Patent JP-H03266473-A (JP)
Title: Manufacture of semiconductor pressure sensor
Inventor: KAMIJIYOU TAKETOMO
IPC: G01L9/04
Filed: 1990-03-16
Abstract: PURPOSE:To prevent a deep recess from being induced in a semiconductor wafer by a method wherein openings provided to a dry etching mask located at the peripheral part of a wafer are formed larger than those located at the other part when recesses are formed at corresponding positions on a diaphragm where a gauge resistor is provided. CONSTITUTION:An Al evaporated film 4 is provided onto the N<+> layer of a silicon wafer, and a resist film 5 provided with small openings 8 at its center and large openings 81 at its periphery is formed thereon. When a dry etching processing is carried out using this Al mask, recesses 71 formed through the openings 81 provided at the peripheral part of the mask are shallower than recesses 7 located at the center due to a low etching rate. Therefore, a recess so deep as to penetrate through a wafer is hardly formed. On the contrary, as the recesses 7 located at the center are uniform in depth, they are formed uniform in depth so as to have a prescribed depth by stopping an electrolytic plating process at an interface between an N<+> layer 1 and a P layer 2. By this setup, a recess located at the peripheral part if a semiconductor wafer is prevented from being formed so deep as to penetrate through the wafer, and recesses nonuniform in depth can be prevented from being formed.

Inventor: IBATA AKIHIKO
IPC: B21K23/00
Filed: 1982-04-19
Abstract: PURPOSE:To obtain a magnet having high magnetic characteristics in the diametric direction with small compressive stress by a method wherein a hollow steel piece of magnet of polycrystalline Mn-Al-C system that has been made anisotropic is compressed in the axial direction at the preselected temperature in such a state that its external periphery is restricted, whereas at least part of the internal periphery is set free. CONSTITUTION:A known alloy of Mn-Al-C system for preparing a magnet is extrusion- processed at the temperature range of 530-830 deg.C and subjected to plastic working so as to prepare a uniaxial or facial anisotropic magnet which can be easily magnetized in the direction of extrusion. The external periphery of a hollow steel body 1 of the alloy magnet is restricted, while part of the internal periphery is set free, before being compression-processed in the axial direction. Then a magnet having high magnetic characteristics in the diametric direction can be obtained in either case. In the case of the magnet having the steel body easily magnetized in the axial direction, the compressive stress is 0.05 or more expressed in terms of a logarithmic value. If part of the steel body processed by compression is further compression-processed in the axial direction, the processed part of the magnet shows higher magnetic characteristics in the diametric direction.

Title: Mist heat exchanger
Inventor: KUWABARA HEIKICHI
IPC: F28F1/32
Filed: 1979-05-30
Abstract: PURPOSE: To improve heat-conducting performance, by separating grooves, which extend crossing the longitudinal direction from a pointed fin, which is provided between the grooves, and by providing a notch on the surface of a pipe being directly contacted by gas flow.  
     CONSTITUTION: Mist contained in a gas flow A adheres to an area 4a on the top of front side of a fin 2 and also to an area 4b on the bottom of front side of the fin 2, and a groove 4 is immersed in liquefied mist. The liquefied mist in the bottom 4b on front side of the groove 4 flows down to the lowermost thereof by the gravity and the movement of the gas flow A, while a part of the mist flows to the bottom 4C on the reverse side, and excess mist falls down. The liquefied mist in the area 4a flows to 4d being pushed upwardly by the movement of the gas flow A. In this case, the mist in the range 4a does not flow downwardly because it is separated by the notch 5. As the reverse side of the heat-conducting pipe is thus wetted by the liquefied mist, heat-conducting performance can be improved.

Filed: 1992-03-25
Abstract: PURPOSE:To shorten the processing time without performing extra re-editing operation by roughly determining the position of a floating area first, and determining the whole appearance and then converting the floating area into a fixed area by an area conversion part. CONSTITUTION:When a key for fixing the floating area is inputted from an input part 2 at the time of document preparation, a control part 1 informs an editing part 5 of the fixation of the specified floating area and the area conversion part 10 converts the floating area into the fixed area. The area conversion part 10 takes information regarding the floating area specified by the control part 1 out of the data storage part of a floating processing part 8, copies it to the data storage part of a fixing processing part 9, and deletes the information in the data storage part of the floating processing part 8. Then, body data before the converted fixed area are proofread and even if the number of lines is changed, neither the movement of the position nor re-editing is performed since the area is the fixed area. The editing in the area is performed by the fixing processing part 9.

Title: Fourier transform spectroscopy using pulse light source
Inventor: MASUTANI KOJI
IPC: G01J3/45
Filed: 1991-03-29
Abstract: PURPOSE:To facilitate measurement using a pulse light source of a longer emission period, by a method whereby frequency components in a specific range of output signals of a detector are taken out, sampled and Fourier-transformed, and the spectrum of a measuring light is obtained. CONSTITUTION:An FT-IR/spectrometer part is comprised of a synchronous pulse light source 1, an interferometer 2, a sample 3, a detector 4 and a preamplifier 5. An output of the detector 4 is, through a band pass filter 6, input to a main amplifier 7 of an FT-IR/signal processing part and sampled for Fourier- transform. Supposing that the minimum of the frequency (f) of the spectrum of the measuring light modulated by the interferometer 2 is fmin, and the maximum of the frequency is fmax, the light source 1 repeatedly emits light with a period tau satisfying (m+1)/2fmax>tau>m/2fmin wherein (m) is a positive integer. In other words, when the spectrum of the measuring light is present only in the range (m+1)/2tau>f>m/2tau, this method is applicable. Accordingly, the spectroscopy can be performed with using a pulse light source of a longer emission period.

Title: Manufacture of multilayer circuit board
Inventor: KYOI MASAYUKI
IPC: H05K3/46
Filed: 1993-03-25
Abstract: PURPOSE:To suppress warpage generated at a board at the time of forming an insulating film layer without improving a linear expansion coefficient of an insulating material by cooling a material having smaller linear expansion coefficient than that of an insulating layer material at least during cooling while pressing the material by a jig in the step of forming the layer. CONSTITUTION:A jig plate 23 is heated and pressurized and held for a predetermined time in order to cure uncured resin 2 to become an insulating film layer. Then, in order to increase a frictional force between an upper jig 24 and the layer to enhance a lateral compression force of the layer when cooling is started, a temperature is lowered while applied pressure from upper and lower surfaces of the plate 23 is being applied. Since the lateral compression force by the frictional force to the plate 24 is applied to the layer during the cooling, tensile stress finally remaining at the layer is alleviated, and warpage is also reduced. Further, since a conventional material is used to suppress warpage of a board, it is not necessary to evaluate the reliability of a novel material, and hence a low cost effect is provided.
