Title: Electronic musical instrument
Inventor: KAWASHIMA SUSUMU
IPC: G10H1/36
Filed: 1996-05-07
Abstract: PURPOSE: To provide an electronic musical instrument which produces big sounding musical sounds when the sound volume increases and also produces delicate sounding musical sounds when the sound volume decreases. CONSTITUTION: The volume of musical sounds is controlled on the basis of level control data. For the level control data, initial touch data and after touch data are used. The volume of the musical sounds corresponding to the level control data are stored as sound volume change curves. The curves of each musical sound is varied in the mode in which plural musical sounds are produced. Please note that the rise of each curve is especially varied. Thus, when the level control data are small and the sound volume is small, only smaller number of musical sounds are produced practically and the sounds are made delicate. When the level control data are large and the volume is also large, the musical sounds become big because all musical sounds are produced.

Title: Method and device for preparing three-dimensional body
Inventor: CHIYAARUZU DABURIYU HARU
IPC: C08F2/00
Filed: 1989-05-01
Abstract: PURPOSE: To allow a three-dimensional object to be fabricated rapidly, securely, accurately, and economically by applying a spot of UV light as a graphic pattern to a working surface of a fluid medium to form thin, solid layers and automatically superposing successive adjacent layers. CONSTITUTION: Energy is applied as a graphic pattern at a fluid surface to form thin, solid, individual layers on the surface. Each such layer is made as thin as possible, equal to or less than 1 mm, in order to shorten the production time. Such thin layers result in the improved precision of the object being formed. As a fluid medium cures and a solid material forms to define one lamina, the lamina is moved away from the working surface and the next lamina is formed which is adhesively connected to the previously formed lamina to form the entire three-dimensional object.

Title: Manufacture of semiconductor device
Inventor: HAGIWARA KATSUTOSHI
IPC: H01L21/306
Filed: 1988-05-10
Abstract: PURPOSE:To increase the area of an electrode in a trench and to obtain a large capacitance by so forming an amorphous silicon layer as to raise the center of the bottom of the trench. CONSTITUTION:A trench 2 is formed in a silicon substrate 1, and an amorphous silicon layer 3 is formed by an anisotropic depositing method such as an ECR plasma CVD method and the like. Thereafter, when it is etched with (HF, HNO3) solution, a conical amorphous silicon layer remains. That is, since a film formed by the anisotropic deposition method has weaker adhering force in a vertical direction than that in a parallel direction with respect to the surface formed with the film, its sidewall is removed more rapidly by etching. Thus, the area of the part to become the electrode of the capacitor is increased, and a semiconductor device having a large capacitance can be obtained.

Title: Repairing method of wood pattern for casting
Inventor: OOTSUKA HITOSHI
IPC: B22C7/00
Filed: 1979-09-05
Abstract: PURPOSE: To easily reproduce a wood pattern having reached its service limit and save the cost of manufacturing patterns by making a mold with said pattern, removing the inner side surface of the pattern and injecting a reinforcing coating agent in the clearance of the mold thereby repairing the same.  
     CONSTITUTION: Molding sand is packed in a pattern 1 made of wood which has worn and become dimensionally inaccurate upon longterm use, whereby a mold 2 is made. Thence, this mold 2 is taken out from the wood pattern 2, and the thickness 4 nearly constant over the entire surface of the inside surface 3 is removed by using woodworking tools or the like, whereby a corrected pattern 1' is made. On the other hand, a release agent is coated on the entire outside surface 5 of the mold 2 and the pattern is again fitted into the cavity in the corrected pattern 1', then the space 4' of nearly uniform thickness is formed between the removed inside surface 3' of the corrected pattern 1' and the outside surface 5 of the mold 2. Next, a reinforcing coating agent 6 prepared by adding a hardener to a molten synthetic resin is injected into the space 4' and the pattern 2 is taken out after it has solidified. Hence, the corrected pattern 1' assumes the state that the reinforcing coating film has stuck over the entire surface of its inside surface, thus the repaired pattern of an accurate size is obtained.

Here, for example, about 400V voltage of the feed line 5 to the load is lowered to about 12V and the voltage is applied to a current leakage detecting circuit 47. Meanwhile, when current leakage occurs in the feed line 5 to loads, a zero-phase transformer 6 detects the current leakage and sends out a detection signal to the current leakage detecting circuit 47. Then, electricity is applied to a thyrister 48 and a transistor 62 through a SCRT terminal in the circuit. Consequently, a relay 50 provided with a current leakage display LED 49 and an output contact point 50a for current leakage alarming is driven.

Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To provide a communication system by which a user, who owns a communication terminal having no voice communication function, can call utilizing a position registration function. SOLUTION: In this communication system 1, a telephone number for voice communication is assigned not only to a speaking terminal 4 having the voice communication function but also to a position registering terminal 3 having no voice communication function. At the time of registering a position, the position registering terminal 3 transmits the absence of the voice communication function to an exchange 6. When call incoming for voice communication is requested to the position registering function 3, call incoming to the position registering terminal 3 is transferred to terminals A-1 to 5x close to the position registering terminal 3 and capable of voice communication by the exchange 6.  Thus, in the communication system, 1, the requested call is connected and presented to the user of the position registering terminal 3 while using the terminal closest to the position registering terminal 3.
