Title: Method for mounting semiconductor parts
Inventor: KADOI KAZUHISA
IPC: H01L21/60
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To mitigate variation of bonding pressure of a bump toward a pad on a substrate, and to prevent electric resistance from increasing in a condition where the volume of a filled-in bonding agent is varied, by pressing the bump with a pressure onto the substrate pad before the bonding agent is cured, and removing the pressure after the bonding agent is cured. SOLUTION: A bonding agent 39 is applied to an upper surface of a substrate 33 making use of a printing technique. A head 30 is heated by a heating element 301 in advance, up to a temperature sufficient for curing the bonding agent 39. Further, a bonding pressure of a bump 36 toward a pad 34 on the substrate 33 is set. Since the head 30 is suspended until the bonding agent 39 is completely cured, the bump 36 remains maintaining the bonding pressure toward the pad 34. After completing curing of the bonding agent 39 by heating, the pressure at a suction port 302 of the head 30 for pressurization and heating is changed into an atmospheric pressure so as to release a chip from being supported by vacuum suction, followed by elevation of the head 30. Thus, the bonding agent 39 is also released from being heated.

IPC: H01L27/095
Filed: 1987-11-17
Abstract: PURPOSE:To make characteristics of FET elements uniform in a device wherein a plurality of FET elements are formed on the same substrate, by making the arrangement directions of drains and sources of all the FET elements constant. CONSTITUTION:In the respective FET elements 2, 3, the respective drain diffusion layers 41, 42, and the respective source diffusion layers 51, 52 are formed, and drain electrodes D1, D2 and source electrodes S1, S2 are formed. In this manner, the same layers 41, 42, and layers 51, 52 in a pair of FET's 2, 3 are arranged in the same direction. As a result, at the time of ion implantation, the inner forms of layers 41, 42 and of layers 51, 52 becomes almost identical independently of implantation direction. Even if alignment shift of gate electrodes G1, G2 occurs, characteristics of the elements 2, 3 become identical. Therefore characteristics of all elements are made uniform.

Abstract: PURPOSE:To attain the recording with high density and large capacity by turning a plane mirror around the center of laser light incident in the plane mirror so as to apply high speed scanning with a minute beam spot. CONSTITUTION:The laser beam from a light source 101 becomes a circularly polarized light via a polarized beam splitter 103 and a 1/4 wavelength plate 104, reflected in a mirror 106 turned with a tilt of 45 deg. with respect to the optical axis 111, converged into a beam spot 100 of nearly 1mu diameter by a converging lens 105 and recorded on a recording medium 108 wound on a transparent cylinder 113 in 2-dimension. The reflected light from the medium 108 traces an opposite optical path and the change in the contrast is detected by a detector 110 via an image forming lens 109. Thus, even when the mirror 106 and the lens 105 are driven by a motor 107 at a high speed, no friction with the medium 108 is caused, high speed scanning is attained by a minute spot and the record ing with high density large capacity is attained.

Title: Antilock braking device
Inventor: SHIRAKIGAWA TSUTOMU
IPC: B60T8/52
Filed: 1991-10-11
Abstract: PURPOSE:To perform an optimum braking at all times in response to noises from a road surface automatically by detecting the hydraulic pressure by a hydraulic cylinder, operating a control valve and controlling hydraulic pressure in the actuating cylinder of a caliper. CONSTITUTION:When a caliper 12 is minutely moved in an arrow direction by noises from a road surface in a moment, hydraulic pressure in a hydraulic cylinder 16 is heightened and simultaneously another hydraulic pressure in a liquid chamber 57 is also enhanced. Since a braking fluid will not flow into a liquid chamber 56 only through a small hole of a variable orifice 59, however, an upper side movement of a slide valve 48 becomes to be so minute. In contrast with this, in the case where it is moved momentarily to the caliper 12 in the reverse direction to the arrow direction by the noise, the orifice 59 opens, but because of providing for a relatively narrow passage 59, a movement of the slide valve 48 also becomes lessened. Since the variable orifice 59 and the passage 59a both have a structure as an orifice, even if there are noises on the road surface, no unpleasant feeling is given to a driver or the like.

Title: Reproducing device
Inventor: FUKATSU TSUTOMU
IPC: G11B27/10
Filed: 1985-12-27
Abstract: PURPOSE:To retrieve information recorded in each area in a short time with no additional large-scale device, by successively changing reproducing areas in a mode in which the reproduction of information on a recording medium and high-speed running of a tape are repeated. CONSTITUTION:When an information retrieving instruction is given from an operating section 11, a system controller 12 starts the reproduction of CH 1 by setting data (n) for area designation to '1' and instructing a capstan control circuit 20 to start normal running and discriminates whether or not audio signals are recorded in a designated area by confirming the output of an RF detecting circuit 23. When the audio signals are recorded, the system controller 12 performs similar operations on CH 2 by counting up the data (n) by '1' after performing reproduction for 5sec. When the 5sec reproduction is completed to CH 6, the system controller 12 closes a gate circuit 16 by releasing the area designation by an area designating circuit 13 and, when 18sec have passed after starting the high-speed running of a tape, performs the above-mentioned operations by completing the high-speed running of the tape. Therefore, retrieval of the information of all channels becomes possible by running a tape only and no additional hardware is necessary.

Title: Sorter controlling method
Inventor: TAMIYA YOSHIYUMI
IPC: B65H39/11
Filed: 1986-12-11
Abstract: PURPOSE:To prevent waste in copying by distributing copied sheets to a plurality of bins, and subtracting the difference between the number of sheets accommodated in the bins and the number of sheets fed from a copying machine from the number of uncopied sheets, in case a jam stops feeding. CONSTITUTION:Various copied sheets are received from a copying machine 3, and distributed to a plurality of bins and accommodated for binding. The number of sheets accommodated in each bin are counted and informed to the copying machine 3. If for ex. sheets 1-17, 1-18 on which No.1 original is copied have caused a jam, the subsequent sheet 1-19, 1-20 whereon No.1 original is copied and which have been sent off from a sheet feed table already and also sheets 2-1-2-3 whereon No.2 original is copied are exhausted to an exhaust tray 11 automatically. When jam is solved, the sheets exhausted onto the exhaust tray 11 are hand-fed 15 for distribution to bins in a sorter 1. The difference between the sum number of sheets accommodated in all bins and the number of sheets fed from the copying machine is subtracted from the number of uncopied sheets. This prevents wasteful double copying on the sheets exhausted onto the tray 11.
