Inventor: NOGUCHI ETSUO
IPC: H01S5/227
Filed: 1984-05-28
Abstract: PURPOSE:To obtain not only oscillation at a fundamental transverse mode but also oscillation at a low threshold by positioning an N type InP layer in a multilayer structure crystal constituting a buried layer consisting of InP or InGaAsP having the functions of the constriction of currents and the formation of an optical waveguide at a section lower than the end section of an active layer in mesa structure and the P- N junction section of InP. CONSTITUTION:An SiO2 film is formed onto the whole surface of a clad layer 4, and a mask 10 composed of SiO2 is shaped to a striped form. A hetero-growth section under the SiO2 mask 10 is left to an inverted mesa shape to form mesa structure. An active layer 3 is side-etched selectively. Second buried growth is conducted, and an N type semiconductor layer 5 and a P type semiconductor layer 6 are grown in succession. A P type InP buffer layer 2a and an N type InP clad layer 4 generates a mast lance port through heat treatment at that time at a position isolated by a groove 11 removed through the side etching of the active layer 3, and upper and lower InP layers are connected rapidly through a P-N junction surface 12. Regarding second buried growth, a buried layer is grown to a mesa-etched section by utilizing properties of which a crystal does not grow on SiO2 in liquid-phase epitaxial growth. The N type InP layer in 5 is controlled so as to be positioned on the side lower than 12 at that time, and the P type InP layer in 6 is grown.

Filed: 1979-08-29
Abstract: For each axis, a cyclic transducer has a scale supplied with a sinusoidal signal from a timing unit and a cursor which provides two output signals which are proportional to the sine and to the cosine, within the elementary interval of the transducer. Sineα and cosu and the corresponding inverted signals are supplied to squaring circuits and logic which generates a three-bit number in a register defining the octant (000 to 111, i.e. 0 to 7) within which a lies. The three-bit number controls multiplexers (32 and 33) each having inputs for quadrants (0 to 7) and feeding respective sample and hold circuits (34 and 36) whose signals are NUM and DEN. The multiplexer inputs are so selected from sinα, cosα, sina and cosa that is |tanα| in octants (0, 2, 4, 6) and is |cotα| in octants (1, 3, 5, 7). is thus always positive and in the range (0 to 1). An analog- to-digital converter system (40) forms the digital value n = and n along with the lowest order octant bit address a ROM (41) which outputs the value of a within the range of a quadrant. A microprocessor (42) responds to the higher two bits to add K where K = 0, 1, 2 or 3 so as to create the final value of α. The microprocessor also keeps count of the integral displacements of elementary intervals. The apparatus enables a to be determined instantaneously, thereby eliminating the following error of known apparatuses when a is changing.

Filed: 1978-09-07
Abstract: PURPOSE: To reduce the number of decoder signals lines to an encoder part by providing a master instruction decoder to which outputs of an instruction register are all inputted and a slave instruction decoder to which outputs of the master decoder and part of outputs of the instruction register are inputted.  
     CONSTITUTION: An instruction decoder is divided into master instruction decoder 18 and slave instruction decoder 19 and decoder 18 is supplied with outputs of register 13 and atate control register 14. Decoder 19 is supplied with part 3a of outputs of register 13 and part 3b of outputs of decoder 18, and its outputs are led out together with decoding outputs 3c of decoder 18 by wired logic connections. In the arithmetic mode of a logical operation part, a common control signal uses control output part 3d only for the master instruction decoder of decoder 18 to hold control output 3c at level "H", thereby making a disconnection from decoder 19. Decoder 18 is supplied with outputs CCN0 and CCN1 of decoder 18 and lower two bits of instruction register 13 to assign the control mode of the logical operation part. Consequently, the number of signal lines of the instruction decoder part decreases and simplification is realized.

Abstract: PROBLEM TO BE SOLVED: To judge fastening state of a bolt in real time to reduce poor fastening by pressing a bolt by a socket, then reversely rotating the socket to detect that the bolt is put in the socket utilizing displacement of the socket by nearly socket hole depth. SOLUTION: When a nut runner 103 is reversely rotated, by the lead angle of the contact face of the screw thread of the male screw on the lowermost part of a bolt 106 and the female screw on the uppermost part of a fastened object 104, the bolt 106 is gradually elevated, and when the screw reaches a point beginning engagement, the screw suddenly falls by the length of one pitch. At this time, displacement in a fixed time becomes nearly equal to the length of one pitch of the screw, and the beginning point of screwing-in is detected. Because the position of surely meeting the thread ridge and the root of the male screw and the female screw can be detected as the beginning point of screwing-in, a trouble such as oblique insert of a bolt or seizure of screw thread as the most popular troubles in the case of automatic bolt fastening is not generated.

Abstract: PURPOSE:To detect a power voltage by utilizing a forward voltage of a PN junction element as a reference potential so as to utilize the MOS process as it is and using a detection voltage with less variation without an externally mounted component. CONSTITUTION:In selecting resistors 31, 32, a point where a potential V23 of a node 23 and a potential V33 of a node 33 crosses is set. For example, the potentials are crossed with a voltage VDD at nearly 3.6V and a differential amplifier circuit 40 receives the potential V23 of the node 23 and the potential V33 of the node 33. The two potentials are compared and when the potential V23 of the node 23 is lower, an L level and in case of a higher voltage, an H level is outputted respectively. Thus, the potential V53 of the output node 53 of a CMOS inverter 50 changes from an H level to an L level with the voltage VDD of nearly 3.6V. Then the detection voltage of the power voltage VDD is nearly 3.6V, and of the voltage VDD is lowered more than said value, the potential V53 of the node 53 changes from the L to the H level and the power supply voltage drop is detected.

Abstract: PROBLEM TO BE SOLVED: To enable the generating of an interpolated SBSYNC even when an SFSYNC is omitted by generating an interpolated block synchronizing signal based on count values of the LR signals of audio data when a block synchronizing signal is not detected. SOLUTION: A first counter 1 performs a counting operation by inputting an SFSYNC and also resets a count when a pre-interpolated SBSYNC is inputted. A second counter 2 performs a counting operation by inputting an LRCK indicating whether audio data being reproduced data are data for left (L) or data for right (R) and also resets a count when the pre-interpolated SBSYNC is inputted. An interpolated SBSYNC generating circuit 3 inputs a first count value from the counter 1 and a second count value from the second counter 2. Then, the circuit 3 generates an interpolated SBSYNC based on the first, second count values and when the SBSYNC is not detected, the circuit 3 outputs an pre-interpolated SBSYNC by using this SBSYNC.
