Abstract:
An ultrasonic probe including a piezoelectric vibrator configured to transmit and receive ultrasonic waves, an acoustic lens configured to focus the ultrasonic waves and an acoustic matching layer arranged between the piezoelectric vibrator and the acoustic lens and configured to modify acoustic impedance from the piezoelectric vibrator to the acoustic lens. The acoustic matching layer includes a first region arranged at center areas along a direction of transmitting and receiving of the ultrasonic waves, a second region arranged between the first region and the piezoelectric vibrator and having a rate of change of acoustic impedance which is less than rate of change of acoustic impedance of the first region and a third region arranged between the first region and the acoustic lens, and having a rate of change of acoustic impedance which is less than a rate of change of acoustic impedance of the first region.
Abstract:
A tray set composed of a first tray and a second tray, wherein the first tray having a plurality of depressed portions in which sushi toppings can be placed and which each has a shape having a depth so as to fill it with the sushi topping and a portion of a lump of rice seasoned with vinegar. The first tray is provided with a plurality of holes on the bottom so as for liquid dropped or oozed out from the toppings to be discharged therethrough. The second tray is arranged such that it can be laid under the first tray and the liquid discharged from the first tray can be received by a depressed face, and a plurality of projections are formed continually and integrally with the depressed face and the plurality of the projections are disposed so as to be engageable with the holes of the first tray and to project through the holes inside the first tray, when the second tray is laid under the first tray. The projections assist in separating the sushi from the tray. The tray set and the process for preparing sushi by using the tray sets do not require any experience and skills for preparing sushi and can prepare a number of sushi with high efficiency and at cheaper costs in a short time.
Abstract:
For example, a blended composition is produced first by letting a monomer composition, mainly composed of alkyl (meth)acrylate and including a compound having a plurality of polymeric groups within a molecule, contain microscopic particles, such as carbon black, having an average primary particle size in a range between 1 nm and 200 nm, and then the blended composition is polymerized. Consequently, it has become possible to produce inexpensive crosslinked elastomer having excellent physical properties, such as small creep (low creep) in compression set, tensile elongation set, etc., and excellent mechanical strength, such as tensile break strength and tensile break elongation, in a simple procedure omitting the post-crosslinking step at a high-level productivity while saving energy and time spent in the kneading step.
Abstract:

The dye is manufactured with one member selected from the class consisting of a combination of (A)+(B) groups, a combination of (A)+(C) groups, a combination of (B)+(C) groups, and a combination of (A)+(B)+(C) groups, wherein (A) represents a group of quinizarine compounds, (B) represents a group of anthraquinone compounds, and (C) represents a group of phthalocyanine compounds.
Abstract:
In a safety shoe provided with a toecap, a vamp, an insole, and a two-layer structure sole, the a two-layer structure sole includes an outsole part comprising a high hardness rubber material and a midsole part, laminated in the above outsole part, comprising a low hardness sponge rubber material and has a heel part. The outsole part is fused integrally with the midsole part by vulcanization molding, and the upper circumferential edge of the outsole part is fused integrally with the lower circumferential edge of the vamp by the vulcanization molding described above. Since the outsole part in a side in contact with the ground has a high physical strength and is excellent in an oil resistance, a chemical resistance and a heat resistance, and the midsole part in an inner side has a cushioning property, the shoe is less liable to bring about fatigue even after wearing it for a long period of time. Further, a weight of the whole safety shoe can be lightweight, and a durability of the whole safety shoe can be elevated.
Abstract:
A novel narrow-band communication apparatus comprises a digital signal processor for demodulating the output from a receiving section and outputting a modulation signal for an audio input, an electric field strength detector section for detecting electric field strength in the output from the receiving section, an indicator for indicating whether the narrow-band communication apparatus is in a receiving mode or in a transmission mode, and a power controller for controlling supply of power to, or an operating state of specified portions of, the narrow-band communication apparatus according to the output from the electric field strength detector as well as from the indicator.
Abstract:
A toner density control device for an electrophotographic copier, facsimile apparatus, laser printer or similar image forming apparatus of the type forming an image by depositing a toner on an electrostatic latent image. The device has two sensing circuits, i.e., a toner density sensing circuit and an image density sensing circuit. When one of the two sensing circuits fails, a toner is supplemented in response to an output of the other or normal sensing circuit. When the failed sensing circuit is restored to normal, the toner supply responsive solely to the other sensing circuit is cancelled so that both of the two sensors join in the toner supply control. When both the toner density sensors and the image density sensing means fail, the image forming apparatus is automatically disabled with the failure being displayed.
Abstract:
A method for molding stick cosmetic, which comprises:Closely fitting a molding block into a vertically extending annular member formed around a container charged with a liquid feed composition for solid cosmetics, said molding block having therethrough a plurality of longitudinal slots which are open at both ends;filling said liquid feed composition into said longitudinal slots; and, thereafter,solidifying and drying the thus filled liquid feed composition.
Abstract:
An image reading apparatus includes a casing, a light emitting section, a substrate, a support member, and a light guide. The light emitting section includes plural point light sources disposed in a row. The light emitting section is installed to a first face of the substrate. The support member is installed to the casing and supports a second face of the substrate at a projection portion where a position of the light emitting section is projected at the second face of the substrate. The light guide is installed to the casing adjacent to the light emitting section, and guides light from the light emitting section to a read-face.
Abstract:
A ultrasonic probe has a plurality of piezoelectric transducers arranged in the array direction. Each piezoelectric transducer has a piezoelectric element which vibrates in the thickness direction. A signal electrode is formed on the lower surface of the piezoelectric element. An earth electrode is formed on the upper surface of the piezoelectric element. Inside the piezoelectric element, a plurality of non-piezoelectric elements are arranged along the lens direction. Each non-piezoelectric element does not come in contact with the signal electrode and the earth electrode.
