Title: Image forming device
Inventor: SASAKI HIROSHI
IPC: G03B27/54
Filed: 1986-01-20
Abstract: PURPOSE:To prevent operator's eyes from being dazzled by mounting a polarizing filter which provides polarizing operation for a light source emitting polarized light in one direction inside an original cover, and confirming an original mounting state from above a transparent cover. CONSTITUTION:The light source 20 consists of a laser diode which has a polarizing direction as shown by an arrow (a) and the polarizing filter 1a having an angle of polarization as shown by an arrow (b) is provided inside the original cover 1 to transmit only polarized light perpendicular to the light source 20. A reflecting plate 5c is provided above an original detection sensor 5b at the rear part of a copying machine and light from an LED lamp group 5a is made incident on the sensor 5b. When an original is mounted and the cover 1 is closed, the light from the lamp 5b is cut off by the original to detect the original size and original setting state, and a blank lamp on a photosensitive body is turned on to prevent toner from sticking. Further, the light of the light source is not transmitted through the transparent cover 1 through the operation of the polarized light of the light source and the filter, so the operator's eyes are never dazzled.

Abstract: PURPOSE:To measure the accurate amount of sky infrared radiation by directing two kinds of detector consisting of mirrors which have sunshine reflection factors nearly equal to 1, differ greatly in only the emissivity of infrared rays, and small variations in emissivity with wavelength in an infrared range to the sky and ground surface, and fitting a mirror which has a sunshine reflection factor nearly equal to 1 and large infrared emissivity under the detector directed to the ground surface. CONSTITUTION:A mirror is formed by using a low iron content glass with extremely high sunshine transmissivity as a substrate, vapor-depositing metal which has a high reflection factor to white and weather resistance such as aluminum, and further vapor-depositing a weather-resisting protection film. A film of ''Teflon'' or acryl, etc., is stuck on the surface of the glass so as to reduce variation in the demultiplexing absorptivity in the infrared range when this mirror is used as a reverse surface mirror. Several - tens of thermocouples are arrayed between a surface mirror 1 and a reverse surface mirror 2 which adjoin to each other, and the temperature difference generated between the surface mirror and reverse surface mirror is outputted in the form of a voltage. Similarly, a thermocouple arrays is fitted between a surface mirror and a reverse surface mirror 4. This infrared detection part is installed horizontally and a sunshine reflecting mirror of large area is fitted horizontally under it. The sunshine reflecting mirror uses the same reverse surface mirror that the infrared detection part uses.

Title: Magnetic head
Inventor: HIYANE MASAO
IPC: G11B5/127
Filed: 1981-01-29
Abstract: PURPOSE:To achieve wider write-in and narrower readout, by closely locating each submagnetic circuit at both sides of a main magnetic circuit so that one air gap is arranged almost on the same line of the air gap of the main magnetic circuit. CONSTITUTION:A lower magnetic substance layer 10 and an upper magnetic substance layer 20 constitute a main magnetic circuit with one air gap 30, and the lower magnetic substance layer 10 and two upper magnetic substance layers 21, 22 constitute submagnetic substance circuits having two each air gaps. Each submagnetic circuit is arranged near both sides of the main magnetic circuit so that the air gaps 31, 32 are arranged at almost on the same line as the air gap 30 of the main magnetic circuit 30. Since each submagnetic circuit has one air gap at an opposite side in addition to the air gaps 31, 32, the magnetic resistance is greater than that of the main magnetic circuit and electromagnetic  induction coupling with a coil 40 is weaker than that of the main magnetic circuit. Thus, a reproduction signal at readout of the submagnetic circuits is negligibly smaller than that of the main magnetic circuit, allowing to make wider  write-in and narrower readout for the magnetic head.

Filed: 1992-01-28
Abstract: A novel conjugate vaccine comprising partially hydrolyzed, highly purified, capsular polysaccharide (Ps) from Streptococcus pneumoniae bacteria (pneumococci, Pn) linked to an immunogenic carrier protein, is produced by a new process. The conjugate is useful in the prevention of pneumococcal infections. Vaccines comprising a mixture of from one to ten different pneumococcal polysaccharideimmunogenic protein (Pn-Ps-PRO) conjugates induce broadly protective recipient immune responses against the cognate pathogens from which the polysaccharide components are derived. Young children and infants younger than 2 years old, normally unable to mount a protective immune response to the Pn-Ps alone, exhibit protective immune responses upon vaccination with these Pn-Ps-PRO conjugates.

Title: Out-of-step isolation device for power system
Inventor: KURIMOTO SHIGENORI
IPC: H02H3/48
Filed: 1993-01-29
Abstract: PURPOSE:To prevent a local generator from being unnecessarily isolated by discriminating between obvious out of steps of the generator and probable ones. CONSTITUTION:A setting unit 7 previously defines a given region where the resistance and reactance components of power flow impedance of a power system is in proximity to zero as the first region, and a region where the reactance component is larger than that of the first region as the second region. An input unit 8 sequentially samples the current and voltage of the power system. An operation unit 9 computes power flow impedance based on the sampled current and voltage to obtain an impedance locus. Only when an impedance locus passes through the second region and does again a specified time later, the local generator is judged to be out of step. Thus the power system is isolated at a system isolation unit 10 only when it is certain that the local generator is out of step.
