Patent JP-H07249855-A (JP)
Title: Printed wiring board and its manufacture
Inventor: ADACHI TAKEMA
IPC: H05K1/09
Filed: 1994-03-09
Abstract: PURPOSE:To keep a printed wiring board high in performance and quality for a long time by a method wherein an upper metal layer close to an upper layer is set to have a larger ionization tendency than a lower metal layer close to a lower layer. CONSTITUTION:An upper layer 322 of metal (Ni or the like) out of two adjacent metal layers 321 and 322 and close to an upper layer 33' is set to have a larger ionization tendency than a lower layer 321 of metal (Pd or the like) close to a lower layer 31. Therefore, even if corrosion advances in the upper layer 322 of metal (Ni), the lower layer 321 of metal (Pd) hardly corrodes. By this setup, even if the upper layer 33 of expensive precious metal is set thin, it can be kept high in corrosion resistance, so that a printed wiring board of this constitution can be kept high in performance and quality for a long term.

Filed: 1992-02-05
Abstract: PURPOSE:To allow movement in a simple structure and even micro-movement by giving vibration to a frame in a specific mode with the vibration of a piezoelectric vibrator for movement along the grounding surface thereof in the use of horizontal propulsive force. CONSTITUTION:A piezoelectric vibrator 2 has the end face fixed at a preset position perpendicular to the grounding surface 4 of a frame 3 which is composed of a square closed loop. A frequency adjusting volume control 9 for a controller 8 is adjusted so that the drive frequency of the piezoelectric vibrator 2 may correspond to the reasonable frequency of the frame 3. In accordance with such adjustment, reasonable-frequency pulse drive waveforms are output from a comnander 11. After they are amplified by an amplifier 12, analogous voltage is applied to the piezoelectric vibrator 2 and then the vibration is transmitted to the frame 3. A micro-movement device 1 moves with the specific components of vibration serving as horizontal propulsion force. Its speed is set up by the adjustment of a voltage adjusting volume control 10.

Title: Thermal head
Inventor: NAKAYAMA SHOJI
IPC: B41J2/335
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of a print spot by making a trench at a part for forming a heating resistor of a heat dissipation plate being pressed against a head substrate on the side where the heating resistor is not formed thereby making uniform the heat distribution of a thermal head. SOLUTION: In a thermal head, contact state between a head substrate 2, a heat dissipation plate 1, and the like, are not uniform because of waving of the head substrate 2, fluctuation in the smoothness of the heat dissipation plate 1, and the like. A trench 11 is thereby made in the heat dissipation plate 1 at a position corresponding to a heating resistor 21 being formed on the head substrate 2 while covering the overall length thereof across the entire region in the longitudinal direction. Since a heat dissipation plate 10 does not directly touch the side of the head substrate 2 where the heating resistor is not formed, heat dissipation can be made uniform even when the head substrate is waving and occurrence of print spot due to difference of heat storage can be prevented.

Title: Method and equipment for formation of wiring insulation film of semiconductor device
Inventor: OTSUBO TORU
IPC: H01L21/3105
Filed: 1990-03-19
Abstract: PURPOSE:To enable high-yield manufacture of a device of highly integrated multilayered wiring structure by charging an etching gas containing fluorine atoms into a plasma CVD film-depositing gas to proceed film deposition from this gas by plasma while making reactive ion etching with the etching gas. CONSTITUTION:A plasma CVD film-depositing gas charged with an etching gas (reaction gas) containing fluorine atoms is fed into a treatment chamber to generate plasma 60, thereby depositing an insulating film on the wiring pattern of a treatment substrate 9 by plasma CVD from film-depositing gas upon heating. On the other hand, reactive etching is conducted by evaporation upon chemical reaction of fluorine gas ions of the reaction gas entering by potential difference developed between the plasma 60 and the lower electrode 3 with the result that a high-quality insulating film is formed on the wiring pattern of the treatment substrate 9 without voids. This process enables flat formation of a surface without being influenced by ruggedness of the insulating film surface generated by a wiring film and therefore high-yield manufacture of semiconductor devices.

IPC: F25D11/04
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To remove condensate, adhered to a heat exchanger caused by the opening and closing of a door for a freezing chamber, automatically by a method wherein the stopping or starting of the freezing operation of the freezing chamber is controlled by a coinciding signal, outputted when a time data has arrived at a predetermined set value. SOLUTION: A control unit 14 outputs a control signal to a set circuit 100 so as to use a heating time data TS'. At the same time, a counting circuit 10 starts counting after being cleared so as to show '0'. In this case, a comparing circuit 13 starts a comparing between the counting signal T and the heating time data TS'. Subsequently, the control unit 14 continues the process of defrosting of condensate, adhered to the heat exchanger, until the counting signal T and the heating time data TS' has coincided. Thereafter, when the counting signal T coincides with the heating time data TS' under a condition that (T=TS'), the comparing circuit 13 outputs the coinciding signal K into the control unit 14. The control unit 14 confirms that the defrosting work in the heat exchanger is finished by the inputting of the coinciding signal K and stops the defrosting process of the heat exchanger.
