Title: Liquid transfer device
Inventor: SHIRAI SHIGERU
IPC: F23K5/04
Filed: 1988-06-10
Abstract: PURPOSE:To allow oil to be supplied without detaching a spout, and to securely stop a pump at a specified level by attaching a detachable adapter on the spout of No.2 liquid container so as to make the top of a discharge pipe of the adapter push down a valve body of the spout open, and providing a liquid detecting element inside a discharge pipe. CONSTITUTION:No.1 liquid container 16 is provided with a controller 19 above a pump unit 18. An adapter 20, that is detachable at a touch, is attached on a spout 23 of No.2 liquid container 22. The spout 23 is faced upward when supplying oil, and the top of a discharge pipe 30 is inserted into the opening of the adapter to push down a valve body 43. When the pump unit is started at this state, the liquid flows from a discharge port 38 as shown by the arrows with solid lines, and is transferred smoothly without spilling out. A liquid detecting element 32 contained inside the discharge pipe is an optical sensor provided with a prism 34, and the surface of the valve body 43 facing the prism is constituted so as to reduce an amount of returning reflection light that is emitted from the liquid detecting element and reflected by the prism. Therefore, when the liquid reaches the full level, the liquid detecting element and the controller operate to securely stop the pump unit automatically.

Title: Memory control signal supply circuit
Inventor: WASHI KAZUO
IPC: H04N7/01
Filed: 1984-07-13
Abstract: PURPOSE:To reduce a relative delay time dispersion between control signals to an extremely small amount by mounting a flip-flop in a memory substrate and waveform-shaping each control signal waveform with the aid of a reference clock for generating a memory control signal. CONSTITUTION:In terms of flip-flops 11 and 12, each memory control signal is waveform-shaped by on CK period with the aid of a reference clock for generating said signal. When it is inputted to each DRAM10, it becomes 1CK delayed signal compared with each memory control signal immediately after it is produced in a memory control signal generator circuit 13. However, the relative hourly relation between respective memory control signals, that is, row address strobe signal, column address strobe signal and address signal, is the same as that immediately after said signals are generated. Moreover, buffers 4-7, 13 and 14 can employ the IC with low power consumption at a low speed unless the relative delay time dispersion owned by each signal exceeds a clock one period.

IPC: G11B7/258
Filed: 1994-06-27
Abstract: PURPOSE:To make a reflecting layer hard to bring about scratches and abrasion by forming a reflecting layer comprising pigment and a polymer material on a transparent substrate in which the irregularities corresponding to an information signal are formed and containing nitrocellulose as the polymer material. CONSTITUTION:A pigment containing layer 3 comprising at least a pigment material and a polymer material is formed as a reflecting layer on a substrate 2 in which a recessed pit part 4 and a projecting land part 5 corresponding to an information signal, a guide groove and an address code pit are formed. In this optical information medium reading light beams LB radiated from the substrate 1 side are respectively reflected by the boundary surface 8 between the substrate 1 and the pigment containing layer 3 and by the boundary surface 7 between the pigment containing layer and air, and signal reproduction is performed by utilizing multiple interference. Therefore, the reproduction of a signal is performed by utilizing that the light beams are reflected by the boundary surface 7 between the pigment containing layer and air to cause multiple interference. When the faults of shape such as scratches and abrasion are brought about, the multiple interference of light falls into disorder and the signal reproduction is hindered, and however, nitrocellulose is used for the pigment layer 3 as a polymer material, thereby improving the characteristic of scratch resistance.
