摘要:
A tobacco smoke filter includes a corrugated tape-like wrapping which, together with an outer perforated or otherwise air-permeable paper, defines a set of longitudinal grooves. Each of the grooves includes a blocking member, so as to inhibit direct smoke flow through the grooves and promote a ventilation effect. The blocking members in each groove are longitudinally staggered from one groove to the next to simplify the production of the device.

Disclosed is a technology that prevents a part of a touch panel-equipped display displaying an ultrasonic tomographic image from getting dirty with a fingerprint or scratch when using a drag operation to change the content of the ultrasonic tomographic image displayed on the touch panel-equipped display. According to this technology, the display screen is divided into an ultrasonic image area A1 which displays an ultrasonic image P and an operating part display area A2 which displays buttons (Fov, Pos, ROI, and Dop) for selecting a change to be made in the ultrasonic image P. The operating part display area A2 has a touch panel, and when a finger F selectively touches one of the displayed buttons and is dragged, the displayed image P of the ultrasonic image area A1 is changed on the apparatus side according to the selected changes and drag direction.

Disclosed is an organic-inorganic composite material obtained by chemically modifying a microorganism-derived ceramic material with an organic group, and a process for producing the organic-inorganic composite material. The process is characterized by reacting a microorganism-derived ceramic material with at least one compound selected from the group consisting of silane coupling agents represented by formula (1), silane coupling agents represented by formula (2), and titanate coupling agents represented by formula (3). The organic-inorganic complex can be used in applications for immobilized catalysts and immobilized enzyme catalysts.

An ultrasonic diagnostic apparatus includes: a plurality of vibration elements (1) that transmit and receive an ultrasonic beam; a plurality of transmission circuits (2) that are connected to the respective vibration elements and output a transmission driving signal to be used for driving the vibration elements; and a transmission power source (3) that supplies electric power to the transmission circuits. The ultrasonic diagnostic apparatus further includes: a pulse detection unit (21) that detects a transmission signal to be used for generating the transmission driving signal; an electric power measurement unit (20) that detects an amount of electric power supplied to the transmission circuits as a whole; a distribution calculation unit (24) that calculates an amount of electric power distributed into each of the vibration elements based on outputs of the pulse detection unit and the electric power measurement unit; and a power distribution derivation unit (22) that derives electric power having been supplied to each of the plurality of vibration elements based on an output of the distribution calculation unit, wherein the transmission driving signal is controlled based on the power distribution derived in the power distribution derivation unit. With this configuration, it is possible to provide a more compact and highly reliable ultrasonic diagnostic apparatus capable of performing a temperature monitoring that detects local heat generation of the vibration elements based on the actual transmission power by using a circuit with a reduced number of components.

A novel optical-isomer separating agent for chromatography is provided which has, as a chiral selector, a macrocyclic amide compound having the ability to function as a chiral shift agent. The optical-isomer separating agent for chromatography is formed by bonding, with a carrier by chemical bonding, a specific ring structure containing an asymmetry recognition site, an amide group as a hydrogen-bond donor site, and a hydrogen-bond acceptor site.
