Title: Additive for casting
Inventor: KAWASHIMA TOMOO
IPC: B22C1/16
Filed: 1994-02-02
Abstract: PURPOSE:To provide an additive for casting capable of improving the quality of cast products by a relatively inexpensive material cost. CONSTITUTION:This additive is produced by mixing about 20% gilsonite with starch which is extracted from the high molecular layers of the epidermis of corn produced in the Unzted States and is subjected to an aphatization treatment. As a result, the amt. of the additive to be used is decreased and the water holding power is increased by about twice as compared with the conventional additives. Kneading under a low water content is possible and since the surface stability of the cast products is improved, the material cost is reduced and the quality of the cast products is improved.

Title: Magnetic recorder
Inventor: HAGIWARA MOTOHARU
IPC: A61B5/336
Filed: 1991-01-31
Abstract: PURPOSE:To avert waveform distortions and to reduce electric power to be consumed as well as to execute recording of cardiographic signals with high accuracy over a long period of time by converting the cardiographic signals into digital signals, circulatively accumulating the digital signals into plural buffer circuits and intermittently recording these signals at prescribed timing.

Title: Semiconductor device and manufacture thereof
Inventor: SAWADA KOJI
IPC: H01L21/285
Filed: 1995-02-21
Abstract: PURPOSE: To lessen a conductive plug of tungsten in electrical resistance. CONSTITUTION: A lower conductive layer 51 and an upper conductive layer 54 are electrically connected together by a conductive plug 60 plugged in an opening 53 provided to an insulating layer 52. The conductive plug 60 is formed of tungsten which is an axis-oriented polycrystalline body whose crystal axes are oriented along the axis of the opening 53. That is, no crystal grain boundary is present along the axis of the opening 53 in the conductive plug 60, so that most of a current which flows through the conductive plug 60 flows without passing through the crystal grain boundary. In result, the conductive plug 60 becomes low in electrical resistance. As the conductive plug is low in electrical resistance, the opening can be lessened in area, and a device is capable of being much micronized in size.

Title: Preventing circuit for malfunction of cd player
Inventor: SAYAMA MASANOBU
IPC: G11B7/09
Filed: 1986-02-17
Abstract: PURPOSE:To surely prevent such a malfunction as a CD player works again with rise of the voltage by inhibiting application of the servo signal to an optical pickup circuit from a system control circuit for a prescribed period of time despite a fact that the battery voltage level rises up in response to reduction of the load current after reduction of the battery voltage level. CONSTITUTION:When the voltage of a battery 12 drops less than the minimum available level, a Zener diode 18 is inverted into a non-conduction state together with a detecting transistor TR16. Then the bias current flows to the base of the 2nd TR24 from a plus terminal 14 of a DC/DC converter 13 through a resistance 19, a diode 26 and a resistance 25. Thus the TR24 conducts and the 1st TR20 is biased to conduct with the 1st-3rd switching TR32, 34 and 36 set under the conduction state respectively. Here a capacitor 27 connected to the base circuit of the TR24 is charged. Thus the signal is never read out to a signal processing circuit 2.

Title: Nitric acid resistant austenite stainless steel
Inventor: ABAI RIYOUICHI
IPC: C22C38/40
Filed: 1978-03-22
Abstract: PURPOSE: To confer upon steel excellent resistance to high temperature liquid or gaseous nitric acid by including a specific amount of Si in extra-low carbon high- chrome type sustenite stainless steel.  
     CONSTITUTION: Two to five % Si is added to the sustenite stainless steel contianing < 0.0% C, < 6% Mn, 23 to 30 % Cr, 17 to 27% Ni, and < 0.4% N. The influence of hexavalent chromium having a relevance to the corrosion of austenite stainless steel by nitric acid is reduced by the addition of Si. Thus, the steel exhibits excellent nitric acid resistance even in a severe nitric acid atmosphere in the nitric acid manufacturing process.

Abstract: PURPOSE:To ensure that accurate liquid droplet discharge and application are performed and a defective finished product is prevented from generating to contribute to the improvement of economy by allowing liquid droplets from a first nozzle tip end to drop into the intake part of a nozzle to block a discharge aperture, and discharging the liquid droplets from the intake part to an outside using a compressed air. CONSTITUTION:In a method of allowing the liquid droplets Ld of a pressurized liquid Lp to drop to a discharge aperture 9 in a second nozzle 3 from a first nozzle 2 to block the aperture 9, and discharging the liquid droplets Ld' using a compressed air Ap guided into the second nozzle to an outside, the compressed air Ap is allowed to pass through an overflow path formed on the periphery of the tip part 5 of the first nozzle 2, so that the velocity of the compressed air Ap is accelerated to direct the air downward. After that, the liquid droplets sticking to the tip part 5 of the first nozzle are forced off by the negative pressure of the air generated following the downward blow of the compressed air. In addition, the liquid droplets are allowed to drop into the intake part of a discharge aperture 9 in the second nozzle 3 to block the discharge aperture 9, and the liquid droplets Ld' on the intake part are discharged to an outside by the compressed air Ap to be induced consecutively.

Title: System for preventing collision
Inventor: MASHIBA MINORU
IPC: H04Q1/20
Filed: 1983-02-28
Abstract: PURPOSE:To prevent collision between an incoming and an outgoing call by detecting the incoming call by both AC and DC supervision and catching a telephone line on the premise without the incoming call in an emergency communicating device. CONSTITUTION:When an incoming signal arrives, a station terminal L2 is inverted to positive polarity. Then, since a current flows to a photodiode PD until a capacitor C1 is charged, the current is extracted by a phototransistor PT, causing a one-shot circuit 23 to trigger, the signal is converted into a one-shot output Q having long pulse width, and the pulse is fed to a control section as the 2nd incoming detection signal RING2. The control section, when informing a receiving device, confirms the presence of any incoming call by the 1st and 2nd incoming detecting signals before catching a telephone line, and confirms further the hooking-on of the telephone set, and then catches the line.
