Title: X-ray mask, manufacture therefor, and producing method of device using x-ray mask
Inventor: KATO HIDEO
IPC: G03F1/22
Filed: 1994-12-14
Abstract: PURPOSE: To obtain high X-ray absorbing material with a small thermal expansion coefficient and high dry-etching performance by a method wherein the absorber pattern, to be formed on a mask membrane, is formed by alloy containing tungsten and molybdenum. CONSTITUTION: A silicon substrate, which becomes an X-ray retaining frame 1, is connected to the frame 4, which is a reinforcement member, formed by heat-proof glass and the like. A SiN membrane film, which becomes an X-ray retaining film 2, is formed on the above-mentioned silicon substrate using a CVD method, and mask blanks are formed. On the X-ray retaining film 2, an X-ray absorber pattern, formed by alloy containing tungsten and molybdenum, is formed by dry-etching the Si substrate using the gas plasma mainly composed of sulphur carbon or sulphur fluoride gas. As a result, a high density X-ray absorber, having uniform composition and excellent surface properties, can be formed with a small stress.

Title: Hood storage device for convertible vehicle
Inventor: KODAMA YOSHINORI
IPC: B60J7/20
Filed: 1987-12-08
Abstract: PURPOSE:To facilitate the opening and closing of a cover and the handling of a hood and as well to facilitate the automation of the handling by making the cover displaceable between a closing position and an opening position, and by providing an opening and closing mechanism. CONSTITUTION:When a cover 10 is displaced from a close position to an open position, a storage section 20 is opened from the outboard side so that a hood 30 and a hood link mechanism 40 may move the outboard side of the cover 10, and accordingly, it is possible to prevent the hood 30, the hood link mechanism 40 and the cover 10 from crossing each other. As a result, it is possible to employ such a structure that the rear end part of the hood 30 is fixed to a vehicle body 2. With this arrangement, the locking of the hood 30 upon mounting can be made only at the front part of the hood, and therefore, the hood 30 can be locked at the driver's seat without the passenger alighting from the vehicle, thereby it is possible to facilitate the handling of the hood. Further, since the hood 30 and the hood link mechanism 40 are moved in only one direction, it is possible to simplify the structure and to facilitate the automation.

Title: Clock generator
Inventor: KOGA IZUMI
IPC: H03K5/08
Filed: 1987-12-08
Abstract: PURPOSE:To reduce phase jitter by varying the phase of the leading edge or the trailing edge of the output of a comparator based on a high-order one bit signal out of remaining bit signals in a digital signal not being added on a ROM. CONSTITUTION:Assuming the MSB of a signal SB as D28 and the LSB as D0, the ROM3 introduces signals D17-D28. And the bit signal of D16 in the signal SB is added on a D-type flip-flop(D-type FF)6, and the output of the D-type FF6 is added on an adder 8 via a resistor 12. The adder 8 introduces the output of a DAC4 via a capacitor 5 for DC cut, and the signal from the DAC4 is added on the signal from D-type FF6, then, added on an LPF10. Also, a ck signal is added from an oscillator 7 on the D-type FF6, which takes the coincidence between the signal outputted via the ROM3 and the DAC4 and the D16 corresponding to the signals D17-D28 based on the signals D17-D28 outputted from a latch. In such a way, it is possible to reduce the phase jitter of a clock signal.

Title: Method for separating and measuring cable conductor current and shield current from outer periphery of cable
Inventor: IKEDA TADAYOSHI
IPC: G01R31/08
Filed: 1989-11-30
Abstract: PURPOSE:To separate and measure a cable conductor current and a shield current from the outer periphery of a cable by forming pickup coils as a two-layer line-up winding structure and reciprocating the same. CONSTITUTION:A cable 1 is constituted by forming a metal sheath 5 and a plastic corrosionproof layer 6 on a cable core 4 mainly consisting of a conductor 2 and an insulator 3. A sensor coil 7 is directly wound around the surface of the layer 6 while a sensor coil 7' is wound around the layer 6 in a state crossing the axial direction of the conductor at a right angle in order to cross the magnetic field of the component in the axial direction of the conductor 2. The data of the magnitude and phase of the current flowing to the conduc tor 2 can be known on the basis of the current due to the voltage induced in the coil 7'. When the pickup coils are one-layer line-up winding, not only the magnetic flux of the compo nent in the axial direction but also the magnetic flux of the component in a theta-direction performs interlinking. When the coils are reciprocated, the magnetic flux crossing in the forward movement and the interlinking magnetic flux in the rearward movement becomes the same value and the codes thereof become reverse and only the magnetic flux of the component in the axial direction performs interlinking. Therefore, a conductor current and a sheath current can be accurately measured.
