Title: Compound type semiconductor element and its manufacture
Inventor: KIMU KUWAN SUU
IPC: H01L21/8249
Filed: 1989-03-24
Abstract: PURPOSE: To increase the degree of integration and operating speed of a composite semiconductor element, by mounting a bipolar element formed by minimizing the width of its inactive base region and a highly integrated CMOS element on one water in a mixing state. CONSTITUTION: After an N<+> -buried layer 104 is formed on the surface 102 of a P<-> -type silicon wafer substrate by diffusion, an N-type epitaxial layer 103 is grown and deposited by doping the layer 104 with phosphorus. Then, after a P<+> -type junction separating area 106 is prescribed by utilizing a field mask, boron is injection into the area 106. After injection, an oxide film 107 is grown and the gates 111 of an NMOS element and a PMOS element and the emitter 112 and collector 113 of a bipolar transistor are fomred by anisotropic etching. Then, the sources/drains 116 of the PMOS and NMOS 117 elements are formed by implanting boron ions. Finally, an inactive base region and junctions are fomred so as to reduce the base serial resistance of the bipolar transistor.

IPC: B41J2/32
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce energy required for image formation. SOLUTION: When an image is recorded on a thermal medium 255, the medium 255 is radiated from a single radiation transmitter 205 and a first part of the medium is heated up to a first temperature lower than a threshold recording level. The medium 255 is further radiated from same radiation transmitter 205 and other part of the medium 255 is heated up to a second temperature higher than the threshold level thus recording an image on the medium 255.

Title: Precipitation of tantalum or niobium compound
Inventor: TAKAI TETSUO
IPC: C01G35/00
Filed: 1980-06-03
Abstract: PURPOSE: To prepare the titled compound having low impurity content, by adding a precipitant to a Ta or Nb solution acidified with hydrofluoric acid.  
     CONSTITUTION: Ore containing Ta or Nb oxide is dissolved in hydrofluoric acid, and the solution is made to contact with an organic solvent to extract the Ta or Nb in the solution to the organic solvent. The organic solution of Ta or Nb is then made to contact with a dilute mineral acid to obtain an aqueous solution of Ta or Nb. Hydrofluoric acid is added to the aqueous solution until the concentration of  free hydrofluoric acid reaches to ≥0.1M/l, and the hydrofluoric acid solution of Ta  or Nb thus obtained is mixed with a peroxide (e.g. H 2 O 2 ). The molar concentration ratio of the Ta or Nb to the peroxide is selected to ≥1. A precipitant (e.g. aqueous ammonia) is added to the mixture, and the pH of the solution is adjusted to ≥5 to precipitate the Ta or Nb compound. By this process, a Ta or Nb compound having low content of Sb, Si, etc. can be obtained.

Title: Automatic focal point adjusting device
Inventor: TOYODA HIDEO
IPC: H04N5/232
Filed: 1984-04-13
Abstract: PURPOSE:To widen the operating extent and to improve the operating speed of an automatic focal point adjusting device, by detecting plural frequency components different in band in an image pickup signal and performing an arithmetic process on them, then, driving the focal point adjusting device of a lens so that the amplitude of the processed output signal becomes maximum. CONSTITUTION:In case where the amplitude of a high-frequency component does not reach a prescribed level and the signal of a low-frequency component detecting circuit 8 is outputted, a gain controlling circuit 16 is controlled so that its gain becomes larger and the loop gain of this system is increased. When the amplitude of the high-frequency component reaches the prescribed level and a high- frequency component becomes to be outputted, the gain of the gain controlling circuit 16 becomes smaller and the loop gain of this system is decreased. Since the loop gain is decreased at the moment when the amplitude of the high-frequency component becomes larger in such a way, the operating extent can be widened and the operating speed can be increased without making hunching.

Filed: 1987-03-30
Abstract: PURPOSE:To enable transferring to a recording medium low in smoothness,by moving a thermal recording head along ink film opening parts of a plurality of ink film cassettes in a retractable manner, once transferring inks to an intermediate recording medium, and finally transferring the inks to a final recording medium. CONSTITUTION:A thermal recording head 1 is fixed to a fixed frame 2 rotatably supported on a slide base 5 through a rotatable shaft 3. The head 1 is pressed, in a body with the frame 2, against a platen roller 38 in an ink film cassette 46, and is vertically moved as the slide base 5 is moved. At the time of recording, the head 1 is located oppositely to a platen roller part of the ink film cassette for the first color, and an intermediate recording medium 15 is fed while recording simultaneously with rotation of the platen roller 38. Then, the medium 15 is fed to a take-up roll 14, and in the course of this process, transferring onto a final recording medium is conducted by a heating head 16. Since transferring to the final recording medium is thus performed through the intermediate recording medium, transferring to a recording medium low in smoothness can be performed.

IPC: F02D41/20
Filed: 1994-04-13
Abstract: PURPOSE:To attain both high speed performance and high resolution without changing a pulse rate. CONSTITUTION:A deviation DELTAtheta between a target throttle opening DELTAo and a throttle opening theta is computed (115).

Abstract: PURPOSE:To prevent the double writing only on the partial area among the recording area of the rotary recording media, by outputting the data double write-in inhibit signal to the recording media, depending on the supply of the write-in mode display signal and the write-in inhibit signal given externally. CONSTITUTION:When the switch 5 is connected to the inhibit position, the signal at the switch 5 opnes the gate of the logical product gate circuit 7 via the logical sum gate circuit 6 and closes the inhibit gate circuit 9 while the output of the flip flop 3 indicates write-in inhibit state, so that the write-in data is not delivered to the write-in head 10. When program gives the write-in inhibit or write-in permission, it  can be made by selecting the flip flop 4. For example, when write-in inhibit is  desired by program, the flip flop 4 is set with the inhibit command in place of the  switch 5, and when permission is desired, the flip flop 4 is reset with the permission command.
