Title: Optical device, optical head and information reproducing device using them
Inventor: YAMAMOTO HIROYUKI
IPC: G11B7/09
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical device which can condense a very small spot. SOLUTION: Incident light L is made incident on an optical device 1 from a light incident surface 1c. Then, the optical path thereof is radially dispersed by a first mirror surface 1a and reflected on a second mirror surface 1b. Additionally, it is converted to the annular beam L' and guided to an objective lens 2. The beam L' is passed through the lens 2 and condensed at the lower plane surface of an SIL 3. The annular focused light guided to the SIL 3 at this time is made incident, so as to form a critical angle or more with respect to the plane surface of the SIL 3, totally reflected on a boundary surface, and then returned. Thus, the light transmitted through the vicinity of the centers of the lens 2 and the SIL 3 is eliminated and only proximity-field light permeates through the vicinity of the center of the SIL 3.  For example, when the proximity-field light is detected by a probe, the external light other than the proximity-field light guided to the probe is eliminated, and the noise of the light to be detected is reduced. In addition to it, the beam spot becomes smaller than the normal condensing spot due to the effect of super image dissection.

Filed: 1993-01-27
Abstract: PURPOSE:To eliminate the need for LAN terminal equipments whose number is equal to connected number and to facilitate construction of network environment by allowing a device for pseudo plural terminal equipment for a LAN to simulate plural LAN terminal equipments. CONSTITUTION:When a network program of a device 2 for pseudo plural terminal equipment for a LAN is started, a main body CPU 20 gives a notice to a LAN adaptor 21. The adaptor 21 receives all destination data from a LAN 3 based on a simulation command, inverts its own station address and an opposite station address of network definition, collates a source address of all the received destination data, and when the addresses are coincident, the received data are transferred to the CPU 20 to set the address of the opposite station to the address 'A' to make communication with the LAN server/host 1. Thus, a terminal equipment 2 of a LAN executes the same processing as LAN terminal equipments 2a from the address 'n' to the address '02'.

Title: Fuel injection controlling apparatus for internal-combustion engine
Inventor: SASAKI TAKEO
IPC: F02D41/34
Filed: 1983-01-26
Abstract: PURPOSE:To enable to supply fuel at a rate required by an engine in a reliable manner, by keeping the driving period of a fuel injection valve longer than a prescribed value by lowering the fuel injection valve driving frequency when the calculated period for driving the fuel injection valve becomes lower than a prescribed value. CONSTITUTION:When a throttle valve 3 is almost completely closed in the state that the speed of rotation of an engine 1 is high, that is, at the time of deceleration of an automobile, the output of a pressure sensor 2 is lowered, so that the driving period of a fuel injection valve 5 calculated by an arithmetic circuit 7 is decreased to a small value lower than the operational range of the fuel injection valve 5. In this state, a time-period comparing circuit 21 judges whether the calculated value of the driving period is smaller than a prescribed value stored in a minimum-value memory circuit 20 or not. In case that the calculated value is smaller than the prescribed value, the frequency of the output signal of a rotation sensor 4 is divided to 1/2, and the frequency-divided signal is applied to an output circuit 8 as a trigger signal. Thus, the driving frequency of the fuel injection valve 5 is reduced to 1/2.

IPC: A23C9/142
Filed: 1981-02-02
Abstract: Non-phosphorylated peptides and phosphopeptides useful as alimentary products or medicaments are produced by proteolytic enzyme hydrolysis of a casein-based material. Membrane ultrafiltration is used to separate phosphopeptides which are retained by the membrane in a retentate from the non-phosphorylated peptides which pass through the membrane in an ultrafiltrate. The phosphopeptides in the retentate are disaggregated and are subjected to further membrane ultrafiltration where the phosphopeptides pass through the membrane and are separated from the enzyme. The non-phosphorylated peptides have nutritive value and can be used to form compositions for providing nutrition. The phosphopeptides form salts, which have dietetic uses, with macroelements such as calcium and/or magnesium and/or oligoelements such as iron and zinc.
