Title: Detecting head of metal detector
Inventor: YOKOTA KYOICHI
IPC: G01V3/11
Filed: 1989-12-12
Abstract: PURPOSE:To prevent malfunction due to an effect of noise from a surrounding apparatus by providing a yoke so that a magnetic circuit wherein magnetostatic fields generated by permanent magnets pass through two reception coils is constructed. CONSTITUTION:Products W packed by packages A are passed one by one by a conveyor 20. When a metal exists in the product W, changes occur in magnetostatic fields generated by permanent magnets 13, 13... when the product passes by reception coils 12a and 12b. Therefore the number of magnetic fluxes traversing the coils 12a and 12b changes, induced voltages occur in the coils 12a and 12b and a differential voltage between them occurs. The existence of the metal in the product W is detected from this differential voltage. Since a magnetic circuit of which the gap is a hollow part 11a is constructed by a yoke 14, a leakage flux of a detecting head 10 to the outside lessens remarkably in this detection. Consequently false detection due to external noise decreases remarkably, while the magnetic fluxes near the coils 12a and 12b become strong. As the result, even the detection of a very minute metal is enabled.

Title: Heat treating method of ii-iv compd. semiconductor crystal
Inventor: SANO MICHIHIRO
IPC: C30B33/04
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To improve the yield by preventing component elements of a II-IV compd. semiconductor crystal from dropping to result in a rough surface of the crystal due to a heat treating step to grow the crystal by the conventional MBE method. SOLUTION: At heating of a II-IV compd., ZnSe substrate, a Zn and Se beams are applied, starting from a point S1, Z1 to a stop point S2, Z2 based on the vapor pressures of the component elements whereby Zn and Se dropping due to the heating are compensated to result in that no oxide film exists on the surface of the substrate obtained after the end of the heat treatment but a flat crystal surface is obtained without roughening it.

Title: Software registering system
Inventor: FUJIOKA TOSHIYUKI
IPC: G06F9/06
Filed: 1988-12-20
Abstract: PURPOSE:To make it unnecessary to determine what is to be used as an optional software at the time of registering an operating system (OS) in a system by dividing load module library files into two files, i.e. a file to be used for software to be delivered together with the OS and a file to be used for the optional software. CONSTITUTION:In the case of registering the OS, the load module library file 3 to be used for the software delivered together with the OS is secured at a fixed capacity and a load module is registered in the file 3. In the case of registering an optional software, what is used as the optional software is determined, the capacity of the load module file 4 to be used for the optional software is calculated, the file is secured, and the optional software is registered in the file. Thereby, it is unnecessary to determine what is registered as an optional software at the time of registering the OS in the system.

Title: Method for transmitting document image to client work station
Inventor: JAMES V MAHONY
IPC: G06T11/60
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a method for transmitting a document image stored in a memory at a server work station to a client work station. SOLUTION: The progressive transmission of document image data is executed through two steps. During the first step of transmission, steps 2006 and 2008 are executed. In the step 2006, a layout object in a request page image identified in a step 2004 is transmitted with a first, namely, high resolution to the client work station. Next, in the step 2008, a layout object in a request page image, which is not identified in the step 2004, is transmitted with a second, namely, low resolution to the client work station. When image data are received, the client work station formats the transmitted image data and copies an original document image.

Title: Josephson junction device and manufacture thereof
Inventor: KAWAHARA NOBUAKI
IPC: H01L39/22
Filed: 1991-12-06
Abstract: PURPOSE:To constitute a Josephson junction device with no use of Pr so as not to spoil electrode superconductivity by making a RBa2Cu4O8 oxide superconductor into first and second electrodes and by sandwiching a RBa2Cu4Oy oxide as the intermediate layer between the first and second electrodes. CONSTITUTION:An insulating substrate 1 is overlaid with a YBa2Cu4O8 superconductor film 2 as a first electrode. This film 2 has a Tc of 80K. It is overlaid with a YBa2Cu3O4 non-superconducting film as an intermediate layer 3 so that the oxygen amount can decrease, and further with a superconducting YBa2Cu4O8 film 4 as a second electrode. In this constitution, the YBa2Cu3Ox film of the intermediate layer 3 shows no superconductivity because of having a small oxygen amount and being semiconductive regarding a temperature change in electric resistance. Therefore, it functions as the intermediate layer of a Josephson junction and may not be of laminated type, but of planar type in layer constitution.

Title: Gate cutting device
Inventor: TAKEI KAZUYOSHI
IPC: B29C45/38
Filed: 1988-12-22
Abstract: PURPOSE:To deal with a work in close proximity with a gate by vibrating a pipe both ways by means of a rocking cylinder, folding and cutting the gate securely and eliminating the cylinder leaning the pipe in the right angled direction and making a device compact. CONSTITUTION:A vertical cylinder 35 is withdrawn, and the a gate constituting unit 1 is leaned inwardly making a rocking shaft 6 as a support by driving ahead a rocking cylinder 22 to fold a gate 32 of a work 20.

Title: Optical information reader
Inventor: OYAMA TADATAKA
IPC: G11B7/09
Filed: 1987-12-23
Abstract: PURPOSE:To eliminate an off-center and to suppress the fluctuation of a tracking error signal amplitude at minimum in the inner and outer circumference of a disk by providing a holding mechanism along the shaft direction of a chilled shaft to hold an optical block, which is held by a guide, to be parallelly movable. CONSTITUTION:A tilt mechanism, which has a sending mechanism to hold an optical system 2, is wholly moved parallelly in the shaft direction of a tilt supporting point 12. Namely, by executing operation to push one of the tilt supporting points 12, which are provided in the both sides of a tilt member with a screw 14 (at such a time, the other supporting point 12 pulls out the screw 14), the tilt mechanism is wholly moved parallelly in the shaft direction of the tilt supporting point 12. Accordingly, a straight line to connect a point, where the optical axis of a reading optical system crosses in the inner circumference of a disk 4, and a point, where the optical axis of the reading optical system 2 crosses in the outer circumference of the disk 4, is adjusted so as to pass through the center of the disk 4. Thus, since the influence of the curvature of a disk track is not received when the reading optical system 2 reads the information of the disk 4, the degradation of an RF signal and a tracking signal, etc., can be prevented.
