Title: Manufacture of hybrid integrated circuit device
Inventor: ARIYOSHI SHOGO
IPC: H01L21/60
Filed: 1989-03-22
Abstract: PURPOSE:To manufacture a high density product in which spacings between bumps are so small with high reliability and at a low cost by a method wherein the apertures for the bump parts of a solder paste printing mask corresponding to a flip chip are so provided as to make the adjoining apertures shifted from the centers of the corresponding bumps alternately. CONSTITUTION:In order to manufacture a hybrid integrated circuit in which a flip chip IC is employed, solder paste 9 is applied by using a solder paste printing mask 20 in which oval or deformed oval apertures 21 corresponding to the flip chip are so provided as to make the adjoining apertures 21 shifted from the centers of the corresponding bumps alternately. For instance, the solder paste printing mask 20 is composed of a stainless steel sheet having a thickness of 100-200mum and the apertures 21 are provided in the mask 20 in such a manner that, when the solder paste 9 is applied by using the mask 20, the soldered parts 9 of the adjoining bumps are alternately shifted as shown in the figure. With this constitution, fusion of the adjoining bumps caused by the relaxation of the solder paste in a reflow process can be avoided.

Title: Card reader/writer
Inventor: OSAKI KEIYA
IPC: G11B17/00
Filed: 1995-03-29
Abstract: PURPOSE: To prevent writing and reading errors from occurring by providing a thermal sensor for detecting the temperature of a pressing plate and a sensor for detecting the position of an inserted card. CONSTITUTION: A card 2 inserted into a card reader/writer 1 is carried toward a magnetic head 12. When the tip of the card 2 reaches the position of a transmissive type sensor 8, a motor 11 is stopped by means of the detecting output of the sensor 8. Thus, the card 2 is stopped immediately below a pressing plate 3 as a warpage correcting mechanism part, electric conduction to a heat generating body 6 is simultaneously started and the temperature of the pressing plate 3 is increased. Then, when its arrival to a specified temperature is detected by a thermal sensor 7, a power is supplied to a solenoid 5, the solenoid 5 drives the pressing plate 3 downward against a spring 4 and applies pressure to the card 2. Thus, the warp of the card 2 is corrected.

Title: Electronic level
Inventor: KUMAGAI KAORU
IPC: G01C15/00
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To enable an electronic level to discriminate the pattern formed on the surface of a leveling rod for electronic level without hindrance even when a shadow is formed on the patterned surface of the rod by projecting pulsed measurement supporting light upon the rod. SOLUTION: A microcomputer 28 causes a semiconductor laser 31 to emit a laser beam through a driving section 17. The intensity of the laser beam emitted from the laser 31 is adjusted to such a degree that the beam is not affected by the shadows of trees. The reflected beam of the laser beam from a leveling rod 1 for electron level is made incident on a sensor through an objective lens 10 and a beam splitter 14 divides the reflected beam in two directions toward an eyepiece 7 and a CCD linear sensor 15. Since an electric shutter 30 is provided in front of the sensor 15, driven synchronously to the laser 31, and released only when the reflected beam from the rod 1 is made incident on a sensor, the incidence of external light is suppressed and, accordingly, the S/N radio of the level is improved.  In addition, since only a necessary part is irradiated with pulsed measurement supporting light, the power consumption of the electronic level is reduced and the level can make measurement with high accuracy.

Title: Substrate for loading microscopic sample and sample illumination method using the same
Inventor: KATO KENJI
IPC: G02B21/06
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily and efficiently execute photoirradiation by total reflection to a thin sample or microparticle sample, etc., with a good contrast by forming at least a part to be a slab optical waveguide layer. SOLUTION: A sample 5 is placed on the slab optical waveguide layer 3 of the substrate 1 for loading of the microscopic sample and light is introduced under a total reflection condition into the slab optical waveguid layer 3. The light is then totally reflected by the boundary between the slab optical waveguide layer 3 and air 4, by which evanescent light is generated onto the surface of the slab optical waveguide layer 3 and is oozed onto the slab optical waveguide layer 3. The oozing depth of the evanescent light is as extremely shallow as approximately equal to the wavelength of the light or a fraction thereof and, therefore, only the part placed extremely near the surface of the slab optical waveguide layer 3 is eventually selectively illuminated.  Then, the efficient execution of the photoirradiation to the thin sample, microparticle sample, etc., by total reflection is made possible even in the case the installation space is extremely narrow.

Abstract: PURPOSE:To compose all circuits by electric system by a method wherein the peak frequency of the gain distribution of an optical amplifier is controlled by the induced electric signal generated by an interacrion between input signal and carrier in the potical amplifier. CONSTITUTION:DC bias current from a DC source 3 and low frequency sine- wave signal omegam from an oscillator 5 are superposed and supplied to a semiconductor laser optical amplifier 2. Then inducted electric signal generated in the semiconductor laser optical amplifier 2 by an interaction between FM input signal light 1 and the low frequency sine-wave signal omegam is applied to a band- pass filter 11 and a 2omegam component is taken out. Then a processing circuit 12 judges wether the input signal carrier frequency is on the low frequency side or the high frequency side of the gain distribution taking the signal of the oscillator 5 as a standard. A DC source is controlled by this judgement and the maximum value of the gain of the semiconductor laser optical amplifier 2 is tuned to the carrier frequency of the FM input signal light 1.

Title: Image density adjusting device
Inventor: SUGINO OSAMU
IPC: G03G15/00
Filed: 1987-03-26
Abstract: PURPOSE:To obtain an image of a stable and adequate density without being affected by a change in the sensitivity characteristic of a photosensitive body by controlling image forming conditions according to the detected values of the surface potential in the region on a recording body where the image corresponding to a reference member is formed and the surface potential in the region on the recording body where the image corresponding to an original is formed. CONSTITUTION:This device has a sensor to detect the surface potential of the photosensitive body. The output for adjusting the image density is controlled according to the detected output values of the original and the reference member plate by using said sensor. More specifically, the potential of a reference white plate is first measured at the time of preliminary scanning, then the average potential of the original is measured. The control of the adjusting device is then executed by using the potential of the original and the potential of the white plate as the output of this original. The stable adjustment of the image density is thereby permitted without being affected by a change in the photosensitivity characteristic by the use of the photosensitive body.

IPC: G02B7/02
Filed: 1990-03-20
Abstract: PURPOSE:To obviate the generation of the stress to be the cause for a wave front aberration by adhering the surface on the incident side or exit side of an optical lens via an adhesive provided in the groove formed in the position on the circular hole side of a collar part. CONSTITUTION:The annular groove 12 is formed in the inward collar part 11 provided in the circular hole 10 of the holder (h). While the flange part of the lens L is imposed on the inward collar part 11 of the holder (h) and the low melting glass 9 in the annular groove 12, the entire part is put into a furnace and is heated to melt the low melting glass 9 and is then slowly cooled, by which the lens L is fixed to the holder (h). The deformation in an arrow direction is generated by a difference in coefft. of thermal expansion between the adhesive 9, the lens L and the holder (h) during the cooling, but only the surface on the incident side or exit side of the lens L is in contact with the adhesive 9 and, therefore, the other parts can be freely deformed on the basis of the contact point with the adhesive 9. The stress is hardly accumulated in this way and the aberration is suppressed.
