Title: Pattern forming method
Inventor: CHOKAI MINORU
IPC: G03F7/039
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To recover a degraded beam shape and to form a good fine pattern by forming a thin film comprising a photosensitive compsn. having inhomogeneous density distribution in the thickness direction and using a photoresist which causes photofading in the wavelengths of exposure light. SOLUTION: A photofading layer which converts a degraded beam shape of exposure light with low contrast into a good shape with high contrast is formed on a chemically amplifying photoresist. As for the photofading layer, various photofading dyes having absorption of light in the wavelengths of exposure light can be used. It is especially preferable to use a photosensitive agent as the dye used for the photofading layer, because not only the beam shape of the exposure light but development characteristics are improved.  Even when the upper photofading layer is mixed into the photoresist layer, it is no problem as far as the density distribution of the photofading layer gives the highest density on the surface of the photofading layer while the density gradually decreases in the depth direction of the photoresist and becomes lowest near the substrate in the lower part of the photoresist layer. A continuous decrease in the density distribution is more preferable because reflection on interfaces in a multilayered structure is prevented.

Title: Liquid chromatograph mass spectrometer
Inventor: YAMAUCHI ETSUO
IPC: G01N30/84
Filed: 1983-06-17
Abstract: PURPOSE:To make it possible to accurately analyze even a liquid sample containing volatility retardant components by mixing the developer from a liquid chromatograph with a matrix such as to gain a predetermined fluidity and continuously supplying the mixture onto a target inside the ionization chamber of a mass spectrometer. CONSTITUTION:At a mixing part 11, a developer from a liquid chromatograph 12 is mixed with a matrix (glycerol or the like) transmitted from a matrix supplying source 14 through a pipe 13. Thereupon, the mixture is arranged to flow at a proper flow rate from a pipe 8 onto a target 4 having a V-shaped groove 7 and is then received by a waste liquid device 9. The sample in the groove 7 of the target 4 is irradiated with a neutral corpuscular radiation 6 emitted from a high speed neutral corpuscular radiation generator 5, and the resultant ions are accelerated and converged by means of a group of electrodes. Thereafter, detection is effected at an analyzing part 1 of a mass spectrometer. It is thus practicable to qualitatively and quantitatively analyze even the sample mixed with the volatility retardant components, and the sample liquid is directly ionized, which process eliminates the need for its evaporization and thickening of the solvent. Moreover, highly accurate analyses are made practicable.

Title: Band compression television signal converter
Inventor: YAMADA AKIHIKO
IPC: H04N7/01
Filed: 1990-04-26
Abstract: PURPOSE:To prevent resolution of a still picture from being deteriorated by mixing signals from each of in-field and inter-frame insertion circuits at a mixture circuit with weighting and decreasing the scanning line number to line density of an NTSC signal system at a scanning conversion circuit of a post-stage. CONSTITUTION:A time axis conversion circuit 31 expands a clock rate of a digital MUSE signal into a clock rate of an NTSC signal. While an inter-frame insertion circuit 33 applies inter-frame interpolation processing, an in-field interpolation circuit 35 applies in-field interpolation processing. Moreover, a mixture circuit 41 uses a moving detection signal from a moving detection circuit 37 to weight a signal from the inter-frame interpolation circuit 33 and miles the result and it is outputted to a scanning conversion circuit 43 and a scanning conversion time expansion circuit 15. Then the scanning line of the MUSE signal system is converted into the scanning line of the NTSC system. Thus, the resolution of the still picture is improved and the processing is simplified.

Title: Schottky barrier diode
Inventor: URANO HIROSHI
IPC: H01L29/872
Filed: 1978-09-07
Abstract: PURPOSE: To protect an exfoliation of a barrier metal from a protective layer owing to heat cycle by forming a circumference of the barrier metal to contact with the opposite surface of the protective layer.  
     CONSTITUTION: On a high density layer N + 1, low density epi-layer 2 is deposited and protective layer 41 is formed on the layer 2 and then ring-shaped window having a determined circumference width is opened and a guard ring 3 is formed on the opened portion of the window. Then, after protective layer 4 is formed on whole surface, window is opened in such manner that the protective layer 4 rest on outer circumference of upper surface of the guard ring 3. Then barrier metal 5 is formed on the opened portion of the window in such manner that it contacts with opposite surface of the protective layer 4 without overlapping each other. Then on the barrier metal 5, ohmic metal 6 is vapor-deposited and electrodes 7 are deposited on upper surface of the metal 6 and lower surface of the layer 1. Thus, the circumfernce of the barrier metal 5 does not cover over the protective layer 4 and so the barrier metal 5 cannot be exfoliated from the protective layer 4 owing to heat cycle. Accordingly, the lowering of the element charactristics owing to an exfoliation of the barrier metal does not occur.

The temperature of the pipe blank 22 rolled by the elongator 3 is measured by the thermometer 4, and its length is measured by the length meter 5. The forecast rolling load for each pass is obtained from the rolling load forecast model made in consideration of above measured values of the temperature and length, and the roll gap for the first pass is corrected by the learning control depending on the actual rolling performance in the former pass by the same plug and on the aim size. Besides, the increment of the wall thickness at the groove bottom is obtained from the actually measured rolling load in the first pass and the forecast rolling load; and the increment of the forecast rolling load for the second pass is obtained from the actually measured pipe blank's temperature in the first pass and the forecast rolling temperature; hereby, the roll gap for the second pass is corrected.

Abstract: PROBLEM TO BE SOLVED: To allow a low-torque motor to be adopted as a loading motor by temporarily applying a voltage higher than a normal voltage to the loading motor only during a certain period of time immediately after the start of unloading and thereafter applying the normal voltage until the completion of the unloading. SOLUTION: When an unloading completion detecting switch 26 and a loading completion detecting switch 27 that are tray sensors S1 and S2, respectively, are both in the ON state, a command signal for driving a loading motor 83 to rotate in a reverse direction with a large voltage is output from a CPU 122 to an M-con 123, so that the loading motor 83 is driven to rotate in the reverse direction with a large voltage of 4.5 V which is obtained by adding 2.5 V to a normal voltage of 2.0 V. When the loading completion detecting switch 27 is switched from the ON state to the OFF state, a signal for switching the voltage to be applied to the loading motor 83 from the large voltage to the normal voltage is output, so that the applied voltage is changed to the 2.0 V and the reverse rotations continue while.

Title: Controller for electromagnetic clutch of vehicle
Inventor: TAKANO TOSHIO
IPC: B60W10/10
Filed: 1980-08-09
Abstract: PURPOSE: To avoid a gear noise at the time of gear shifting, by causing an inversely exciting current to flow through the coil of a clutch to remove the torque of the clutch itself due to residual magnetism when the speed of a vehicle is not higher than a set level and its transmission is in neutral position.  
     CONSTITUTION: When the speed of a vehicle is not higher than a set level and either gears are in neutral position or gear shifting is effected, a vehicle speed switch 51 is turned off to apply a signal of high level to a NAND gate 54. The gate 54 sends out a signal of high or low level depending on the on or off of a neutral switch 50. A shift lever 52 is turned on to transmit a signal of low level to a NAND gate 55. Under one of the conditions, the NAND gate 55 sends out a signal of high level to turn off transistors 40, 41 so that an electrical current flows through as a→c→b→e, namely, an inversely exciting current flows through a coil 7. For that reason, a driven member is not dragged by a driving member and synchronization is accelerated to smoothly engage the gears with each other.
