Title: Position detector and pattern forming apparatus using the same
Inventor: KATAGIRI SOUICHI
IPC: G03F9/00
Filed: 1991-10-15
Abstract: PURPOSE:To enhance an accuracy by providing position detecting means integrated with an interferometer for detecting a position, sample holding means, position measuring means, sample finely moving means, exposure/plotting means and mask or plotted data formed with a desired pattern. CONSTITUTION:Diffracted lights 8, 9 when a grating mark 1 on a wafer is irradiated with a monochromatic light source 11 are introduced to a polarizing beam splitter 4 through an objective lens 2. A P wave of the + primary diffracted light 8 is converted into an S wave through a lambda/4 phase plate 5a, a corner cube 6 and again the plate 5a. Since the light 8 becomes the S wave, it is converted to the P wave through the splitter 4, a lambda/4 phase plate 5b, a mirror 7 and again the plate 5b and fed to a photoelectric converter 12a through a polarizing plate 10a. An S wave 9b of the-primary diffracted light 9 is superposed on a primary diffracted light 8a, and output from the splitter 4. Thus, the position of the mark 1 can be accurately measured, and its size can be decreased.

Title: Recorder
Inventor: TAKUBO YONEJI
IPC: G02F1/055
Filed: 1984-12-18
Abstract: PURPOSE:To make the direct recording, displaying, holding and rewriting of information possible by constituting a recorder of ferroelectric plate-shaped light transmittable ceramics provided with transparent electrodes on both surfaces and having a light scattering electrooptic effect and a heat generator which can apply locally heat to the plate-shaped light transmittable ceramics. CONSTITUTION:A PLZT plate 1 is polarized and the transmittivity thereof changes and the polarization state changes as well if an electric field exceeding a certain specified electric field is applied to said plate upon impression of a voltage between the transparent electrodes 2 formed on both surfaces of the PLZT plate 1 having the light scattering electrooptic effect. The polarization state of the linearly polarized light past a polarizing plate 6 changes during the transmission through the PLZT plate 1 when light is irradiated on the plate 6 from the rear thereof. The linearly polarized light in the direction coinciding with the axis of polarization of an analyzing plate is then transmitted through said plate. The direct writing of optional information on the PLZT plate 1 is made possible by moving a thermal head 3 by an X-Y movable part 4 and applying locally the heat to the PLZT plate 1 by a driving circuit 5 to change successively the transmittivity. The written information is erased by repolarization when the voltage is impressed between the transparent electrodes 2 provided on the front and rear of the PLZT plate 1.

Title: Manufacture of rubber seat ring for valve
Inventor: SHIMADA KIICHI
IPC: B32B25/08
Filed: 1986-11-11
Abstract: PURPOSE:To make is possible to obtain a thick Teflon coating and, in addition, obtain a rubber ring for valve having uniform thickness by a method wherein a Teflon outer surface covering tube is fitted onto a tensioned rubber elastic seating material and, after the tension is relieved, both ends of the seating material are joined to each other in order to make it into an annular form. CONSTITUTION:The outer diameter of an elastic seating material 10 is reduced by applying tension in its longer direction so as to become smaller than the inner diameter of a Teflon outer surface covering tube 20. In the state as mentioned above, the outer surface covering tube 20 is fitted onto the peripheral surface of the elastic seating material 10. After that, the tension applied to the elastic seating material 10 is relieved. As a result, the outer diameter of the elastic seating material 10 restores its initial state due to the elasticity of rubber and consequently the Teflon outer surface covering tube 10 tightly fits onto the peripheral surface of the elastic seating material 10. Next, parts in which built-in fittings 11 are imbedded are removed and adhesive 60 is applied to both ends of the material and finally both the ends are thermowelded with a heater 70 so as to join them into an annular form. Thus, a rubber seat ring for valve is manufactured.

Title: Power seat for vehicle
Inventor: SATO KAZUHIKO
IPC: B60N2/90
Filed: 1985-11-27
Abstract: PURPOSE:To secure a wide riding space in front of a seat and make people smoothable to get in a car, by driving the seat to the extend of being reached to the rear end automatically at that point the specified time elapses, in the case where a rider alights from the car and the seat is left unoccupied. CONSTITUTION:When a rider comes off a seat at the specified time t1 and the seat is left unoccupied, a seat switch 8 is turned off. At this time an ON delay timer DT gets operating, but there is no output till delay time T elapses. Therefore, since an OR gate OR and an AND gate A4 in a vacant-seat automatic backward device BB are not conducted each, a transistor Tr2 is also maintains its OFF state whereby stoppage of a motor 5 is continued. The delay time T elapses at time t2, an ON delay timer D produces its output, so that an AND gate A3, an OR gate OR1 and the AND gate A4 are conducted with one another. In consequence, a relay contact ry2 is selected to the side of a terminal s1, and a motor 1 is reversed, thereby having the seat retracted.

Title: Chip fuse
Inventor: FUJIMORI HIROYUKI
IPC: H01H85/06
Filed: 1994-10-31
Abstract: PURPOSE: To sufficiently fill glass in a fusible part, and provide a stable insulating characteristic by forming an extremely narrow fusible part of a fuse conductor film so that a central width becomes wide and both end sides become narrow. CONSTITUTION: An extremely narrow fusible part 3a whose width is nonuniform is formed in a central part of a fuse conductor film 3, and the part 3a is formed so that a width of a central part becomes wide and its width becomes narrow as it proceeds to both ends. When an overcurrent flows in the film 3, a heating action of Joule heat is generated in the film 3, and since the heat exceeds a melting temperature of the film 3, the film 3 is fused. In this case, though heating concentrates in a central part by a shape of the part 3a of the film 3, since a heating action more sufficient than usual is generated even in a part separate from the center, a width of a fused fusible groove can be sufficiently widened.  Therefore, a glass component constituting a glass covering layer 4 is sufficiently softened and flows in the fusible groove, and since high insulating performance can be secured, generation of an arc or the like can be prevented.
