Abstract: A digital telephone answering device (DTAD) that allows messages to be forwarded to certain internal mailboxes. Random access memory (RAM) is flexibly and dynamically controlled by a microprocessor or controller. Audio signals in the form of voice messages are digitized and stored in the RAM. Messages can be sorted and allocated to specific mailboxes and made retrievable by pressing a button assigned to that mailbox. Messages can also be moved or re-assigned from a common message area to a certain mailbox or mailboxes. Outgoing messages are also stored in RAM and can be of sufficient number to have an outgoing message correspond to each incoming message storage area. The normal message recording and message playback functions of the DTAD may be activated after the call has been answered on the receiving side.

Abstract: Two thiomarinol derivatives, which have antibacterial and anti-mycoplasmal properties, are obtainable from microorganisms of the genus Alteromonas and are named "thiomarinol B" and "thiomarinol C". Thiomarinol B can also be prepared by the oxidation of thiomarinol.

Abstract: A tire structure includes bag-like members capable of expansion and contraction and which are buried in anti-slip grooves in the tire surface, and an air supply coupled to the bag-like members for supplying air to inflate the bag-like members to cause them to expand and project outwardly of the tire surface. The air supply may include stems coupled to an air source in the wheel part of the tire structure. Normally, the tire structure can be run as a usual tire. When running on a frozen road or the like, the tire structure permits functions and effects like a tire with a chain coupled thereto to be obtained by a simple operation to inflate and expand the bag-like members to cause them to project outwardly of the tire surface, and without need of any cumbersome operation of mounting a chain to the tire.

Abstract: A sample solution is dripped on an injection region with a pipette. The sample solution immediately spreads in a reaction region by a capillary phenomenon. The sample solution is left for a predetermined period of time to bind a biological associated material in the sample solution with a specific affinity material bound on the inner surface of the reaction region. After the reaction, the outer surface portion of a support member is pushed against a reaction vessel main body to deform the support member, thereby bringing the sample solution into contact with a water absorbent member at a removal region. The sample solution is absorbed by the water absorbent member and is removed from the reaction region. A cleaning solution is dripped on the injection region in an appropriate amount to perform B/F separation and is allowed to spread in the reaction region. The cleaning solution is absorbed and removed by the water absorbent member. The biological associated material bound to the reaction region is assayed.

The ignition coil, which for this purpose is provided with a bore, may be slipped onto the bolt and a fastener provided with a resiliently expansible locking member may thereafter be slipped onto the bolt.

Abstract: There are disclosed a process for producing methyl formate by dehydrogenating methanol in liquid phase in the presence of a solid catalyst and a process according thereto wherein a gas (N.sub.2, H.sub.2, CO, etc.) is continuously blown into the liquid phase from outside, and the gas along with the reaction product are continuously withdrawn outside the reaction system from the gaseous phase directly or through a cooler. By virtue of the liquid-phase reaction in the above process, as compared with the conventional gaseous phase reaction, the reaction temperature can be lowered, the reaction gas rich in the objective methyl formate rather than methanol is obtained by continuously withdrawing the resultant methyl formate outside the reaction system and accordingly, a single pass yield higher than that at the thermodynamical equilibrium-value is assured, whereby energy saving is made possible.

Abstract: Direction of travel from a wave front in a pipeline is determined with two pressure sensors spaced relatively near to each other so that the site from which the wave front emanated is not located therebetween. For each sensor, a determination is made as to whether a detected signal has exceeded a negative or a positive threshold. In addition, the sensor outputs are subtracted from each other to determine which sensor detected the wave front first. Combining the resulting signals yields information on the nature of the wave front and its direction of travel.

Abstract: An invertor-controlled power unit includes a direct current power source circuit, an invertor circuit, and a pair of output lines. A waveform of voltage appearing between the output lines is detected. There is generated a target output waveform signal having a predetermined frequency. The target output waveform signal is converted into a control signal, which is then supplied to the invertor circuit. The invertor circuit effects switching control of an output from the direct current power source circuit in response to the control signal. There is detected an overvoltage state of the direct current power source circuit. The generation or supply of the control signal is inhibited while there is detected the overvoltage state of the direct current power source circuit. The control signal starts to be supplied again to the invertor circuit at a timing at which the detected waveform of the voltage between the output lines crosses a substantially zero volt level.
