Title: Device for detecting misregistration of mask and wafer
Inventor: TANAKA RYOJI
IPC: H01L21/027
Filed: 1990-04-20
Abstract: PURPOSE:To improve resolution by simple constitution by providing a pattern magnifying optical system with a flat-shaped objective having a high numerical aperture only in the direction perpendicular to the optical axes of reflection by the surfaces of the mask of illumination light and a wafer and parallel with the surfaces of the mask and the wafer. CONSTITUTION:A magnified image is formed by a flat objective 9 being arranged on the optical axes of regular reflection by the surfaces of the mask 4 of white light condensed by a lens 3 and a wafer 5, having a high numerical aperture only in the direction perpendicular to the optical axes and parallel with these surfaces and magnifying the images of a mask alignment mark 6 and a wafer alignment mark 7. Since these alignment marks 6, 7 are disposed on the same focal surface by the objective 9 from the oblique direction the images of these alignment marks 6, 7 can be observed simultaneously even when the objective 9 having the high numerical aperture and shallow focal depth is used. Since the objective 9 has a large numerical aperture regarding the direction of the detection of positional displacement, the objective 9 has high resolution, and has low resolution in the direction at a right angle to said direction, thus optically levelling picture data by a TV camera 11.

Title: Flat tire detecting method for wheel
Inventor: IWABORI MICHIO
IPC: B61K9/12
Filed: 1995-04-28
Abstract: PURPOSE: To easily and effectively detect the occurrence of the flat time a wheel from a vehicle without personal difference. CONSTITUTION: The maximum value of wheel speeds is selected by a rotating speed maximum value selector 22 during braking drive, and if it is a predetermined value, or more by a first comparator 23, a flat occurrence detecting operation is performed. In this case, the substantially zero wheel is detected by a second comparator, the continuing time of the speed zero state is calculated by a period calculator, and when this exceeds the value set by a period setter 30, a period discriminator judges the flat the occurrence. Or, the distance moved by the vehicle during the period where the specific wheel continues the speed zero state is estimated by a traveling distance estimating calculator, and if the distance exceeds the value set by a traveling distance setter, the discriminator judges the flat tire occurrence.  Incidentally, flat occurrence concerned data is stored by an OR element for trigger, a memory and a clock, or the number of times of flat tire occurrence after the wheel is ground is counted by a counter and a reset signal.

Title: Semiconductor integrated circuit device using complementary mos circuit
Inventor: KANO YASUO
IPC: H01L21/8238
Filed: 1989-04-25
Abstract: PURPOSE:To alleviate an electric field concentration, to enhance the breakdown voltage resistance of a wiring film and to increase a current capacity by rounding the end shape of metal wirings in conductive contact with a diffused layer resistor of an input side, and removing a metal edge. CONSTITUTION:The ends of aluminum wirings 8, 9 in conductive contact with both ends of a diffuse layer resistor 4 as a P-well formed on a N-type isolated insular region 10 are formed as round ends 8b, 9b, and the contact holes are formed not as square shape but round shape contact holes 4c, 4d. Thus, since no edge exists at the junctions between the resistor 4 and the wirings 8, 9, even if an overvoltage is applied to an input terminal 3, there is no electric field concentration, but there is a uniform electric field distribution. Thus, the breakdown voltage resistance of a wiring film is enhanced, and its current capacity is also increased.

Title: Rush current preventing circuit
Inventor: SOGOU TOSHIYUKI
IPC: H02M3/335
Filed: 1981-07-08
Abstract: PURPOSE:To prevent rush current and to perform stable operation, by flowing an input current from a protective resistance to a solid-state relay with switching when a secondary side output voltage reaches a specified voltage or more. CONSTITUTION:When an AC power supply A is turned on, an output voltage B appeared at secondary output terminals 16 and 16' does not rise, and then the inout current of the power supply A flows to a protective resistor 5. Further, after a prescribed time, the voltage B required for starting the operation of a power supply controlling circuit reaches a normal value and a drive circuit is operative to turn on a solid-state relay SSR11. Then, the input current of the power supply A does not flow through the resistor 5 but through the SSR11 only. Thus, heating of the resistor 5, unnecessary power loss and unstable power supply can be prevented. Through constitution like this, with the SSR11 turned off, since a time of the input current flowing to the resistor 5 is a time when the voltage B rises, the heating of the resistor 5 is minimized, allowing to completely prevent rush current.

Filed: 1991-05-13
Abstract: PURPOSE:To obtain the iC card reader/writer which is not damaged even if a metallic plate is inserted instead of an iC card by inserting a resistance for protecting a control part at the time of short circuit of a contact, into a power source line and a signal line. CONSTITUTION:In a power source line VPP and a signal line (in this example, a clock line CLK and a serial input/out line i/O) in lead wires 3 for connecting an iC card reader/writer control part 1 and its opposed iC card contact part 2, a resistance 4 is inserted, respectively. In this case, as for a value of the resistance 4, a resistance value being as large as possible is selected within a range in which an iC card can be operated normally, in the case the iC card inserted from the outside comes into contact normally with the contact part 2. In such a way, even if a metallic plate is short-circuited between a power source line VPP and a ground, or between the signal line and a ground, the control part 1 of the iC card reader/writer is protected by a current limiting effect by the resistance 4.

IPC: H03D1/22
Filed: 1989-04-25
Abstract: PURPOSE:To secure a considerably large dynamic range (about 90dB) by logorithm-converting an input amplitude and separately detecting the amplitude and a phase. CONSTITUTION:A logorithm amplifier 1 logorithm-converts the amplitude of a reception modulation signal which has been band-limited and is outputted.

On the other hand, the output of the logorithm amplifier 1 is limited to a constant amplitude by a limiter 4, and a phase detector 5 detects a phase difference with a reference signal from a reference signal generator 6. The amplitude and the phase detected by the A/D converter 3 and the phase detector 5 are inputted to an arithmetic processing circuit 7. It accumulates the signal of one block (packet) and converts it into a linear amplitude with the maximum value as reference.

The direction of the birefringence of the element 102 and 102' which operate as the wavelength plates are set properly. Consequently, the polarization control range is unlimited and polarization control is performed for variation of optional incident polarized light.
