Title: Exposure method and exposure negative used therefor
Inventor: MORIUCHI NOBORU
IPC: G03F1/42
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To improve the alignment accuracy between an exposure original and an exposure object, by observing an exposure object-side alignment mark formed first on the exposure object through an exposure original side alignment mark, and then collating the two marks with each other. SOLUTION: A reticle 50, which is an exposure original, has a blank 51 formed in the shape of flat plate using quartz glass or the like, and an original image 52 and a reticle-side mark 55 as an exposure original side alignment mark are formed on a main surface of the blank 51. A wafer-side alignment mark formed on a wafer, which is an exposure object, is observed through the reticle-side mark 55, and the wafer-side alignment mark and the reticle-side mark 55 are collated with each other. Thus, since alignment between the reticle 50 and the wafer can be carried out directly, the accuracy of alignment can be significantly improved.

Title: Reaction cell for observing photochemical reaction
Inventor: AIZAWA TAKASHI
IPC: G01N21/75
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To enable a reaction intermediate generated by an excited light to be captured and observed with sufficient accuracy by positioning the inner surface of incident windows for the excited light in a light path or near the light path for an incident observation light, in a reaction cell for observing a photochemical reaction having each incident window for the excited light and an observation light. SOLUTION: A window 2 on which an observation light is incident and a window 3 from which the observation light goes out, both being formed in a cell body 1, are made of a platelike light-transmitting material, for example, sapphire. When the reaction cell is used, a light path for the observation light is formed between the windows 2, 3. An incident window 4 for a excited light is arranged in the notched part of the side wall of the cell body 1 in a direction orthogonal with the light path for the observed light, and an outgoing light window 5 is arranged in the notched part of the side wall of the cell body 1 opposite to the window 4. The incident window 4 for the excited light is formed of, for example, a stepped sapphire window or the like and its inner surface (a) is positioned in the light path for the observation light or near the light path.  Thus it is possible to certainly capture and observe a reaction intermediate which a photochemical reaction gives rise to.

IPC: B60L3/00
Filed: 1980-02-08
Abstract: PURPOSE: To enable driving operation of the electric car without any special resetting operation when supplied-power voltage is restored after the main circuit is interrupted by the fall of the supplied-power voltage of the electric car by providing a means for automatically resetting a supplied-power voltage detector.  
     CONSTITUTION: When the supplied-power voltage of the electric car falls below a prescribed value due to separation from a power line while the car is driven, the relay contact LVR of the supplied-power voltage detecting means is turned off and thereby a main-motor circuit is interrupted from the supplied-power circuit from a collector. Then, when the supplied-power voltage returns to the prescribed value, LVR is also turned on, and if a master controller MC is retained in the state "on", a driver can continue the control of the electric car by MC without any special operation. In the case when the supplied-power voltage is not restored to the prescribed value for a long time due to a trouble of a power-supply system and the like, the driver returns MC to the position of "off" for safety. When the voltage is restored to the prescribed value and MC is turned on by the driver, however, a relay coil R for resetting is actuated and the detecting means can be reset only by usual operation of MC without any special manual resetting operation for the supplied-power voltage detecting means.

IPC: G11B7/135
Filed: 1989-01-23
Abstract: PURPOSE:To attain a recording job with high density by setting a means between a laser light source and a condenser lens to reduce the transmittance of the crucial beams crossing at a point near the center of the section of a beam emitting from the laser light source. CONSTITUTION:The light beam emitting from a semiconductor laser 1 serving as a light source is collimated by a collimator lens 2 and undergoes the shaping of the beam form via a beam shaping prism 3. The shaped beam passes through a light intensity modulator 4 which reduces crucially the light beams in a state equivalent to a case where two sheets of light shielding bands 25 crossing to each other at a point near the center are set within a beam section. The beam passed through the modulator 4 passes through a beam splitter 5 and applied to a recording medium 7 in the form of a minute spot via a condenser lens 6. In a signal reproduction state the light reflected from a disk is led to a reproduction signal detecting system 8 via the splitter 5. Thus it is possible to improve the recording density in the circumferential direction of a track and the track density in the radius direction. Then the recording density of an optical disk is improved.
