Title: Production of 3-bromobenzaldehyde
Inventor: MATSUURA SHINICHI
IPC: C07C45/63
Filed: 1987-08-25
Abstract: PURPOSE:To efficiently carry out reaction in obtaining the titled compound using 1,2-dichloroethane as a solvent and brominating benzaldehyde, by recovering solvents, reacting the recovered solvents with chlorine in the presence of a catalyst, obtaining the solvent (1,2-dichloroethane) and bromine from by- product of the solvent and reusing the solvent and bromine. CONSTITUTION:In obtaining 3-bromobenzaldehyde by reacting benzaldehyde with bromine in 1,2-dichloroethane in the presence of a brominating catalyst, 1,2-dichloroethane is partially converted into 1-bromo-2-chloroethane and 1,2- dibromoethane (used bromine does not come out of the system at all). The solvents are reacted with chlorine in the presence of a brominating catalyst so that 1-bromo-2-chloroethane and 1,2-dibromoethane regenerate. 1,2- dichloroethane and simultaneously produces bromine as a by-product. 1- Bromochloroethane and bromine are reused to give high-quality 3- bromobenzaldehyde in high selectivity and in high yield and economically.

Abstract: PROBLEM TO BE SOLVED: To prevent a high-speed/low-speed switching shaft-like body from being interlocked with the movement of a two-wheel/four-wheel switching shaft-like body by operating the two-wheel/four-wheel switching shaft-like body in a shaft length direction independently of the high-speed/low-speed switching shaft-like body to switch between a two-wheel drive state and a four-wheel drive state. SOLUTION: At the time of switching from a two-wheel drive state to a four-wheel drive state, a two-wheel/four-wheel switching shaft-like body 3 can be operated in a shaft length direction, in the direction of an arrow mark X1, independently of a high-speed/low-speed switching shaft-like body 4 without interlocking the high-speed/ low-speed switching shaft-like body 4. At the time of switching from the four-wheel drive state to the two-wheel drive state, the shaft-like body 3 can be operated in the shaft length direction, in the direction of an arrow mark X2, independently of the high-speed/low-speed switching shaft-like body 4.  That is, at the time of switching between the two-wheel drive state and the four-wheel drive state, the high-speed/low- speed switching shaft-like body 4 is impeded by parts 8a, 8b of an interlock 8 with stopper function so as to improve such inconvenience as interlocked with the movement of the two-wheel/four-wheel switching shaft-like body 3.

Abstract: PROBLEM TO BE SOLVED: To reduce loss of motive power and to restrain locking by providing a pump and a motor respectively synchronizing with a front wheel and a rear wheel and controlling each travelling state by using an opening regulating means provided between a first passage and an accumulator and a channel changing means provided to the side of a motor rather than the accumulator. SOLUTION: A pump (p) is connected to a motor (m) through first and second passages 2, 3, the motor (m) is linked to a rear wheel RT, and an accumulator 7 is connected to the first passage 2 through an opening adjusting means (change-over valve 5, control valve 6). Additionally, a channel changing means (change-over valve) 12 is provided to the side of the motor (m) rather than the accumulator 7. Thereafter, working oil is accumulated in the accumulator 7 opened to the first passage 2 by the pump (p), for example, by blocking the first passage 2 by the change-over valve 12 at the time of deceleration, opening the change-over valve 5 and the control valve 6. Furthermore, a regulator valve 17 is made to take partial charge of braking force by increasing capacity of the pump (p). At this time, braking force works on a front wheel FT increasing a load, and it becomes hard to lock.

Abstract: PURPOSE:To obtain a lightweight and highly efficient solar cell possessed of an antistatic function by a method wherein a surface electrode and an insulating reflection preventive film are provided onto an n layer of an n-p type InP solar cell, and a conductive film formed thereon and the surface electrode are electrically connected with each other. CONSTITUTION:An n-type layer 15 is formed on a p-type InP substrate 14, a surface cathode 17 composed of two layers of Pd and Ag is formed thereon in a comblike shape, and an anode 16 is formed on the whole rear side of the substrate 14. An insulating reflection preventive film 18 is provided onto the whole face of the layer 15, and an ITO film 19 is formed thereon as a conductive film. The film 19 is electrically connected with the electrode 17 as being in contact with the side face of the electrode 17, so that electrons accumulated at the conductive film 19 formed on the outermost face of the electrode 17 can be removed through the electrode 1. And, as an InP cell is excellent in radiation resistance and dispenses with a cover glass, the reflection loss and the absorption loss due to a glass and a bonding agent can be eliminated. By this setup, a lightweight and highly efficient solar cell possessed of an antistatic function can be obtained at a low cost.

Title: Metal halide lamp
Inventor: SHIMAOKA SEISHIN
IPC: C03C17/25
Filed: 1990-08-09
Abstract: PURPOSE:To obtain light of color temperature lower than the color temperature of light generated in a luminous tube by forming a visible-light selecting and absorbing film on the surface of a light transmitting cylinder. CONSTITUTION:An outer tube 4 made of hard glass has a luminous tube 1 and a light transmitting cylinder 2 built therein. The light transmitting cylinder 2 made of quartz glass surrounds the luminous tube 1, and it has its outer face formed with a visible-light selecting and absorbing film 3 which is made up of a paint film of silica group material containing a transition-element oxide. By the visible-light selecting and absorbing film formed on the surface of the luminous tube in this manner, part of visible light is prevented from its transmission through the luminous tube so as to lower its color temperature more by an optional value than that of light generated in the luminous tube. As a result of that, a metal halide lamp can be obtained with its low color-temperature light output, its excellent color rendering property and its satisfactory life property.

Thus, the information encoded between mutual facsimile equipment FX1 and FX2 is given and taken by the devices AD1 and AD2. In order to connect with respective FX1 and FX2 and a public telephone circuit network to the AD1 and AD2, a band transmitting means to provide a data MODEM at respective connecting edges is provided and in order to connect with concealing devices SC1 and SC2, first and second base band transmitting means such as a serial data transmitting means are provided. By such a constitution, without a cost rise, the concealment transmitter having large universal applicability is obtained.
