Title: Nitride based compound semiconductor device
Inventor: TERAGUCHI NOBUAKI
IPC: H01L33/36
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To obtain a nitride based compound semiconductor in which a contact layer, on which a metal electrode is formed, is not stripped by varying the crystallinity continuously toward the metal electrode side from single crystal to polycrystal thereby enhancing the mechanical strength of the electrode structure. SOLUTION: A p-type GaN contact layer 2 having inclining crystallinity varying continuously from single crystal to polycrystal is formed on a single crystal p-type GaN substrate 1 and a metal electrode 3 is formed thereon by depositing Pd. The metal electrode 3 is a circular electrode having diameter of 200μm, for example, and the distance between the center of electrodes is 500μm, for example. The inclining crystallinity type contact layer 2 is grown on the single crystal p-type GaN substrate 1 by MOCVD under normal gas conditions and it is grown by lowering the substrate temperature gradually from about 1000 deg.C for producing a single crystal down to about 700 deg.C for producing a polycrystal.

Title: Method for forming three-dimensional structure of composite material
Inventor: IKEDA TAMON
IPC: B29C70/10
Filed: 1990-01-30
Abstract: PURPOSE:To easily form a three-dimensional structure of composite material by a method wherein composite materials having two-dimensional structure are impregnated with resin and, after that, laminated to one another and hardened and holes are bored on the laminated composite material with ultrasonic and then plugged up with nails, which are made of the same composite material. CONSTITUTION:Composite materials having two-dimensional structure, each of which is produced by running woof across warp, are impregnated with resin and, after that, laminated to one another so as to form the desired shape. The laminated composite material is put in a high temperature and high pressure tank so as to be turned into semi-hardened state under heat and pressure in order to produce the laminated composite material as shown at the step 3. Nail-shaped matters are produced out of thermosetting composite material by means such as lamination, filament-winding or the like and put in the high temperature and high pressure tank at the step 5 in order to produce nails in semi-hardened state under heat and pressure. Boring is performed in the laminated composite material to the directions normal to the warp and to the woof by applying ultrasonic vibration with an ultrasonic oscillator so as to soften the inner wall of each bored hole, in which the nail is plugged at the step 8 in the directions normal to the warp and to the woof. The laminated composite material under the above-mentioned state is put in the high temperature and high pressure tank at the step 9 in order to fully hardened under heat and pressure.

Title: Automatic rewinding camera
Inventor: OYOKOTA SHIGERU
IPC: G03B17/00
Filed: 1988-01-28
Abstract: PURPOSE:To prevent a fault without overloading a motor by reading the information on a specified number of photographed films automatically from a film loaded with said information and rewinding the film automatically upon ending of the photographing of the specified number of photographed films. CONSTITUTION:The film F is automatically idle fed when said film is loaded to a camera and the rear cap thereof is closed. The film is idle-fed to a specified position from a signal hole EH and is stopped when said signal is detected. The data of the film F by signal holes SH is read during this period and the data on the specified number of photographed films is preset in a down counter. The other data is stored in a register. Winding of the film F is executed upon ending of the photographing. The winding is stopped when 8 pieces of perforations PH are counted. Rewinding is executed when a signal hole WH is detected and the photographing with the final frame Fn ends. Rewinding is started when the signal holes PH are not counted in winding and the film F becomes taut. The fault is thereby prevented without overloading the motor.

Title: Segment joining structure
Inventor: YAMAMOTO MINORU
IPC: E21D11/04
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a segment joining structure capable of suppressing the set-back necessary for the segment assembly to be small, and preventing the misalignment of each segment. SOLUTION: In this joining structure 1, a line 5 extending along a short side of a base part 3a is diagonally intersected with the line in the axial direction of a tunnel and a line in the radial direction of the tunnel at the position of a folded part of a locking part 3b, and a whole joint 3 is provided on a joining surface 2a of a segment 2 in an inclined condition. The line extending along the short side of the base part at the position of the folded part of the locking part suppresses the set-back in assembling the segment to be smaller than that of a conventional structure in which a joint in a diagonally intersected condition only at the line in the axial direction of the tunnel. The misalignment is prevented by restricting the deviation (misalignment) of the segment 2 in the diameter direction of the tunnel.  In addition, the tension and the shearing force applied to the section can be simultaneously sustained by using the joint 3.

IPC: G06F17/40
Filed: 1982-02-09
Abstract: PURPOSE:To log data efficiently, by obtaining a difference between the maximum and minimum value of signals inputted along a time axis, generating a signal when the value is a prescribed value or over, and calculating the mean value when analyzing the active current of a heart. CONSTITUTION:An A/D converter 2 inputs an analog signal 1, converts the signal 1 into a digital value at each prescribed interval in synchronizing with the signal of a timer 3 and gives the output to a maximum and minimum value detector 4. Maximum and minimum value registers 5, 6 store the output level of the detector 4 respectively and output the output to the detector 4, a differential device 7 and an average device 9. The differential device 7 receives the maximum and minimum value of the registers 5, 6 and outputs the level difference to a comparator 8. The comparator 8 compares this signal with a prescribed threshold value and outputs a data transfer signal 12 when the level difference of the device 7 reaches the amplitude threshold value. The average device 9 obtains the mean value of the output of the registers 5, 6 and outputs the average value only when the signal 12 is inputted.

Meanwhile, R, G  and B three-primary color signals for pulse code modulation are compared with the boundary  color signal which is set in boundary color signal setting circuit 9, thereby detecting border lines of  the picture. Then, border lines are counted by counter circuit 10, and the number of intersecting  border lines is calculated through decode circuit 11. Meanwhile, part where three or more border  lines are intersecting to one another are detected, and the output is sent to a gate circuit and is  coded while referring to a prescribed color desigation table. As a result, the time requied for  generation of the original picture, etc., can be shortened, and coding can be performed according  to colors intended by a producer.

Title: Method and device for superposing optical elements
Inventor: HAZAMA YOSHIKAZU
IPC: G02F1/13
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To accurately superpose two substrates even when a distance between two aligning marks is long or when these aligning marks are formed by micro- lenses in the case of superposing two substrates. SOLUTION: An aperture stopping part 13a is formed on the optical path of a focus system 14a for forming a focus on an aligning mark 10a (a mark formed by utilizing the boundary part of a micro-lens) on an upper counter substrate 11A and an aperture stopping part 13b is formed on the optical path of a focus system 14b for forming a focus on an aligning mark 10b of a lower driving substrate 11B. One apeture stopping part 13a is most narrowly stopped and light passing the stopping part 13a becomes paraxial rays similarly to light projected from a point light source such as a laser. Consequently influence such as the convergence or scattering of illumination light due to the lens effect of a micro-lens having thickness in a focal depth direction is suppressed and the visibility of the mark 10a is improved.  The other aperture stopping part 13b is largely opened, so that only the aligning mark 10b of the driving substrate 11B side is observed.
