Title: High frequency testing device and electronic equipment using it
Inventor: OTSU AKIHIKO
IPC: H01R13/703
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To efficiently transmit a ultra high frequency signal in a normal condition and temporarily shut off and switch a signal path, if required, in a small-scale and low-profile structure at a lower manufacturing cost by providing a pair of contact members, a movable member and a conductive shell. SOLUTION: In a high frequency testing device 10, a movable member 60 is energized upward in a normal condition by an elastic material 70 and contact portions 23, 33 are short-circuited between a pair of contacts (contact members) 20, 30 into a conductive condition by the member 60. A high frequency signal transmission path is formed with these contacts 20, 30 and a conductive shell 50 to encircle these at a constant space. When a tesing probe 80 probes (thrusts and contacts), an outer conductor 81 for the probe 80 contacts the top of the shell 50. A center conductor 82 contacts and thrusts downward the member 60 via an access opening 51 and the portion 33 contacts a non-conductive area 65, so that a circuit between the contacts 20, 30 is opened and the member 20 is connected to the conductor 82 for the probe 80 for probing with a measuring instrument, if required.

IPC: H01L29/73
Filed: 1990-07-26
Abstract: PURPOSE:To speed up the operation speed of a bipolar transistor in vertical structure and enhance the integration degree of SRAM by constituting a second semiconductor region which is the same conductor type to a first semiconductor region and formed substantially with the same impurity concentration at a joint section between a gate electrode of drive MISFET for a semiconductor region on one side and a base body. CONSTITUTION:An n type semiconductor region (pedestal collector region) 20, which is the same conductor type to an intrinsic collector region and formed with high impurity concentration, is set up between a p type base region (p type semiconductor region 11) of an npn type bipolar transistor Tr in vertical structure and an intrinsic collector region (n type well region 5) in an n type collector region. At the same time, an n type semiconductor region 20, which is the same conductor type to the n type semiconductor region 20 and formed substantially with the same impurity concentration, is set up at a joint section between a gate electrode 14 of drive MISFETQd in an n<+> semiconductor region 17 on one side of a transistor MISFETQt for SRAM memory cell and a base body (p type well region 6). This construction makes it possible to increase the amount of information accumulated charge of a memory cell and enhance alpha ray soft error pressure resistance. As a result, it is possible to speed up the operation speed of a hybrid semiconductor integrated circuit device and hence enhance the degree of integration.

Title: Method and apparatus for measuring tensile force distribution of metal band plate in plate-width direction utilizing vibration
Inventor: YAMAMOTO TETSUO
IPC: B21C51/00
Filed: 1992-07-27
Abstract: PURPOSE:To make it possible to measure the tensile force of a band steel in the direction of the plate width regardless of the kinds of material without contact by generating vibration in the band plate of metal, on which tensile force is applied, and measuring the distribution of the displacement of vibration at a plurality of points. CONSTITUTION:Vibration is generated in a band steel 9, which is running from rolls 2 when the band steel 9 is rolled. The distribution of the displacement is investigated. The distribution of the tensile force in the plate-width direction can be obtained by applying the distribution to any of the classified shapes of the distributions. Thus, the measurement can be performed without damaging the surface of the band steel 9 without contact. Since the measurement of the displacement is performed based on not the absolute value but the relative value, accuracy is not required in attachment of a displacement gage.

Filed: 1982-11-16
Abstract: PURPOSE:To improve charge controllability and durability and to obtain a sharp image by incorporating an electron-donative material having a specific ionization potential value in a toner and coating a carrier with a styrene/acrylic resin. CONSTITUTION:An electron-donative material having <=7.8eV ionization potential value, for example, triphenyl amine, is incorporated as a charge control agent in a toner, at about 0.1-10wt% basing on the weight of the binder resin. A carrier is used after a styrene/acrylic resin (SA resin) is coated thereon. The electron- donative material is incorporated in the toner and the carrier layer is formed of the SA resin having relatively high electron acceptivity in such a way and therefore the donation and acceptance of the electric charge between the electron- donative material and the carrier are smoothly accomplished, whereby the uniform electrostatic charge is impressed over the entire part of the developer and the sharp image is obtd. without filming of the toner. The durability of the developer is excellent. Such developer is suitable for various types of photosensitive bodies having negative electrostatic charging property, such as a photosensitive body having an a-Si vapor deposited layer.

Filed: 1983-10-25
Abstract: PURPOSE:To suppress closing of a nozzle and to stabilize continuous operation by acting the DC magnetic field to the molten metal flow passing through the inside of the nozzle and preventing sticking of an inclusion to the inside surface of the nozzle. CONSTITUTION:The molten metal 2 in a tundish 1 flows through the inside of a nozzle 3 and is poured into a casting mold 4.
