Title: Ultrasonic piezoelectric element and sensor, and manufacture of spectrum microscope and piezoelectric element
Inventor: NAKASO NOBUTAKA
IPC: H01L41/22
Filed: 1995-03-09
Abstract: PURPOSE: To ensure high spatial resolution by preventing generation of noise due to edge ultrasonic wave transmitted from the edge part of an ultrasonic piezoelectric element. CONSTITUTION: The ultrasonic piezoelectric element 1 comprises a lower electrode 2, an upper electrode 3 of identical shape, and a piezoelectric membrane 4 sandwiched between and deposited on the upper surface of a coupler 5. The lower electrode 2 is rotary shifted by an angle α1 from the axis 8 of the coupler 5 whereas the upper electrode 3 is rotary shifted by an angle α2 from the axis 8 of the coupler 5. The following relationship α1 -α2 =180 deg./n is satisfied, where (n) is the order of rotation (integer) of axis symmetric electrode. The lower and upper electrodes 2, 3 can be deposited relatively easily using a mask of same profile produced through electrical discharge machining, for example. An ultrasonic transmission surface is formed at the intersection of the lower and upper electrodes 2, 3 overlapping by an angle 180 deg./n. The ultrasonic transmission surface includes a point and bottom part. Edge ultrasonic waves, radiated from the point and bottom part, interfere each other and disappear. Consequently, noise due to edge ultrasonic wave can be eliminated.

Title: Manufacture of planetary gear type reduction gear
Inventor: YAMAMOTO KAZUHIDE
IPC: F16H1/36
Filed: 1987-03-03
Abstract: PURPOSE:To obtain the simple constitution at a low cost and increase the strength of material and improve the finishing precision by integrally forming the supporting pin and the flange of a planetary gear type reduction gear through the cold forging work. CONSTITUTION:When a material 20 is loaded onto a lower die 19, and an upper die 18 is swung in the tilted state by the theta deg. around a rotary shaft phi, the material 20 is pressurized in the direction of arrow A, and a part is pushed forward B in a recessed groove 19a for forming a supporting pin, and a plurality of supporting pin parts 21 are formed. In the forging work, the pressing force of the upper die 18 acts locally onto the material 20, and the operation load can be reduced in comparison with that in the conventional extrusion forging work. After the work, the material 20 is taken out from the lower die 19, and a supporting body is completed after the necessary posterior work. Since a single material is put into the cold forging by swinging the die, the supporting pin part and the flange part of a planetary gear type reduction gear can be formed integrally, and the simple constitution can be obtained at a low cost, and strength can be improved and the high precision finishing is permitted.

Abstract: PURPOSE: To avoid the erroneous reading caused by the soiled area by providing the reference reflection part within the processor to read the white reference level, setting the 1st and 2nd levels based on the reference level and thus setting the  threshold value.  
     CONSTITUTION: The scanning is given to original 12 irradiated by light source 11 and along scanning line 13, and then the information on line 13 is applied to pickup element 16 via lens system 15 to be converted into the electric signal via element 16. In this case, reference reflection part 18 is scanned immediately before or after scanning of original 12, and thus white reference signal 17a is produced to analog signal 17. Then signal 17 sent from element 16 is applied to detector 22, mean value circuit 27 and comparator 29 each in synchronization with the clock sent from control part 25. And the output of detector 22 is voltage-divided through voltage divider 24, and thus the 1st and 2nd levels are set featuring the threshold value higher than the 1st level the mean level of which is lower than the reference level and the threshold value lower than the 1st level the mean level of which is lower than the reference level. And then the comparision is given at comparator 29 between these levels and the level of supplied signal 17. Thus the binary coding is carried out.

Title: Bipolar semiconductor integrated circuit device and manufacture thereof
Inventor: KITAGUCHI HIROHISA
IPC: H01L29/73
Filed: 1988-03-04
Abstract: PURPOSE:To enhance performance and to improve mass productivity of a bipolar semiconductor integrated circuit device by making a semiconductor substrate and its epitaxial layer of the same conductivity type (N-type), and forming the collector layer of a P-N-P transistor and isolating an N-P-N transistor forming part by using a low concentration p-type buried layer. CONSTITUTION:A semiconductor substrate 21 and its epitaxial layer 28 are formed in N-type, and the collector layer of a P-N-P transistor is formed by a low concentration P-type buried layer 24b. Accordingly, a contact part of the layer 24b with a high concentration N-type layer 21 is eliminated in the P-N-P transistor part, thereby reducing the collector capacity of the P-N-P transistor. Since P-type buried layers 24a, 24b are of low concentration, the influence of automatic doping is reduced in a step of forming an epitaxial layer. Thus, a bipolar semiconductor integrated circuit device having high performance can be obtained by enhancing its mass productivity without increasing the number of steps.
