Title: Semiconductor laser
Inventor: KONNO KUNIAKI
IPC: H01S5/00
Filed: 1987-02-25
Abstract: PURPOSE:To avoid short circuits caused by a high reflectivity film between two ohmic electrodes completely, by performing chamfering at a side, where the surface of the ohmic electrode on the side of a substrate is contacted with the end surface of a resonator, in which the high reflectivity film is formed. CONSTITUTION:The vicinity of a side, where an ohmic electrode surface 5 on the side of a substrate is contacted with the end surface of a resonator, in which a high reflectivity film 10 is formed, is chamfered. Even if a short- circuit path is formed between the ohmic electrode film 5 on the substrate side and an ohmic electrode film 6 on the side of a cap layer, the short circuit path can be released by removing a part of the high reflectivity film 10. Therefore, the intrinsic operation of a semiconductor laser can be stabilized. When the chamfered area is too large in chamfering, damages such as cracks might be yielded at the end surface of the resonator. Therefore, it is a matter of course to pay sufficient attention.

IPC: A61B10/00
Filed: 1988-02-23
Abstract: PURPOSE:To take an image at a high S/N ratio without specifying a region, by providing a decoupling coil having the almost same characteristic as a receiving coil in close vicinity to the receiving coil and performing control so as to cancel the induced voltage of the receiving coil and that of the decoupling coil each other out at the time of the transmission of an exciting high frequency pulse. CONSTITUTION:Since a receiving coil 1 and a decoupling coil 2 are almost same in characteristics and close vicinity to each other, voltage sources e1, e2 become induced voltages same in magnitude. Therefore, the current i1 flowing to the receiving coil 1 from the voltage source e1 and the current i2 flowing to the decoupling coil 2 from the voltage source e2 become same in magnitude. When an exciting high frequency pulse is transmitted, a closed circuit is formed, and the current i1 flowing to the receiving coil 1 from the voltage source e1 and the current i2 flowing to the decoupling coil 2 from the voltage source e2 are negated each other and no induced current flows to the receiving coil 1 and the decoupling coil 2. Therefore, even when a receiving coil apparatus is placed at any region within a magnetic field due to an exciting high frequency pulse, an image can be taken at a high S/N ratio.

Abstract: PURPOSE: To correctly reproduce data by negating the difference even when there is difference between the frequencies of the respective parts in a transmitter-receivers. CONSTITUTION: When there is difference between the frequencies of the respective parts such as a local oscillation frequency in the transmitter-receiver, a DC part corresponding to the difference is loaded on a wave detection signal Sa to cause malfunction. Then, an offset voltage detection part 34a detects the DC part included in the wave detection signal Sa as offset voltage OFV and a subtraction part 34b subtracts the offset voltage from the wave detection signal Sa to output so that binarization data is outputted based on the output of the subtraction part. On the other hand, an AD converter 51 digital-converts the wave detection signal Sa and an average value arithmetic part 52 calculates the average value of the output of the AD converter to output the average value as the DC offset voltage value OFV of the wave detection signal.  Then a subtraction circuit 34d calculates difference between the digital wave detection output and the offset value to output a data column from a highest-order bit.

IPC: F24J2/48
Filed: 1981-03-20
Abstract: PURPOSE:To enable a latent heat accumulating material in the titled device to accumulate heat efficiently by a method wherein heat collecting medium circulation passages are formed within the latent heat accumulating material. CONSTITUTION:When sunlight is converted into heat energy by a heat collecting body 4 through a transparent plate 2 and an inner film 3, the heat medium circulating passages P1a, P2a,... which are located adjacent a heat collecting body and the heat accumulating material 5 in the passage are first heated so that the spacific gravity of the heat medium is reduced. The heat medium then transfers to an upper header 7a and the heat medium which is not yet heated is in turn supplied to the heat medium accumulating passages P1a, P2a,... from a lower header 7b so as to be heated. Thus, when the above condition is kept continued, the heated heat medium which has been transferred to the upper header 7a is forced to enter the heat medium circulation passages P1b, P2b,... so that it transfers heat to the heat accumulating material adjacent thereto while the heat medium itself is cooled.
