Title: Cleaning device for inert gas and gas chamber
Inventor: ARAKI KATSUTERU
IPC: B23K9/16
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To improve the purity of an inert gas for the welding of titanium, titanium alloy, stainless steel, etc., in the inert gas. SOLUTION: Helium gas introduced through an inlet port 26 into a space 8 is passed through a hole 5 into a reaction tube 7 containing granular titanium 11 heated and activated with a heater 9. The impurities such as oxygen, nitrogen and hydrogen in the helium gas passing through the gap between the titanium granules 11 are removed by reacting with titanium 11. The purified helium gas is dedusted with a dust-removing filter 13, cooled with a water-cooler 23 and discharged through an outlet port 16. An inert gas having high purity can be produced with a simple apparatus.

Title: Resist applying method
Inventor: IKEDA RIKIO
IPC: H01L21/027
Filed: 1990-03-19
Abstract: PURPOSE:To enable improving the in-plane uniformity of a resist film thickness by forming an application system, where no temperature difference exists, through setting of both resist solution and application atmosphere to the same temperature within the range of 24-30 deg.C and through application of the resist solution. CONSTITUTION:Both resist solution and application atmosphere are set to a same temperature within the range of 24-30 deg.C and the resist solution is applied subsequently. When a preset temperature exceeds 30 deg.C, not only a resist film thickness grows larger than required as the evaporation of a solvent is further activated but also the projection of the central part becomes too large. As a result, there is a possibility that an in-plane uniformity is impaired. Moreover, a surplus energy is required for heating. Therefore, a temperature higher than a preset one has little practical merit. Thus, it is possible to obtain an excellent in-plane uniformity, also when the resist solution and application atmosphere is set to the same temperature. In this manner, a resist application excellent in controllability and reproducibility can be performed with not improvement of the existing resist applicators.

Title: Magnetic disk device
Inventor: TSUNODA MASATOSHI
IPC: G11B5/09
Filed: 1980-05-21
Abstract: PURPOSE:To prevent an operation of a read-only switch from giving an evil effect to the recording action, by adding a flip-flop circuit to which both a unit selection signal and a read-only signal are applied via a logical gate circuit. CONSTITUTION:A logical gate 32 supplies the output of a reverse gate 30 which turns a unit selection signal 7 into a reverse logical output 31 and a read-only signal 11 respectively. An OR gate 33 uses an output 34 for its input, and a flip-flop 35 uses the output of the gate 33 for its input. Furthermore a logical gate 37 uses the signal 7 as well as a gate read-only signal 36 connected to a blocking input terminal of a record current supply circuit 5 as well as to a line driver 18 with the output of the flip-flop 35 for its input. Then a clock signal 39 is applied to the flip-flop 35. As a result, the output 36 of the flip-flop can be prevented from varying by an operation of a read-only switch 12 when the signal 7 is set at a high level.

Title: Tape cartridge
Inventor: MIZUTANI HIKARI
IPC: G11B23/087
Filed: 1994-03-11
Abstract: PURPOSE:To improve the ease of the assembly of a leaf spring which is pushed in the state of elastic deformation of an approximate V-shape into a gap between a locking tool which holds a front cover in a closing posture and a spring receiving wall. CONSTITUTION:A leaf spring 12 has a central folded part 12a and a pair of arm parts 12b and notches 12e are provided in the junction parts between the central folded part 12a and the arm parts 12b symmetrically in the leaf width direction. The stress is concentrated to the notch 12e and hence the bending rigidity of the arm part 12a is declined, so that a locking tool 11 is prevented from being pushed out from a side wall 9. When the leaf spring 12 is inserted into a gap between the locking tool 11 and a spring receiving 20 from its top end, an angular moment does not act on the leaf spring 12 itself, so that the leaf spring 12 can be inserted smoothly and securely.

Title: Electric power synthesizer
Inventor: KOIDE HIDEYUKI
IPC: H01P5/12
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To facilitate assembly and to improve the same phase, the same amplitude property and the isolation characteristics of signals by setting a conversion part for converting the incident wave of a microwave or a milliwave from a coaxial mode to a radial mode to be a single structure and providing slits for a disk-like conductor constituting a radial waveguide. SOLUTION: The conversion board 6a and the holding part 6b of a second conversion part 6 are set to be the single integral structure. Thus, the phases and the amplitude of the signals which are inputted from respective side terminals 4 and which are transmitted through the radial waveguides 7 are made equal by making the terminals so that they can easily and coaxially be fitted to a first disk-like conductor 1. Then, the loss is reduced and the impedance of the fitting position of the conversion part 6 is set to be equal and the high isolation characteristic can be obtained. Furthermore, the plural radiation-like slits 9 whose depth in a normal direction is about 1/2 of a transmission signal wavelength are provided for the disk-like conductor 1.  Then, radiation to an outer part is prevented and the transmission loss can be reduced by inserting resistors 10 into the maximum points of the electric field, which are induced in the slits 9.
