed: 1992-10-12
Abstract: PURPOSE:To improve the encoding efficiency in a lower layer, to improve the image quality in the lower layer and to equalize the image quality of the reproduced image of each layer. CONSTITUTION:A hierarchizing circuit 80 hierarchizes the conversion factor from a DCT circuit 13 and imparts it to a quantizing circuit 81. The hierarchizing circuit 80 does not transmit the conversion factor of an AC factor as for a hierarchy 2X2. Therefore, the rate control of the hierarchy 2X2 is not performed by the quantizing circuit 81 and the encoding amount of the hierarchy 2X2 can be lowered. Thus, as the predicted error in the lower layer becomes small, an encoding efficiency is improved. The image quality of an upper layer is also improved.

Abstract: PURPOSE:To obtain an accurate floating capacitance type level change detector usable at a narrow place with a detection range wide sufficiently and with very limited effect in the perimeter by malfunctioning and undesired radio waves. CONSTITUTION:A PLL circuit 22 is connected to an OSC 21 having a time constant determining section to which is connected a sensor 26 for detecting a change in the floating capacitance in contact or in no contact with a liquid body as object to be detected. A self traveling frequency f2 and a range of capture range of the PLL circuit 22 are set separately so that a range of change in output frequency f1 of the OSC21 determined by a comprehensive time constant as a total of a change value of a electric capacitance (floating capacitance) or the like detected with the sensor 26 and a preliminary time constant preset with the time constant determining section reaches the inside of the capture range of the PLL circuit 22. Thus, a level change of the liquid body is detected by checking a change in a control voltage V2 of the self-traveling frequency of a VCO22b generated associated with the change in the floating capacitance as detected with the sensor 26.
