Title: Method for processing silicon wafer
Inventor: ORIMO YASUSHI
IPC: B81C1/00
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To enable improvements in alignment accuracy between a circuit element and a recess formed on both sides of a silicon wafer by opening a throughhole in the silicon wafer by anisotropic etching and using this through- hole as a reference. SOLUTION: In a through-hole forming process, each through-hole 22 is formed on a back side 21B of a silicon wafer 21 by anisotropic etching. In an element-forming process, each piezoresistive element 25 is formed on a surface side 21A of the silicon wafer 21 with reference to each alignment mark 38 based on each through-hole 22. In a recess-forming process, a recess 26 is formed on the back side 21B of the silicon wafer 21 by anisotropic etching with reference to each through-hole 22. Thus, even in the case where there is a processing error on the surface 21A to be a cut surface of the silicon wafer 21, each piezoresistive element 25 and the recess 26 can be easily aligned with each other on the both sides of the silicon wafer 21.

Title: Humidity exchange type air drying apparatus
Inventor: USUI AKIRA
IPC: B01D53/26
Filed: 1978-11-29
Abstract: PURPOSE: To protect an installation such as a building, a pipe arrangement or the like from the adverse effect by a mechanism wherein the drain containing nitrous acid or nitric acid generated by the reaction of NO x  formed in an ozone generator and the moisture within a humidity exchanger is diluted by water and discharged.  
     CONSTITUTION: The air of a room temperature and an atomospheric pressure is supplied under pressure by blower 1 and cooled to about 5°C in a cooler 2. The moisture of the cooled air is adsorbed in one side of a humidity exchanger 4a to form the highly dried air of a dew point-below 50°C, thereafter flowed into an ozone generator 7 and a part of O 2  in the air is converted O 3  to form the ozonized air. This ozonized air is flowed into the other side of a humidity exchanger 46 and supplied into an ozone oxidizing apparatus through a three-way valve while the moisture within a humidity absorbent is removed. When the humidity exchanger completes the humidity absorption and switched to the start of the humidity removing operation, a valve 9a, 9b are opened for few seconds to supply a nitric acid solution to a diluting water tank 11 and diluted until pH6 by supplying a predetermined cooling water to the tank 11 from the ozone generator 7.

Title: Carriage mechanism for floppy disk device
Inventor: HANDA MAKOTO
IPC: G11B21/02
Filed: 1986-06-24
Abstract: PURPOSE:To always stably move a carriage by providing a plate spring member in contact with a lead screw so as to be retained by a needle member and fitted to a carriage so as to give the pressing force to the carriage in a prescribed direction. CONSTITUTION:In driving stepping motor 11, the lead screw 10 is diriven. Since a needle 13 is in contact with the slot of the lead screw 10, the turning movement of a lead screw 10 is converted into a straight-forward motion and transmitted to the carriage 12. In such a case, since the plate spring 20 acts on the lead screw 10 to be pressed toward the needle 13, the needle 13 is moved along the slot of the lead screw 10 surely without being removed out of the slot of the lead screw 10. Since the plate spring 20 is fitted obliquely with respect to the horizontal direction of the needle 13, the plate spring 20 depresses the lead screw 10 toward the needle 13 and depresses the carriage 12 in a direction opposite to the lead screw 10.

Title: Thermal printer
Inventor: NAKAMURA MASAHIRO
IPC: B41J2/32
Filed: 1981-09-19
Abstract: PURPOSE:To obtain a printer possible to speed up recording by simultaneously performing preheating and recording with a transfer head which adjacently integrates a magnetic plate having a good electric conductor thereunder and a platen which is composed of a magnetic body to which an alternating magnetic field is applied. CONSTITUTION:A thermal printer is composed of a transfer head 3 adjacently integrated with a magnetic plate 2 equipping a good electric conductor 1 thereunder, and a platen 7 consisting of a C-shaped magnetic body 4 which is facing to the under surface of the transfer head and coiled by wire 5 and a plane plate 6 which is composing of non-magnetic/non-conductive materials on the magnetic pole thereof. Applying an alternating magnetic field on the magnetic body 4 by means of the coiled wire 5, a magnetic field loop is generated between the magnetic body 4 and magnetic plate 2. Thus a magnetic flux flows through the good electric conductor 1, and the heat generated thereby heats up a transfer layer 8 through a transfer media 10. At this time, as the strength of the magnetic field applied onto the magnetic body 4 is selected, and the transfer layer 8 has been already preheated, the transfer can be accomplished by a low level input.

Title: Electromagnetic flowmeter
Inventor: KAWAMATA ISAMU
IPC: G01F1/58
Filed: 1982-08-25
Abstract: PURPOSE:To obtain the titled flowmeter, which is characterized by a high utilization rate of a material and a steady loss and does not generate noise voltage when the meter is disassembled and reassembled after the fabrication, by forming an iron core by casting and the like as a unitary body, and adding silicon to the iron core. CONSTITUTION:The iron core, to which magnetic flux is returned, is formed so that its magnetic resistance is symmetrical with respect to a line (a)-(a') on its right and left sides. Pole faces 10 and 10', which face each other in parallel, are finished by machining since a magnetic field is applied in the vertical direction to a pipe. Thus the irregularities on the surfaces are eliminated and the length of the magnetic path is made minimum. The core is divided into at least two parts, upper and lower. Under the state the upper part, to which signal leads are connected, is fixed, the lower part of the iron core and winding as a unitary body can be removed by loosening a screw 8. In this constitution, the uniform magnetic field can be readily obtained, and the dispersion of the magnetic field is very small. Since the meter can be constituted by one sheet of case iron core, cast steel, or pure iron, the loss is equalized and the control of material quality is facilitated.

Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To reduce solder bridges by a method wherein the connecting terminals formed of through holes are solder connected to the connecting terminals formed on a flexible substrate by a thernmal pressure fixing process so as to absorb surplus solder into the through holes. SOLUTION: Through holes 3 are formed in respective connecting terminals 2 of thermal pressure fixing substrate 1. Next, the inner walls of the through holes 3 are plated. Furthermore, a flexible printed substrate 5 and the thermal pressure fixing circuit substrate 1 with respective connecting teminals 2 previously soldered are overlapped with each other so that respective connecting terminals 2 and 6 may be opposed. Next, both substrates 1, 5 are soldered for connection by pressurizing and heating downward from the flexible printed substrate 5. Through these procedures, the occurrence of solder bridges can be reduced, since surplus solder can be absorbed into the through 3 in said connecting terminals 2.
