Title: Disk housing device
Inventor: HISATOMI YUICHIRO
IPC: G11B17/26
Filed: 1993-03-05
Abstract: PURPOSE:To house carriages under the close-contact laminated state without making a space between the individual carriers by providing a carriage supporting means on a stocker bottom surface and supporting an end part on the side of one surface opposite to the other surface of the 2nd carriage. CONSTITUTION:A stopper 141 is brought into contact with an engagement protrusion of the carriage 58 positioned below the drawn carriage 59 so as to lock this position. Thus, the carriage 59 is drawn out of the stocker into a slot 89 formed between carriage stoppers 86 and 87, and is reproduced. When the carriage is housed from a reproducing position into the stocker, a motor is rotated counterclockwise, and a change plate 43 is also moved in the reverse direction, so that the carriage 58 is brought into the stocker. In this position, a carriage lifter 140 provided on the plate 43 is released from engagement with the engagement protrusion of the carriage as shown in the figure, and the carriage 58 is released from lifting.

IPC: H04L25/02
Filed: 1981-05-11
Abstract: PURPOSE:To enable the reception of a tri-state data with a simple constitution, by operating an exclusive use diode switch and a rectifying circuit depending on an input signal whether it is a mark or a space and cutting off the said diode when the input signal is zero. CONSTITUTION:When a space signal of minus polarity is applied to a terminal 22 based on a terminal 21, diodes 29 and 31 are turned on, and an AC current from an oscillator 23 is transmitted to a transformer 35 via the diodes 29 and 31. The current is converted into a DC with a rectifying circuit 37 and a data signal with minus polarity is obtained at a terminal 41. When a mark signal with plus polarity is inputted, diodes 32 and 34 are turned on, the AC current from the oscillator 23 is rectified at a rectifying circuit 38 and a data signal with plus polarity is obtained at the output terminal 41. On the other hand, if the input data signal is zero, the diodes 29,31 and 32,34 are all turned off, the AC current from the transformer 24 is interrupted and the output at the output terminal 41 is also brought to zero.

Title: Manufacture of semiconductor device
Inventor: ITO YUTAKA
IPC: H01L21/304
Filed: 1991-04-04
Abstract: PURPOSE:To polish a thick-film SOI film and to make it into a thin film having the good uniformity in its film thickness. CONSTITUTION:A second SiO2 film 5 is deposited on an opening part 4 formed in a semiconductor film 3 on a first insulator 2. The film thickness of the second SiO2 film 5 is set to a target film thickness for an SOI. After that, resist is left only in the opening part by a resist coating operation and by an etching- back method, and the second SiO2 film 5 other than the bottom part of the opening part 4 is removed by a wet etching operation or a dry etching operation. After that, the SOI film is polished and made into a thin film by using an abrasive material until the second SiO2 film 5 on the bottom part of the opening part 4 comes into contact with an abrasive plate. When a material whose polishing rate is large with reference to Si and very small with reference to SiO2 is selected as the abrasive material, the second SiO2 film 5 at the bottom part of the opening part 4 acts as a polishing stopper, and the SOI film can be polished over the whole surface of a wafer and can be made a thin film so as to make the uniformity of its film thickness good.

IPC: H01L31/04
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a solar battery having a excellent radiation resistance, a light weight, and a high conversion efficiency. SOLUTION: On an undoped semiconductor substrate 10, a lower electrode layer 11 is provided to form a solar battery layer 2 in one portion above the lower electrode layer 11 and a lower electrode 4 in another portion. An upper electrode layer 16 and an upper electrode 3 are provided on the solar battery layer 2.

Filed: 1992-02-21
Abstract: PURPOSE:To improve the picture quality by controlling the quantization step size corresponding to a unit block to a small size and assigning a large data volume to the unit block. CONSTITUTION:An average level detecting circuit 5 holds color difference data CR and CB, which are inputted in line sequence, between block lines for the purpose of attaining the coincidence between the timing of luminance data Y1 to T4 and that of color difference data CR and CB.

Title: Oscillation reducing apparatus for workboat or the like
Inventor: WATANABE TAKEKATA
IPC: B63B39/06
Filed: 1980-06-02
Abstract: PURPOSE: To reduce the oscillation of a hull, by providing a plurality of flap plates which elastically allow the inward revolution, near the lower end of each side plate, and revolving said flap plates in order to absorb the wave energy when the wave force acts thereon.  
     CONSTITUTION: A plurality of flap plates 3 are attached near the lower end of each side plate 1c. These flap plates 3 can revolve inwardly through hinges 6 and are normally held by means of revolution angle regulating chains 5, at such positions that the upper ends thereof extend obliquely outwardly. When the wave force acts on the flap plates 3, they revolve inwardly, contracting oil-pressure buffer-restoring members 4 capable of expansion and contraction. Consequently, the water between the side plate 1c and the flap plates 3 is pushed up and made to flow outwardly from the upper ends of the flap plates 3, and thereby the wave energy is absorbed. When the wave force acting on the flap plates 3 becomes weak, they are restored to their original positions by the functions of the oil-pressure buffer-restoring members 4.

Title: Die cooling device for rotary die casting machine
Inventor: UENO TOYOAKI
IPC: B22D17/22
Filed: 1985-04-08
Abstract: PURPOSE:To rotate a rotary table in the mid-way of cooling of dies and to improve productivity with simple constitution by supplying cooling water to a water feed trough which rotates integrally the rotary table from a water feed pipe inserted into the annular aperture thereof. CONSTITUTION:The cold water from a water feed source is supplied through the water feed pipe 52 into the water feed trough 51 from which the water flows through pipings 55, 56 and a cooling piping 53 toward a discharge trough 57. The water cools the dies 27, 28 in the mid-way of flowing toward said trough, thereby solidifying and cooling a molten metal. A float 62 turns upon attainment of the water in the trough 57 at the prescribed level, then a pump 60 is operated by an electric signal from a sensor 63 to drain the water from the trough 57 until the water therein decreases down to the prescribed level of below. The pump 60 is thereafter intermittently run according to the volume of the water. The rotary table 11 rotates in the mid-way of the cooling and the trough 51 and a cooling water pump 54, pipings 55, 56, 58 rotate as well to insert the pipe 52 into the annular aperture 51a. Since the drain pipe 58 is inserted into the annular aperture 57a in the above-mentioned manner, the cooling of the dies 27, 28 is not hindered even if the table 11 rotates.

Abstract: PURPOSE:To eliminate the ununiformity in the width of character constitution lines and the height/width of the whole character due to the difference of display positions by allowing a data converting means to convert outline data obtained by the movement of a contour line moving means into dot data. CONSTITUTION:If movement inhibition information 43 is not stored in an information storing means 14 when the number of width-direction picture elements included in a contour line is a value corresponding to line width setting data 42 stored in a line width setting/storing means 14, the contour moving means 34 moves one of two contour lines, and when the information 43 is stored, moves only the contour line whose movement is not inhibited based upon the information 43 relatively to an image screen in the direction and by the distance corresponding to the data 42. The obtained outline data are converted into dot data by the data conversion means 36. Consequently, ununiformity in the width of character constitution lines and the height/width of the whole character due to the differences of display positions can be eliminated.
