Title: Working jig for semiconductor wafers
Inventor: KOSHIMURA TSUTOMU
IPC: B24B37/04
Filed: 1985-10-28
Abstract: PURPOSE:To detach wafers easily from a working jig by forming a groove in a semiconductor-wafer sticking region for the working jig. CONSTITUTION:A working jig 1 is heated to 80 deg.C or more by a hot plate or the vapor heat of a trichlorethylene solvent, and semiconductor wafers 6 are pasted onto a sticking surface 2, to which a groove 3 with a tapered section in 1mm upper-section width and 0.5mm lower-section width is shaped, through a melted sticking agent 5. Consequently, the working jig 1 to which the semiconductor wafers 6 are fixed is attached to a polishing machine, thus polishing the semiconductor wafers 6. The working jig 1 to which polishing is completed is heated by the hot plate or the vapor heat of trichlene, and the sticking agent 5 is melted and removed. Trichlene on the sticking surface 2 and in the groove 3 gradually evaporates and the effect of surface tension is eliminated, and the semiconductor wafers 6 are merely placed only on the sticking surface 2. Accordingly, the semiconductor wafers 6 are gripped by tweezers, etc., and can be detached easily.

Abstract: PURPOSE:To obtain a simple-structure and small-sized optical demultiplexer/ multiplexer whose number of parts is small, by providing a reference rod lens and an interference film filter on both sides of a parallel plane transmission plate. CONSTITUTION:When the light having wavelengths lambda1-lambda4 is made incident on a port I of a reference rod lens 151, the light having the wavelength lambda1 is demultiplexed and outputted from a port II of the reference rod lens 151, and the light having the wavelength lambda2 is demultiplexed and outputted from a port III of a rod lens 152, and the light having the wavelength lambda3 is demultiplexed and outputted from a port IV of a rod lens 153, and the light having the wavelength lambda4 is demultiplexed and outputted from a port V of a rod lens 154. When lights having wavelenfgths lambda1-lambda4 are made incident on ports II-V respectively, the multiplexed output having wavelengths lambda1-lambda4 is taken out from the port I. The number of rod lenses and interference film filters is increased or reduced to obtain the optical demultiplexer/multiplexer having an optional number of multiplexed or demultiplexed waves.

Title: Exposure apparatus
Inventor: NISHI TAKECHIKA
IPC: H01L21/027
Filed: 1986-10-13
Abstract: PURPOSE:To increase the precision of alignment and to improve a yield by a method wherein a shift from an alignment position to an exposure position is conducted not by moving equipment for alignment and a semiconductor wafer, but by moving a reticle, when a pattern of the reticle is exposed on the wafer. CONSTITUTION:A reticle 3 having a pattern 4 for transfer and a reticle mark M1 for alignment is disposed between a condenser lens 2 and a projection lens 5. Auxiliary lenses 21-23 for conjugating the reticle mark M1 and a mark M2 for alignment on a wafer 9 together with the projection lens 5, and further a relay lens 10, a mirror 14 and a collimator lens 15 out of components 10, 14, 15 and 16 of an optical system for focusing the reticle mark M1 and the wafer mark M2 on a CCD camera 17, are fitted integrally on a reticle stage 19A. Accordingly, factors of deterioration of precision, such as alignment and offset, can be reduced. Since the components 10, 14 and 15 of the optical system are also fixed in the relationship with the reticle stage 19A, the occurrence of dust is little, and thus a yield is improved.

Title: Magnetic card reader
Inventor: HIRANO YUJI
IPC: G11B19/00
Filed: 1990-09-14
Abstract: PURPOSE:To obviate the disengagement of a card from a transporting path and to decrease erroneous reading of data by providing an angle on a roller relative to the transporting direction of the card. CONSTITUTION:The roller 6 of the magnetic card reader 1 which transports the magnetic card 2 from the left to the right and stores the card in a stacking part 4 is mounted to incline from perpendicular with a traveling plane. Even if the card 2 is attempted to be transported along a card groove, there is the possibility that the card 2 is transported with the deviation in an upward direction according to the contact area of the roller 6 and the card 2 or the material quality of the roller 6 and the card 2 unless a member to cover the upper part of the card is installed on the magnetic card reader 1 side. The roller 6 is, thereupon, inclined in order to generate the force to hold down the card 2. The disengagement of the card from the groove is obviated in this way and the erroneous reading of the card is decreased.

Title: Servo pattern recorder and recording method using it
Inventor: NAKAGAWA MASAYOSHI
IPC: G11B21/10
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a servo pattern recorder and a recording method using it detecting its state just after a magnetic head collides with a foreign matter on a disk, detecting write-in abnormality in a servo pattern any time and rewriting on the disk. SOLUTION: When depositions adhere onto the disk 1, the depositions collide with the magnetic head 5a while writing the servo pattern. At a collision time, since vibration of a frequency band (nearly 350 kHz) higher than a normal frequency occurs, by loading an AE sensor 8 detecting only this frequency on a carriage 5, the presence of the collision is detected surely. Further, when the collision is detected, instantly, write-in operation is stopped, and by performing rewrite operation from a track position detecting the collision, the write-in work of the servo pattern is shortened.

After the electrode part is formed, silicide is formed by heat treatment. Thereafter, an Al layer 8 is formed as a surface electrode in a range broader than the electrode metal layer 7. Thus the SB semiconductor device is formed.

Title: Hot water supplier
Inventor: YASUDA TADAO
IPC: F24D17/00
Filed: 1987-09-28
Abstract: PURPOSE:To prevent hot water from being instantaneously supplied previously and to obtain excellent feeling of use by connecting a mixing water pipe from a mixing valve at the lower part of a hot water storage tank to the lower part of a hot water supply pipe. CONSTITUTION:When a water valve 5 is opened, water is introduced into a mixing valve 7 where the quantity of water allowed to flow to a tank supply water pipe 9 and that allowed to flow to a mixed water pipe 10, are distributed. When the water stop valve 5 is opened, an electric control part 17 acts to open a tank water supply pipe valve 15 and a mixed water pipe valve 16, and water flows. Water which has flowed to a tank supply water pipe 9 enters the lower part of a hot water storage tank 2, and hot water is pushed out from the upper part of the hot water storage tank 2 to a hot water supply pipe 12. On the other hand, water which has flowed to a mixed water pipe 10 is introduced to the lower part of the hot water supply pipe 12 and is mixed with hot water which has flowed from the upper part of the hot water supply pipe 12, and is heated to a suitable temperature and supplied through a cock 12. Every time the water stop valve 5 is opened, water from the mixed water pipe 10 surely flows to the cock in advance because water has a distance shorter than hot water flowing from the upper part. When the stop valve 5 is closed, the tank water supply pipe valve 15 and the mixed water pipe valve 16 are closed, no water within the hot water storage tank 2 is extracted through a cock 11.

Abstract: PURPOSE:To prevent heavy metal from separating from a stainless steel tube by forming a flow passage which flows perpendicularly to a magnetic field generated by magnetic field generating means and a flow passage for attenuating when microwave passes at the connector of a material gas inlet conduit and a metallic vessel. CONSTITUTION:At a coupling part of a material gas introducing passage 33 and a metallic vessel 39, the following two flow passages are formed: (A) a flow passage 40a wherein a material gas flows perpendicularly to a magnetic field generated by material gas magnetic field generating means; (B) a material gas flow passage having a size adequate for the attenuation of a microwave when said wave passes through a gap in an axial direction wherein the gap is formed with a ring-shape 41 having a length in the axial direction and said length is determined so that the gap length and the axial direction length are made allowable for the passage and the attenuation of the microwave. A plasma generated in a metal vessel cannot return along the passage perpendicular to the magnetic field, and the microwave is attenuated while passing through the ring-shaped gap, and the microwave entering into a material gas inlet conduit made of stainless steel tube does not substantially exist. Thus, the plasma is not generated in the conduit.
