Title: Composite material
Inventor: HARUTA SHINSUKE
IPC: C04B35/00
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a PTC thermistor material having an excellent PTCR property with a low resistance in a steady state, by employing a composite structure such that a metal and/or an alloy in which volume reduction due to melting occurs is dispersed in an insulator material. SOLUTION: A composite material has a composite structure such that metal and/or alloy particles are dispersed in an insulator material at a low temperature, and the metal particles or alloy particles are connected with each other at a certain proportion. In this state, since a conductive path is formed between the metal particles or alloy particles, a low resistance is exhibited. Next, as the temperature is raised, the dispersed metal or alloy particles change from the solid state to a liquid metal near the melting point. Thus, sudden volume reduction occurs and the resistance suddenly increases. As this insulator material, Ta2 O5 , PbTiO3 -PbZrO3 , boro-silicated glass or the like is employed. As the metal or alloy dispersed in the insulator material, a metal such as Bi, Sb, Ga, Ge, Si or the like, or an alloy such as Bi-Pb-Sn, Bi-Pb-Sn-Sb or the like is employed.

Title: Protection of mold in injection molding machine and protection device
Inventor: NARUSE TOSHIO
IPC: B29C45/67
Filed: 1987-10-27
Abstract: PURPOSE:To stop a mold closing through an early detection in case that a strange substance is caught in a molds and prevent the damage to the mold, by detecting a mold closing pressure acting on a mold clamping mechanism during the mold closing process and giving a warning when the mold closing pressure is higher than a preset value. CONSTITUTION:When a strange substance such as runner, flash etc., is attached on the parting face of mold pieces 6 and 7, this strange substance S is caught between the mold pieces 6 and 7 and the movement of a movable plate 5 is restricted before the mold closing process is finished. In this case, a mold closing pressure P acting on the rear chamber 9a of a mold closing cylinder increases. This pressure P is detected by means of a pressure detector 19 and entered into a comparator 20. Therefore, when the pressure P increases up to the strange substance detecting pressure calculated by a calculator 21, the calculator 21 gives an output signal. Then, by means of the output signal from the comparator 20, a warning is given from a warning device 25, and at the same time a conversion to the neutral state in a directional control valve 12 takes place to stop the mold closing.

Title: Logic ic with memory built-in
Inventor: TANIGUCHI KAZUO
IPC: G11C11/401
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for test by sending the signal designated by a switching signal in input signals for memory test and, on receiving plural bit output signals of the memory array, by outputting one bit output signals to the output terminal for memory test. SOLUTION: A signal from a node BITOR brings the selectors 6i, 6i,... on each input side to the switching conditions which outputs the second input signal In2. When a data signal for memory test is inputted from the input node ORIN for memory test, a signal which shows the result of bit-compressed one bit test corresponding to input signal of plural bits is outputted from the output node OROUT. And depending on whether the output value expected in accordance with input is obtained or not, the quality of memory is judged. Since only three terminals are needed for the terminals for memory test only and a bit-compressed memory test is carried out by a bit-compression circuit 7, the required time is reduced compared with tests performed for every bit.

The hot water is circulated by the circulating pump 15 only for a specific time t2 after reaching the specific temp. to measure the hot water temp. T2. The amount of the remaining hot water is computed from the quantity of heat of a burner 12 required for the additional heating, the amount of heat radiating by outside air temp., the degrees of raised temp., etc., according to a specified procedure. When the amount of the remaining hot water is short of the required amount in the bathtub 2, the hot water is supplied from a hot water supply part 30 to make up for the shortage.

Title: Image forming device
Inventor: MIURA KUNIYUKI
IPC: G03G15/08
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To exactly predict toner consumption by using a field effect transistor repeating on/off by accurately following analog image data. SOLUTION: In this image forming device, the field effect transistor 32 is used as a means for controlling a current in accordance with image data. The transistor 32 applies the current to a capacitor 36 following the analog image data which is intermittently switched to a high state and a low state. Therefore, the toner consumption is exactly predicted from charge amount charged to the capacitor 36. Since toner supply amount is decided not only based on the charge amount charged to the capacitor 36 but also referring to the detected value by a toner density detection means 22, the toner 28 is prevented from being supplied too much or too little, so that developer 20 is always filled up by the proper amount of toner 28. As a result, a high-definition image without fogging is obtained.

Filed: 1988-10-25
Abstract: PURPOSE:To make the manufacture easier and to make it possible to sustain a corona discharge stably for a long period by providing a platinum coverage layer further on the surface of a gold coverage layer. CONSTITUTION:A gold layer 2 is provided on the surface of a tungsten core wire 1, and furthermore, a platinum coverage layer 3 is provided on the surface of the gold coverage layer 2.
