IPC: H01L29/786
Filed: 1984-02-06
Abstract: PURPOSE:To enable the formation of a semiconductor layer with excellent reproducibility and uniformity and with a simple structure and sufficient properties for practical use, by implanting ions into at least a part of polycrystalline silicon formed on the substrate for rendering it amorphous. CONSTITUTION:Poly-Si is adhered by CVD or the like on an amorphous insulation substrate 1 such as a quartz plate or the like consisting of SiO2, and then pattern etched to form a polycrystalline silicon layer 2. Thereafter, ions of Si<+> for example are implanted into at least a part of polycrystalline silicon layer 2 to form an amorphous region 3. This amorphous region 3 is formed only in the central portion of the polycrystalline silicon layer 2, while both sides thereof are left as polycrystalline regions 2a and 2b. The polycrystalline silicon layer 2 thus partially rendered amorphous is heat treated so as to cause the amorphous region 3 to crystal grow in solid phase and to form a solid-phase growth region 4. When said heat treatment is effected at a temperature within the range from 600 deg.C-700 deg.C, approximately cylindrical large crystal grains H are formed throughout the width of the amorphous region, and thus the solid-phase growth region 4 having good reproducibility can be obtained.

Title: Sealing device for dry type gas holder
Inventor: FUJIWARA MASAHARU
IPC: F17B1/06
Filed: 1982-02-10
Abstract: PURPOSE:To reduce the flow-down amount of sealing liquid by a method wherein a member for preventing rotation of a piston, a movable sealing piece or the like are utilized. CONSTITUTION:When a piston 4 is rotated, a circumferential gap is caused between a rotation preventing member 15 and a sliding seal member 9, however, the movable seal piece 20 is pressed to both sides of the rotation preventing member 15 of the piston by the energized force of a spring 22 to hold said gap in constant and, thus, the flow-down amount of the seal liquid is held in constant. A clearance between the sliding seal member 9 and the member 15, which is generated by the wear of the seal member 9, is compensated by the movable seal piece 20 and thereby enabling to keep a stable sealing performance for a long period of time.

Title: Glass base plate for master
Inventor: ARISAWA MAKOTO
IPC: G03F1/00
Filed: 1989-01-27
Abstract: PURPOSE:To form a clear pattern by providing a metal compd. layer on a resist-coated face. CONSTITUTION:An appropriate metal compd. layer (e.g. CrO) 11 is provided on one face of a disc-shaped glass base plate 1 for master. After the glass plate 1 is washed and dried, the face on which a metal compd. layer 11 is formed is coated with a resist 12 and a desired pattern is formed on a pattern forming part by using a light exposing means. Then, the resist is developed by using e.g. an alkali aq. soln. and all the exposed part with light is removed. Only unexposed part remains as a developed resist 12a and is dried to obtain a master 3 wherein a desired pattern is formed. As the metal compd. 11 has an extremely low reflective coefficient of the light exposing means, such as about 4%, when a desired pattern is formed on the resist 12, interference hardly occurs. Therefore, the edges of the developed resist 12a are clearly formed and the pattern of the master 3 also becomes precise.

Filed: 1991-01-19
Abstract: PURPOSE:To reduce estimation errors by storing the frequency correlation functions corresponding to a plurality of delayed profiles beforehand, obtaining the correlation coefficients of the receiving levels of the received radio waves having a plurality of frequencies, and obtaining the function, which agrees most excellently, and the value of delay spread. CONSTITUTION:Radio waves in a plurality of frequencies are received with a receiving antenna 1. The receiving level at every frequency is measured with a field-strength measuring device 3. The data are sampled at a constant distance interval with the pulses from a vehicle-speed measuring device 4 and digitized. The data from an A/D converter 5 undergo processing in a shadowing removing device 6. The correlation coefficients of the receiving levels are obtained for all measured frequencies with a correlation-coefficient operating device 7. Correlation functions corresponding to a plurality of delay profiles are stored in a ROM 8 beforehand. The correlation function uses a delay spread as a parameter. A delay-spread computer 9 obtains the delay spread, where the error between the stored correlation function and the correlation coefficient of the receiving level becomes the minimum value. The delay spread is displayed on a display device 10 as the delay spread at this point.

Title: Charge control method and charge controller
Inventor: TERADA JIYUNJI
IPC: H02J7/04
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To shorten the charge waiting time and the time required for charge by charging a battery with a pulse current, which is made by turning on and off the current and whose maximum value is not over the quick charge current, when the battery temperature is at or under the lower limit value where a quick charging of the battery is possible. SOLUTION: A battery temperature detector 34 amplifies the current charge of a thermistor which changes by a battery temperature T, and converts it into a specified voltage, and inputs it into a CPU 26. However, it performs charge, suppressing the average current low, by turning on the off a relatively large charge current into a pulse current in the case that the battery temperature is lower than the temperature range where the battery can be charged quickly. However, the maximum value of the pulse current is the current of quick charge.  Then, when the battery temperature T reaches the set value not less than the lower limit value of the temperature range, where the charge is possible in the middle of charge, it shifts to quick charge, and when the battery temperature T goes down to the lower limit value or under in the middle of quick charge, the charge is stopped, and it goes into standby. As a result, the battery is charged with a pulse current being made by turning on and off the current whose maximum value is not over the quick charge current, so a charge-standby time and the required time for charging can be shortened.
