Title: Manufacture of optical information recording medium
Inventor: SAKAGAMI YOSHITAKA
IPC: G11B7/26
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To suppress interface peeling off between a dielectric layer and a recording layer which may occur by humidity test after the initial stage crystallization of the recording layer is executed in a phase transition type optical disk. SOLUTION: Regarding a resin substrate before a multilayer film composed of the recording layer and the dielectric layer is formed, moisture in the resin substrate is previously separated by executing either (1) a stage for irradiating infrared rays or ultravillet rays or (2) a stage for exposing to a atmosphere having an atmospheric pressure of <=1×10-3 Torr. Thus, peeling off between the recording layer and the dielectric layer is suppressed by eliminating moisture from the resin substrate.

Title: Device and method for inspecting off-track characteristic of mr head
Inventor: MUKOHARA NORIAKI
IPC: G11B5/39
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To shorten an inspecting time and to improve the inspecting efficiency of a magnetic head by erasing data in a spiral form by an inductive head, writing test data and reading the data in a spiral scanning manner by an MR head. SOLUTION: A disk 20 is rotated, an erasing current is supplied to an inductive head 1a and, moving in a direction R, data within the range of a track TRS is erased in a spiral form and then test data is written. Then, by an MR head 1b, the test data is read in a spiral scanning manner by a proper sensing current. Further, an average value of one rotation among positive and negative side peaks of read signals is detected and stored together with the radial position data of the disk in a memory circuit. Since such spiral scanning reading is performed continuously, reading during the step movement of the MR head 1b is not interrupted. Thus, an inspecting time is shortened and, by combining the inductive head with the MR head, the inspecting efficiency of a magnetic head is improved.

Title: Production of quartz glass crucible for pulling up high-purity single crystal silicon
Inventor: WATABE HIROYUKI
IPC: C03B20/00
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a crucible hardly crystallizable even at the time of use at high temperatures by using a quartz glass plate having respective contents or below of Al, Fe, Na, K, Li and Ca and a specific value or below of the total content of other impurities as a shielding material when melting a raw material quartz sand according to a rotary mold method. SOLUTION: A quartz glass plate having <=20 ppm Al content, <=2 ppm Fe content, <=2 ppm respective contents of Na, K, Li and Ca and <=20 ppm total content of other impurities is used as a shielding material. A brown mark found after completing the pulling up is an oxygen-deficient cristobalite which is reduced by reaction with molten silicon and recombined to undergo the transition. The planar devitrification hardly causes the deterioration in decontamination factor(DF) ratio; however, the three-dimensional devitrification makes cristobalite peel and mix in a silicon melt to cause the formation of polycrystals due to Na, K, etc. The apparatus for producing the crucible is composed of a rotary mold 1, a raw material powder 2, the shielding material 3 and carbon electrodes 4. The contamination by Na, etc. frequently occurs in the shielding material 3.

SOLUTION: A base plate 4 around a titanium-clad steel plate is welded to a steel structure 1. When a titanium-clad steel plate 2 is thin, a titanium joining material 3 of the titanium-clad steel material 2 is cut back in advance in the vicinity of a welded part 6 of a lining end face and a welded part 7 between steels of the titanium-clad steel plates in order to prevent the brittlenss of a clad interface. A missed part 5 of titanium joining material is friction- cladded by welding to form a continuous clad part 8. To effect the covering by the friction cladding by welding, a metallic rod is rotated and pressed against the steel plate, and horizontally moved in the welding direction of the welded part 7. The metallic rod is elevated when the cladding by welding is completed.

Title: Position registration system
Inventor: FUNEKAWA KIMITOSHI
IPC: H04W60/00
Filed: 1991-08-02
Abstract: PURPOSE:To obtain the system updating the position registration not inducing the complexion of a line by transmitting the position registration number of the traveling point of the transportation from the base station in the transportation. CONSTITUTION:In a means of transportation (train)1, a base station 2 taking the inside of the transportation as a service area is provided. The base station 2 uses two types of radio waves 3 and 4 to send the position registration number for the position registration to a portable station inside the train 1. Before the movement of the train 1, the base station 2 sends the same position registration number as a position registration area 5 near the place where the train 1 was before the movement. When the train 1 moves to reach a position registration area 6 of the movement destination, the base station 2 sends the same position registration number as the area 6 before passengers getting on and off. Thus, the updatings of the position registration number of most portable stations in the train 1 are finished at the arrival point, preventing batch position registration updating accompanied by the passengers getting on and off.

Filed: 1988-08-31
Abstract: PURPOSE:To enhance the extent of volumetric efficiency by installing a cylinder, provided with a circular cam storage chamber being superposed on a compression space, and a swing can partitioning this compression space into both high and low pressure chambers, respectively. CONSTITUTION:Since a cam storage chamber 30 is formed into circular sectional form, it is formable through grinding finish by means of cylindrical grinding like a compression space, and high dimensional accuracy is securable so that a clearance between a swing cam 32 and the cam storage chamber 30 can be set to be very little. Moreover since this clearance between the cam 32 and the cam storage chamber 30 is interconnected to the side of a low pressure chamber of the compression space 9, lubricating oil 14 is sucked out of an oil filler port 38, and the clearance between the cam 32 and the storage chamber 30 is lubricated, and simultaneously penetration of high pressure gas in a space 16 of a hermetically sealed vessel into the compression space 9 comes to very little in quantity, thus extremely high volumetric efficiency is securable.

Title: Intermittent magnetic recording and reproducing device
Inventor: TOUGE KAZUTOMO
IPC: G11B5/027
Filed: 1991-08-28
Abstract: PURPOSE:To eliminate noise caused by changing heads by providing a switching signal generation part performing the changeover other than an effective vertical scanning period based on the output of a reference signal generation part. CONSTITUTION:A comparator 14 compares the amplitude of the reproduction output of each video head 1 to 4 which were inputted through amplifiers 5 to 8 and switches 10 and 11 at the intermittent reproduction. A switching signal generation part 17 is controlled to switch the amplitude to the larger one after the input of the comparison result, and holds the signal outputted other than the effective vertical period while receiving an H-SW signal from the reference signal generation part 13 and not receiving a signal from the comparator 14 during the effective vertical scanning period of the video signal. Therefore, the switch 12 is switched to the one whose amplitude is larger only other than the effective vertical period, driving into the switching noise of the video heads 1 to 4. Thus, a reproduction video with no head switching noise apparently can be obtained.
