Title: Subtracting circuit
Inventor: YOSHIDA NAOMI
IPC: G06G7/14
Filed: 1987-02-27
Abstract: PURPOSE:To reduce an error signal to improve the precision of a subtracting circuit by inserting plural differential amplifiers in the subtracting circuit and cascading them. CONSTITUTION:Differential amplifiers 3, 6, and 9 have input terminals 10 and 11 and output terminals 12 and 13. The input signal of the terminal 10 is outputted with the same phase from the terminal 12 and is outputted with the opposite phase from the terminal 13, and the input signal of the terminal 11 is outputted with the opposite phase from the terminal 12 and is outputted with the same phase from the terminal 13. These amplifiers are so cascaded that the output signal of the terminal 12 of the amplifier 3 is connected to the terminal 10 of the amplifier 6 and the output signal of the terminal 13 is inputted to the terminal 11. By this constitution, the error in the output of the amplifier 6 is reduced by a component corresponding to the product of sums of error even if the input signal of the amplifier 3 is leaked to the output side with the same phase or the gain of the in-phase output of the amplifier and that of the anti-phase output of the amplifier 6 are different from each other. Thus, the error signal is reduced to perform subtraction with a high precision.

Title: Semiconductor laser element
Inventor: YAMAMOTO SABUROU
IPC: H01S5/20
Filed: 1981-03-23
Abstract: PURPOSE:To prevent the deterioration of the characteristics of a semiconductor laser element due to irregular segregation of impurity by doping impurities of the same type in an active layer and a crystalline layer bonded to the active layer at the substrate side. CONSTITUTION:An n type clad layer 2' is produced by a liquid phase epitaxial growth method on an n type GaAs substrate 1, and an active layer 3' doped with the same impurity as the layer 2' is accumulated on the layer 2'. When the impurity constitution is thus set, even if the impurity from the layer 2' is mixed to the layer 3', the irregularity can be eliminated.

Title: Distribution type pressure sensor
Inventor: KATANO TOMONORI
IPC: G01L1/22
Filed: 1989-02-27
Abstract: PURPOSE:To make interference due to a lateral load small by providing two couples of series-connected active gauges and constituting a Wheatstone bridge circuit between the two active gauges and two dummy gauge. CONSTITUTION:Active gauges 2B1 - 2B2 are formed on the top surface 2D of a single-crystal Si plate 2 as semiconductor strain gauges which detect a load placed on a load placing part 3 as strain. Further, a dummy gauge 2E is formed at the peripheral part of the plate 2 where no strain is generated. The gauges 2B1 - 2B4 and gauge 2E are incorporated in the bridge circuit so the gauge 2B1 and 2B2, and 2B3 and 2B4 are in couples, so that an output voltage e0 is produced between output terminals. Consequently, even if the application part 3 becomes eccentric, the resistance value variations of the semiconductor strain gauges compensate one another, so an interference output due to a lateral load can be suppressed.

Title: Fabrication of thin film solar cell
Inventor: UMEMOTO TETSUMASA
IPC: H01L31/04
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To perform pattering of a backside reflective electrode layer well using laser light by irradiating the backside reflective electrode layer with the fourth harmonic of Nd-YAG laser light thereby patterning the backside reflective electrode layer. SOLUTION: The fourth harmonic 11 of Nd-YAG laser light is irradiated from the backside reflective metal film layer 8 side. The layer 8 is irradiated normally with the fourth harmonic of a Q switch oscillation Nd-YAG laser. The number of scanning time is only one. Consequently, Ag of the layer 8 and ZnO of a backside transparent conductive layer 7 are removed and a groove 10 for scribing a backside reflective electrode layer 9 is formed. Since the evaporation energy of Ag-Ag is 2.64eV/atom and the energy of the fourth harmonic is 4.66eV, the laser light can unbond and evaporate Ag directly. According to the method, thermal damage on an amorphous semiconductor photoelectric conversion layer 5 can be reduced significantly and patterning can be effected well using laser light.
