Title: Composite tile and manufacture thereof
Inventor: KAWAI KAZUYUKI
IPC: E04F13/08
Filed: 1995-05-12
Abstract: PURPOSE: To provide composite tiles which are diversified in size and shape and design and excellent in workability at light weight and easy to be manufactured by butting and burning mutual side surfaces of small molded products for expandable base composition. CONSTITUTION: A plurality of small molded products for expandable base composition are arranged and then burnt on a plate-shaped setter in such a state that the mutual side surfaces of the small molded products are butted. Then, the mutual side surfaces of a plurality of small tiles 1 are butted and united by melting so that composite tiles 2 may be available. With this, they can be molded easily by using a small-sized molding machine. It is also possible to prevent the generation of braking or cracks resultant from uneven shrinkage of the tiles during burning time and manufacture even large-sized tiles with better yields. Furthermore, this construction makes it possible to create diversified designs by changing variously the sizes, shapes, arrangement methods, coloring and thickness and so force of the small tiles 1.

Filed: 1987-05-13
Abstract: PURPOSE:To quickly perform processing by transferring block data in accordance with the conceptual execution order of an instruction, which issues an operand read-out request, at the time of absence of block data in plural buffer memories from which data can be read out simultaneously and independently of one another. CONSTITUTION:Operand addresses calculated in accordance with preceding and succeeding instructions in the conceptual execution order are sent to buffer memories 201 and 202, and a block transfer request signal circuit 301 (302) generates a block transfer request signal if a buffer data read-out request is issued but data is absent in buffers. When this signal is generated from the circuit 301 (302), a precedence deciding circuit 305 prefers the request from the memory 201 and sends a corresponding request signal to a main storage 3 and transmits it to a block transfer monitor circuit 306 to suppress following data write.

IPC: H03H9/145
Filed: 1994-04-28
Abstract: PURPOSE:To improve characteristic by evading inconvenience on the characteristic due to coupling between wiring by forming dielectric film between a specific advancing phase electrode and a crystal substrate. CONSTITUTION:The same signal is added on a phase 0 deg. electrode 3 and an advancing phase 60 deg. electrode 4, and a surface acoustic wave advances in the direction of arrowhead. The phase shift quantity (phi) of a phase by the dielectric film 5 is represented in tanphi=-(1/C) /R, (where, R>0, and the capacity of the dielectric film 5 is assumed as C, and the high resistance of the electrode as R). The phase goes to the advancing phase of 90 deg. if it is R=0, however, since a frequency is a high one, and resistance is prevented from being reduced to zero, the phase is scattered in the neighborhood of a degree between 60 deg. and 70 deg., no difference in the characteristic appears. In such a way, the phase of the 60 deg. advancing phase electrode 4 can be advanced than that of the phase 0 deg. electrode by forming the capacity by providing the dielectric film 5 under the electrode.

Title: Manufacture of thin film transistor
Inventor: KOSHIZUKA YASUO
IPC: H01L21/266
Filed: 1993-04-20
Abstract: PURPOSE:To keep a width of a field relaxing region composed of a low concentration impurity region as expected at all time in a thin film transistor of an LDD structure. CONSTITUTION:When etching is carried out using a resist mask 35 of a specified configuration as a mask, two trenches 36 are formed and a gate electrode 34a is formed of a gate electrode formation film 34 between both trenches 36 simultaneously. When impurities are implanted at a low concentration to a region shown by a mark 32b of a semiconductor thin film 32 in the state, a width of the trench 36 becomes a width of a field relaxing region 32b. In the process, both trenches 36 and the gate electrode 34a are formed simultaneously. Therefore, even if their positions deviate from a desired position, they just deviate as a whole. Therefore, a width of the field relaxing region 32b can be always made a desired width. Furthermore, this can be also applied to a thin film transistor of an offset gate structure provided with a field relaxing region comprised of a region whereto impurities are not implanted.

Abstract: PURPOSE:To ensure the privacy call and to changeover a loudspeaker talking set and a handset surely without causing mis-operation by controlling a changeover circuit so as to connect a head set to a channel when a changeover command signal is raised thereby generating a hook-off signal. CONSTITUTION:In making a call by the operation of a dial switch 12, a signal representing ''busy'' is incoming from a radio control circuit 10 to a CPU41 of an incoming/outgoing control circuit 24 when the dial information is fed to the radio control circuit 10, resulting that the CPU41 starts supplying a clock signal to a flip-flop 42. When the user turns on a changeover command switch 23 in this state, an output of the flip-flop 42 goes to ''1'', the level is stored in a flip- flop 45, resulting that a changeover control signal ''0'' is fed to changeover circuits 21a, 21b, which are changed over respectively from the handset 1 position to the head set 20 position.
