Ethyl (1R,6S)-2,2,6-trimethylcyclohexanecarboxylate represented by formula (1) ##STR1## is disclosed. Also, an aroma chemical composition containing the same and a process of the production of the same are disclosed.
摘要:
A perfume composition comprising 2,4-di-tert-butylcyclohexanone is disclosed. This perfume composition has a highly preferable and fresh scent and thus widely available in, for example, perfumes, cosmetics, hygienic products and medicines. The 2,4-di-tert-butylcyclohexanone, which may be in the form of either a cis-isomer, a trans-isomer or a mixture thereof, is highly safe and stable.
摘要:
A convertible vehicle body structure having a rigid front roof panel covering the front top portion of the passenger compartment and a rear roof panel covering the rear portion of the passenger compartment. The front roof panel is supported by an inverted U-shaped swingable pillar and the rear roof panel is mounted on the rear body structure through mounting arms. The front and rear roof panels are retracted in the rear body section in a fore-and-aft jaxtaposed relationship.
摘要:
A convertible vehicle body including a swingable pillar structure for supporting a front roof panel movably between an extended position and a retracted position. A rear side panel or a rear fender panel assembly has a rear side glass panel and a side door has a transparent glass panel. The rear side glass panel has a front edge which is located outside the pillar structure and in an abutting relationship with a rear edge of the transparent glass panel in the side door. Thus, the pillar structure is covered by the transparent glass panels to provide a good appearance.

A workbook is provided for the study of preparing not only an expected answer from a given problem but also an expected problem from a given answer. This workbook comprises a first page provided with a problem section and an adjacent expected answer guide section, adjacent to each other, a transparent second page superimposable upon the first page, and an opaque sheet adapted to be inserted between the first and second pages. The second page is provided with an answer section, and an expected problem guide section both of which are respectively located at corresponding positions above the expected answer guide section and the problem section when the second page is superimposed upon the first page.
摘要:
A numerical sequence board game. The numerical sequence board game includes a gridded board and corresponding playing pieces. The hexagonal-shaped playing pieces may be placed on corresponding hexagonal grids on the gridded board during game play. Each playing piece may include numerical indicia that can be used to form numerical sequences with other playing pieces, wherein the numerical sequences may be formed in one or more directions on the gridded board.

Provided are a communication device, a communication method, and a recording medium that can reduce concentration of a load on one of wireless channels. A communication device that uses wireless channels includes: acceptance means for accepting, from a different communication device and through one of the wireless channels, channel information that indicates wireless channels that can be used by the different communication device; control means for selecting, as a wireless forwarding channel for first information, a wireless channel, which is different from a wireless transmission channel for transmitting the first information, from among the wireless channels that are indicated by the channel information, and for adding second information indicating the wireless forwarding channel to the first information; and transmission means for transmitting the first information provided with the second information by using the wireless transmission channel.
摘要:
A data carrier 2 is provided with a comparator 41, a capacitor 42, a comparator operation adjustment resistor 43, a resistance voltage divider circuit 44 and a reactive-current resistor 45. The capacitor 42 is disposed between the cathode of a photo-diode (PD) 21 and the minus input terminal of the comparator 41. The comparator operation adjustment resistor 43 is disposed between the plus terminal of a primary battery 271 and the minus input terminal of the comparator 41. The resistance voltage divider circuit 44 is constituted by a series connection of voltage dividing resistors 441 and 442. One end of the resistance voltage divider circuit 44 is connected to the plus terminal of the primary battery 271. The junction between the voltage division resistor 441 and the other voltage division resistor 442 is connected to the plus input terminal of the comparator 41.
摘要:
In a parts assembly system which assembled subsidiary parts with main parts, the main parts are conveyed through a first conveying path to an assembly robot provided along the first conveying path, and the subsidiary parts are supplied through the first conveying path to stockers provided along the first conveying path. In consequence, the travel space of the conveying cart is saved.
