Title: Aligning method
Inventor: SUZUKI NOBUMASA
IPC: H01L21/027
Filed: 1983-10-31
Abstract: PURPOSE:To enable to align two bodies, a mask and a wafer, with higher precision by a method wherein parts, where light is not transmitted, are formed on the mask, while photoconducting parts and photoconductive films are formed on the wafer and the respective resistance value of the photoconductive films is measured. CONSTITUTION:Alignment marks 6a and 6b, which have been respectively provided with a light- shielding part in the x-direction and the y-direction, are formed on a mask 2, and their positions are respectively positioned corresponding to the positions of the alignment marks 7a and 7b of a wafer 4. In the detecting part in the y-direction of the alignment mark 7a on the wafer 4, conductive films 70a-70c for electrode and extendedly formed in the x-direction and each of the one ends A-C of the conductive films 70a-70c is connected to a resistance meter 8. Photoconductive films 71a and 71b are formed on the wafer 4. In this constitution, in case the deviation of position in the y-direction between the mask 2 and the wafer 4 is detected, the resistance value between the a and the B (or between the B and the C) is first measured at the non-lighting time of lighting system 1. Then, when the resistance value at the same place is measured at the lighting time of the system 1, the deviation of position in the y- direction can be found out. Similarly, the respective deviation of position in the x-direction and the theta direction can be also found out by performing the same way.

Title: Soft start switch performing voltage control and current limitation
Inventor: GOERKE ULRICH B
IPC: G05F1/40
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a soft start switch that has a current limitation function without using a current detection resistance. SOLUTION: This soft start switch does not need a current detection resistance by utilizing transconductance of a MOSFET 10. A feedback circuit is constructed by connecting an outputting part of an operational amplifier 20 to a gate 12 of the MOSFET and connecting an inverted inputting part 24 of the operational amplifier to an outputting part 50 of the soft start switch via a voltage dividing circuits 142 and 144. Soft start of a load 55 is executed when a voltage which is supplied to a non inverted inputting part 22 of the operational amplifier by a 1st RC circuit triggers the operational amplifier and gradually increases the output voltage of the operational amplifier from zero volt to a prescribed reference voltage.  A current limiting means consists of a comparator circuit 110 and voltage dividing circuits 170a, 170b, 180a and 180b and limits current by making the MOSFET 10 an off state.

IPC: G01C3/06
Filed: 1989-08-04
Abstract: PURPOSE:To expand the distance measurement range to a long distance by providing a gain control circuit which controls the resistance value of an analog circuit with the output of one of detectors so that the output of one detector becomes constant. CONSTITUTION:When an object of distance measurement is close and the signal of a position detecting element 24 is large, the outputs of detecting circuits 6 and 7 become large, the collector currents of transistors(Tr) Q13 and Q14 become large, and the collector-emitter resistances of Trs Q1-Q4 become small; and the gains of amplifiers 2 and 3 become small, and consequently the outputs of the circuits 6 and 7 decrease. When the object of distance measurement is at a distance and the signal of the element 24 is small, on the other hand, the outputs of the circuits 6 and 7 become small, the collector currents of the Trs Q13 and Q14 become small, and the collector-emitter resistances of the Trs Q1-Q4 increases; and the gains of the amplifiers 2 and 3 become large, and consequently the outputs of the circuits 6 and 7 increase.

Abstract: PURPOSE:To form a digital FM modulation signal without using an ROM and deteriorating the S/N by using a comparator circuit comparing an output data of a digital integration circuit while using a phase data of a sinusoidal wave as a reference value and an encoder. CONSTITUTION:An output data word of a digital integration circuit 5 with an output signal of 1 word N-bit is fed to 2N-1 sets of digital comparator circuits 8(1)-8(2N-1). Data words R(1), R(2)-R(2N-1) representing 2N-1 sets of levels, e.g., increased linearly and sequentially are fed to the other input terminal of the comparator circuit as reference values respectively. The comparison output is ''1'' or ''0'' depending on the difference between the reference value and the integration output data in each comparator circuit. Thus, the level of the integration output data, i.e., the phase position of a sinusoidal wave is represented by the comparison output. Then 225 sets of outputs of each comparator circuit are fed to an encoder 9. The level of the sinusoidal wave at the phase position represented by the comparison output is encoded from the comparison output at the encoder 9.

IPC: H01S3/0915
Filed: 1990-08-01
Abstract: PURPOSE:To improve amplification efficiency of 1.3mum band by considering both ends of an optical fiber which is an amplifying medium to a counterplan for preventing the reflection of 1.3mum light and 1.05mum light. CONSTITUTION:Both ends of the optical fiber (neodymium doped fluoride optical fiber) 1 for the amplifying medium are connected with 1.05/1.3 WDM couplers 3 which are formed of quartz glass and are butt connected to the optical fiber 1 for the amplifying medium. A matching liquid 3 is put therebetween. The refractive index of the quartz fiber is about 1.468 and the refractive index of the fluoride fiber is about 1.50 and, therefore, the matching liquid 3 having about 1.485 refractive index approximate to the intermediate value of both is more preferable in order to decrease the end face reflection at the fiber connecting points. The 1.05mum light reflected and amplified at both end faces of the amplifying medium is suppressed in this way, by which the amplification efficiency of 1.3mum is improved as well.
