Title: Shaping method of resist pattern
Inventor: WATANABE IWAO
IPC: H01L21/027
Filed: 1981-02-10
Abstract: PURPOSE:To obtain a resist pattern required for the high-accuracy processing of an underlying substrate by a method wherein plasma treatment using mixed gas of inert gas and hydrocarbon gas is applied to the resist pattern formed on a substrate and the sectional shape of the pattern is shaped. CONSTITUTION:Mixed gas of Ar 90%, CH4 10% is controlled by a valve while gas in a vacuum container is exhausted by a pump and the mixed gas is flowed in the container so that the gas pressure in the container may be 0.1 torr. In such a device, a steep-gradient electric field, self-bias voltage are generated around an electrode 6 by the difference between the mobility of ions and that of electrons in plasma gas and the ions in mixed gas plasma are accelerated by the inclination of the electric field to collide with a resist pattern. The pattern of polymethyl methacrylate having a development residual of 2,000Angstrom  is used as a resist pattern sample and treatment has been done for 40min under the above condition.

Title: Multiplex sound recording method of tape recorder
Inventor: YANAGI KAZUTAKA
IPC: G11B5/027
Filed: 1983-02-07
Abstract: PURPOSE:To attain the simultaneous sound recording/reproducing by using a combination head which contains sound recording reproducing heads divided vertically in terms of function to the traveling direction of a tape and stored into a case. CONSTITUTION:The sound recording/reproducing heads which are independent of each other and divided vertically to the traveling direction of a tape are set in a vertical row and put into a case to form a combination head. The head A set at the lower side to the tape traveling direction takes charge of sound recording/ reproducing with the 1st track (L channel) and the 2nd track (R channel); while the upper head B takes charge of sound recording/reproducing with the 3rd track (R channel) and the 4th track (L channel) respectively. These two heads are independent of each other and can be selected at the time of recording and reproducing. In case the head A is selected with the 1st sound recording, the 2nd sound recording is carried out by the head B while performing the reproduction with the head A. Thus it is possible to produce commercial tapes containing the vocal music, plays of musical instruments, BGM, etc. although the fine control of sounds is impossible.

Title: Ice heat storage device
Inventor: YOSHINO HITOSHI
IPC: F24F5/00
Filed: 1995-02-06
Abstract: PURPOSE: To store ice uniformly upon transferring ice and melt the stored ice efficiently by cold water returned from a heat exchanger by a method wherein a perforated plate is arranged at the part of level of water in an ice storing tank and the diameters of holes of the perforated plate are increased from the vicinity of an ice transfer device toward the distant place. CONSTITUTION: When the dam plate 9 of an ice transfer device 10 is opened, ice and water in an ice making tank 7 are moved to the side of an ice storing tank 1 due to the difference between the levels of water in the ice making tank 7 and the ice storage tank 1. The ice and water flow on a perforated plate 15 and drop sequentially from the holes of the perforated plate 15 into the ice storage tank 1. The diameters of the holes of the perforated plate 15 are increased from the vicinity of the ice supplying port of the ice making tank 7 toward a distant side from the same supplying port whereby the amount of ice, dropping into the ice storage tank 1, becomes substantially equal in the whole area of the perforated plate 15 since the diameters of the holes are small in the vicinity of the ice making tank 7 and are large in the distant area from the ice making tank 7. According to this method, ice can be stored uniformly upon transferring it while the stored ice can be molten efficiently by cold water returned from the heat exchanger 5.

Title: Piezo-electric ceramic transformer and manufacture thereof
Inventor: YAMAMOTO MITSURU
IPC: H01L41/107
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To enhance energy converting efficiency and to make it possible to achieve the compact configuration at a low-frequency band by setting a driving part and a generating part in two partitioned regions in parallel with the main surface of a piezo-electric ceramic plate in the thickness direction of the plate, providing a plurality of inner facing electrodes in these regions and polarizing the neighboring inner electrodes in the reverse directions to each other. SOLUTION: When a voltage is applied to electric terminals 23 and 23' on the side of the driving part of a piezo-electric ceramic transformer at a frequency, which is expanding in the diameter direction and excites a vibrating basic mode, a driving part 11 is vibrated at the Kr mode of the vibrating basic mode expanding in the diameter direction depending on an electromechanical coupling coefficient Kr. This vibration is transmitted to the side of a generating part 12 at the same time. On the side of the generating part 12, the vibration is converted into electric energy depending on Kr. In general, the electromechanical coupling coefficient Kr of the piezo-electric ceramic material becomes about twice as large as an electromechanical coupling coefficient K31 of the vertical vibration in the longitudinal direction of a piezo-electric lateral effect. Therefore, the energy conversion efficiency is high, and the compact piezo-electric ceramic transformer is obtained at the low-frequency band less than 150kHz.
