Abstract: PURPOSE:To improve the characteristics of a liquid crystal display panel in a thin MOS film semiconductor device by forming the Si film in thickness lower than 1,000Angstrom  of a channel part and increasing the contact part larger than that, thereby improving light leakage characteristic. CONSTITUTION:When an Si film 1 made of polycrystal or single crystal is covered on a substrate formed with an active region, the thickness of an Si film 1 having ordinarily a thickness of 2,500-3,000Angstrom is set to lowr than 1,000Angstrom  at the channel part only. The thickness of the contact parts disposed at both sides of the channel part is increased with the films made of the films 1, 5 laid with Si films 5, 6 under the channel and contact parts. Subsequently, a gate oxidized film 2 is covered on the channel part and the contact part including the parts, a gate electrode is formed on the channel part, and aluminum wirings 3, 4 are mounted through windows opened at the film 2 on the contact parts 5, 6. In this manner, the leakage current when the light is irradiated is reduced, and the erasure of the stored charge is reduced, thereby preventing the decrease in the displaying function.

IPC: G01L9/00
Filed: 1981-03-19
Abstract: PURPOSE:To improve the accuracy with a simple construction by outputting an electrical signal from a vibrator in which a disc-shaped piezo-electric body is pasted on either or both sides at the central part of a circular metal body having a mass larger at the peripheral part than that at the center thereof. CONSTITUTION:A vibration made up of a disc-shaped piezo-electric body 2 pasted at the center of a circular metal body 1 which is made thicker at the peripheral part than that at the central part to increase mass. The vibrator is mounted on the wall surface 4 of the water tank in such a manner that the non pasted surface of the piezo-electric element 2 gets into contact with a liquid such as water. If the water pressure in the water tank 10 changes, the vibrator outputs an voltage corresponding to the force thereof from a terminal 3. The output voltage of the vibrator becomes large in the resonance frequency if the force of the water pressure is the same while almost constant if is small in the frequency enough below the level. Therefore, the vibrator is designed according to the frequency to be detected. This can improve the accuracy with a simple construction.

Title: Method and device for encoding voice
Inventor: MATSUNAGA KEIJI
IPC: G10L19/035
Filed: 1995-02-06
Abstract: PURPOSE: To prevent a band to which no bit of a high frequency band is allocat ed from existing by allocating the number of bits of an irreducible minimum for the specified band. CONSTITUTION: The number of bits (information amount) allocated to the whole bands are set in an initial value zero bit, and SMRs (signal masking ratio) of respective bands are calculated. NMRs (noise masking ratio) are calculated from the SMRs and SNRs(signal noise ratio) of respective bands. Together with that, SARs(signal minimum audible limit ratio) are calculated. The band having the maximum NMR among respective bands is detected, and the band is defined No. 16. The No. 16 is made a NMRB(maximum noise masking ratio band), and whether or not the NMR of the No. 16 arrives at a minimum allocation threshold value is judged, and when smaller than the minimum allocation threshold value, bit allocation is ended. Then, by allocating the number of lowest bits even for the band of a small dynamic range by using auditory sense, the bands to which no bit are allocated are reduced.

Title: Process for purification and concentration of tocopherol
Inventor: ISHII KIETSU
IPC: C07D311/72
Filed: 1984-03-05
Abstract: PURPOSE:To purify tocopherol in high yield, by carrying out the steam distillation of a tocopherol-containing oil sludge under a specific acid value to remove the low-boiling impurities, purifying the residue in the presence of an aqueous solution of an alkali, and subjecting to high-vacuum distillation. CONSTITUTION:Low-boiling impurities are removed from tocopherol-containing oil sludge by the steam distillation of the sludge to an extent to leave an acid value of 5-20. The distillation residue is purified with an aqueous solution of an alkali (e.g. sodium carbonate), distilled in high vacuum, and if necessary, treated with a strongly basic anion exchange resin to purify tocopherol. Since the low-boiling impurities are removed beforehand, the purification can be carried out easily compared with the purification by esterification, and the loss of tocopherol in the alkali purification step can be decreased. The purity of tocopherol can be improved easily because the system is maintained in high vacuum during the vacuum distillation process such as molecular distillation.
