Title: Tunnel transistor and fabrication thereof
Inventor: UEMURA TETSUYA
IPC: H01L29/88
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a tunnel transistor in which a high current density is realized and a fabrication method thereof. SOLUTION: Butter layers 2, 3 are formed sequentially on a semiinsulating GaAs substrate 1 followed by formation of a drain layer 4 having superlattice structure where a p<+> -In0.2 Ga0.8 As layer degenerated to have a mean lattice constant equal to that of GaAs and a degenerated p<+> -GaAs0.38 P0.02 layer are laminated alternately. A channel layer 6 having a conductivity type different from that of the drain layer 4 is then formed while touching the drain layer 4 partially. An inter-band tunnel junction is formed at the interface between the channel layer 6 and the superlattice drain layer 4 and a tunnel current flows between the source and the drain as a result. A differential negative resistance appears in the current-voltage characteristics when the channel concentration is controlled by the gate voltage to a gate electrode 8.  Since lattice mismatch to the substrate has no effect, tunnel current density is increased.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of components and to improve assemblability into a door by a method wherein a door is made to be capable of being placed in a superlock state by a guide part and the engaging part of a link attached to a base. SOLUTION: One end part is engaged with an actuator lever 16, an engagement part 38 at the other end part is engaged with the guide part of a base, and a link 20 coupled to a first lock plate 17 is provided. The engagement part 38 of a lick 20 moves a first guide part 21a according to rotation of the actuator lever 16 between a lock position and an unlock position and moves a second guide part 21b according to rotation between a lock position and a superlock position. When the engagement part 38 is positioned at a guide part 21b, the first lock plate 17 is brought into a non-rotatable state through rotation operation of a second lock plate 18 to the unlock position side. Thereby, a need for a support plate is eliminated, the number of parts is reduced, and ability of assembly into a door is improved.

Title: Opening-position detection
Inventor: MANABE YUKIO
IPC: B23K9/12
Filed: 1987-10-14
Abstract: PURPOSE:To detect an opening position accurately and to shorten an operating time, by comparing luminance difference between two different picture elements on the same scanning line and a threshold voltage, without comparison operation of a part on the long-time side after 'white' is judged. CONSTITUTION:A part, on which slit light 2 is projected, on a material to be measured 3, is picked up with a TV camera 4. The image is stored in an image RAM 6. The data stored in the RAM 6 are read out and inputted into a CPU 7. The difference between the luminance of an arbitrary picture element and the luminance of a picture element in the vicinity of said picture element on the same scanning line is computed. The difference is compared with a preset threshold value. When the luminance difference is larger than the threshold value, a picture element between said arbitrary picture element and said adjacent picture element is made to be 'white' and other picture elements are made to be 'black'. This is accomplished by binary coding. Then the primary and secondary differentiations of line images are performed. The maximum value and the minimum value of the secondary differentiation values are taken out. In this way, the position of the opening feature points (a bottom part 3a and both shoulders 3c and 3d) are detected. The results are outputted to a positioning motor 12 for a welding torch, works and the like.

IPC: H04N19/44
Filed: 1995-10-05
Abstract: PURPOSE: To provide a highly efficient run length decoding circuit capable of corresponding to a picture element clock signal with high frequency at real time. CONSTITUTION: After initializing all data words stored in a 1st scan converting RAM 131a to '0', only a code-added level data word is overwritten on a position '0' in the RAM 131a which is specified by a zigzag scanning address based upon a zero run length data word. Thus one block stored in a 2nd scan converting RAM 131b is read out and initialized during the writing of only non-zero components out of 84m8 components constituting one block in the RAM 131a. During the writing of only non-zero components of the succeeding block in the RAM 131b, one block stored in the RAM 131a is read out and initialized.

Title: Method and device for rendering, game machine, and computer readable recording medium for storing program for rendering three-dimensional model
Inventor: IMAI HITOSHI
IPC: A63F13/55
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To plot the outline of a three-dimensional model arranged in a virtual space by simple processing. SOLUTION: A model for outline plotting is acquired in initialization (step S2). This model for outline plotting includes a three-dimensional model, and each face is the reverse face of a corresponding face of the three-dimensional model. The model for outline plotting is arranged in state setting in a virtual space (step S3). When an outline of the three-dimensional model is plotted (step S4), plotting processing of the model for outline plotting is performed (step S5). After the model for outline plotting is subjected to transmission conversion or the like, only front faces seen from a view point are taken as the plotting object to erase concealed faces, thus plotting the model. Since the model for outline plotting is larger than the three-dimensional model, it is partially plotted on the outside of the three-dimensional model as the result of erasing concealed faces.  Finally, the threedimensional model is plotted as usual (step S6).

Title: Logic circuit
Inventor: UOSUMI HIROYUKI
IPC: H03K19/088
Filed: 1991-10-08
Abstract: PURPOSE:To obtain the logic circuit whose switching speed is not reduced even when an undershoot takes place in an output terminal. CONSTITUTION:When an undershoot is caused at an output terminal 20, a current supply means 100A is activated and a current is supplied from a power supply VCC to an output terminal 20 via a resistor R7 and a transistor(TR) T8 the reduction in a potential due to the undershoot at the output terminal 20 is compensated by the current supply. Thus, even when an L level is inputted to the input and an undershoot takes place at the output terminal, the transit time of the TR T6 from the OFF to the ON state is almost the same as that of a normal operation. Thus, a change from an L to an H at the output terminal is not slow.
