Title: Process for etching lowly reactive material in the presence of higher reactive material
Inventor: RANGARAJIYAN JIYAGANNAATAN
IPC: H01L21/3213
Filed: 1992-09-02
Abstract: PURPOSE: To selectively etch a low reactive material by arranging the low reactive material, high reactive material and complexing agent in a chemical environment contg. a nonaqueous medium and releasing ions from the low reactivity material, thereby forming a complex.  
     CONSTITUTION: The patterns of high reactive cobalt are formed on a low reactive copper layer. The structural body is immersed into the nonaqueous soln. contg. the copper salt, such as cupric tetrafluoroborate, solvent, such as alcohol, and the complexing agent, such as alkene or alkyne. The cupric ions in the copper salt described above are oxidized by the electrons from the copper layer to form cuprous ions. The cuprous ions are released from the copper layer simultaneously therewith. These cuprouos ions are consumed by forming the complex body with the complexing agent described above and do not react with the cobalt. At a result, only the exposed copper layer is etched. The copper pattern layers having the cobalt pattern layers on the upper layer are thus formed without using a resist layer.

Title: Latch comparator
Inventor: ISHIHARA NOBORU
IPC: H03K3/0233
Filed: 1987-09-21
Abstract: PURPOSE:To reduce the hysteresis by providing a positive feedback circuit between clock terminals of noninverting and inverting phases. CONSTITUTION:The positive feedback circuit consists of transistors(TRs) Q9, Q11, a diode D, a constant current source 22 and a resistor RF. A signal at a drain of the TR Q9 is given to a gate of a TR Q6 to apply positive feedback and a current switching characteristic of clock differential pairs composed of TRs Q5, Q6 is improved. That is, in applying a voltage change of  V5 to VCLK of the clock signal terminal 3, the change  VCLK in the gate voltage of the TRs Q5, Q6 is expressed as  VCLK= V5+ I9.RF, where I9 is the current change in the TR Q9 and no loss exists in the TR Q11 and the diode D. Thus, the change is increased by the  I9.RF and the hysteresis is reduced considerably so as to attain steep changeover.

Title: Reflection type projection screen
Inventor: HIRATA REIJI
IPC: G03B21/60
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a reflection type projection screen projectable in broad daylight with large effective luminance and excellent visibility by making the density of hair lines, formed on the screen face, higher at both side parts than the center part of the screen. SOLUTION: In a reflection type projection screen 2, the density of hair lines 2a at the center part of the screen is relatively the lowest, and the density of hair lines 2a' are gradually higher toward the right end and left end from the center part. Hair lines 2a are thus formed on the metallic surface to be a screen face, so that light is efficiently reflected or diffused by the hair lines 2a. Since the hair line density on both sides of the screen is higher than the hair line density at the center part, light is diffused relatively efficiently on both sides compared with the screen center part, and the lowering of luminance on both sides of the screen is reduced.

Title: Method for controlling path changeover transmitter and the path changeover transmitter
Inventor: ASHI MASAHIRO
IPC: H04J3/00
Filed: 1994-09-29
Abstract: PURPOSE: To eliminate the need of a changeover information transmission signal line and to provide a path changeover function with simple constitution by selecting one of the paths of plural systems based on information displayed in a path state identifier and predetermined logic. CONSTITUTION: When a fault is generated in an active VT1.5 signal path, a fault detection circuit 42 provided in a reception interface part 1 detects it. The fault state of the VT1.5 signal path is displayed in the path state identifier of the overhead area of the signal as fault generation. When the VT1.5 signal of the active path for which the fault generation is displayed in the path state identifier arrives at a path selection part 6-1, a path state identifier detection circuit 44-1 informs a control circuit 46 of a fact that the state identifier of the active path is changed to the fault generation. Then, in the case of being informed of the fault generation, the circuit 46 recognizes that the fault is generated in the active VT1.5 signal path selected at present and selects a reserve VT1.5 path.  That is, a selector 45 selects an input port corresponding to a value read from a system selection information holding memory 47.

IPC: G01N21/87
Filed: 1983-12-13
Abstract: PURPOSE:To detect the three-dimensional presence position of the stria of a rough quartz, by observing the transmitted light image of the rough quartz by a TV receiver while a spot like light source is revolved continuously. CONSTITUTION:A rough quartz 25 being an object to be inspected and a matching solution 26 are received in a glass container 27 while a continuously revolving spot like light source 28 is arranged above the container 27. Light emitted from the revolving light source 28 is allowed to irradiate the rough quartz 25 through the matching solution 26. Subsequently, the transmitted light image of the rough quartz 25 is picked up by an image pick-up tube 23 and projected on a TV receiver 29. Therefore, by observing the receiver 29, the planar presence position of the stria present in the rough quartz can be observed along with the presence position in a thickness direction. By this method, the three-dimensional presence position of stria of the rough quartz can be detected.

IPC: H01F41/06
Filed: 1991-08-21
Abstract: PURPOSE:To enable winding of a linear member on a plurality of winding objects simultaneously by relatively revolving a first attaching part and/or a second attaching part to the other. CONSTITUTION:A winding nozzle 5 is formed hollow and an electric wire 6 which is one example of a linear member which is wound on a drum is inserted through it. Bobbins 7 of the same number as the winding nozzles 5 are provided in an arrangement corresponding to the winding nozzle 5 not to rotate on a second attaching part 8. Since an end of the electrical wire 6 is fixed to an outer periphery of the bobbin in advance, the electrical wire 6 is wound on an outer periphery of the bobbin 7. The electric wire 6 is led out from the drum in accordance with revolution of the winding nozzle 5, thereby further proceeding winding on the bobbin. When revolves, a first attaching part 4 repeatedly approaches and leaves the second attaching part 8 as shown by an arrow 11 by vertical motion mechanism; therefore, the electrical wire 6 is wound uniformly in a vertical direction of an outer periphery of the bobbin 7.

Title: Motor
Inventor: FUJITA NOBORU
IPC: H02K21/24
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To reduce the wasteful power consumption of a motor and, at the same time, to reduce the thickness of the motor as a whole. SOLUTION: In a motor 20, one bearing 26a is positioned on the inside of a rotational force transmitting section 30 and, at the same time, the other bearing 26b is positioned on the inside of a rotor 22. The transmitting section 30 around which a belt 32 is put is integrally constituted with a supporting body 27. Since the bearings 26a and 26b are provided at both ends of a shaft 21, the thickness of the motor 20 can be reduced by using thin bearings (having short press-fitting sections) as the bearings 26a and 26b and, at the same time, the useless power consumption of the motor 20 can be reduced by reducing the loads applied to the bearings 26a and 26b. Since a supporting plate section 41 functions as a plate spring supported at one end, the rotational deflection of the shaft 21 can be suppressed by pushing the end face of the shaft 21 downward.  Since the transmitting section 30 and the supporting plate section 41 are integrally molded, the number of parts can be reduced and the assembling work of the motor 20 can be simplified.
