The bottom edge of the gel assembly rests on the flanges over the face of the integral bottom support member.

Abstract: A seat belt device for fastening a passenger seated on a seat comprises a shoulder belt carried by a seat back. A support strap is fixed at one end to the seat back and extends rearwardly. An anchor member is mounted on a body member of the vehicle rearward of the seat back for carrying the support strap. A retractor is mounted on a body member for winding up and retracting the support strap. A lock mechanism is provided in the retractor for preventing the support means from being drawn out from the retractor when a horizontal acceleration acting on the retractor is greater than a predetermined value. The seat belt device is reliable in case of an emergency and provides improved visuality.

Abstract: The concentration of molecular fluorine in a mixed gas such as an excimer laser gas can be determined easily, quickly and accurately by passing the mixed gas through a column packed with an alkali metal or alkaline earth metal compound which has no halogen atom and reacts with fluorine to form a solid fluoride together with molecular oxygen and/or carbon dioxide and measuring the concentration of oxygen or carbon dioxide in the fluorine-free gas flowed out of the packed column. If the mixed gas initially contains molecular oxygen or carbon dioxide, its concentration is measured separately after fixing fluorine in another column packed with an element which forms a fluoride. This analyzing method can be used in a feedback control system for controlling the concentration of fluorine in an excimer laser gas during operation of the laser to thereby stabilize the laser output power.

Abstract: A transit system is disclosed having a guideway, with the primary of a linear induction motor located at spaced intervals therealong. A train of vehicles is positioned to travel along the guideway and includes the secondary of the linear induction motor. The secondary extends along and between the vehicles in spaced relation with respect to the primary so as to encounter a magnetic field emanating from the primary to cause a thrust to be generated in the secondary. The secondary thereby provides an even distribution of the thrust along the frame, while reducing the loss of power when the train encounters corners and hills.

Abstract: An automatic speed control system for a vehicle includes a throttle control for controlling a throttle valve opening based on a deviation between a target speed and an actual speed of the vehicle so as to accomplish the target speed. A down-shift device for making a down-shift operation in an automatic transmission, a steady judging device for judging a steady condition of the actual speed after the down-shift operation, and an up-shift device for making an up-shift operation in the automatic transmission, when a reduction of the throttle valve opening more than a predetermined value is detected, after the actual speed is judged to be in the steady condition, are provided. A proper speed control can be provided when the vehicle runs uphill, regardless of the length and/or gradient of the uphill path.

Abstract: A method for simultaneous collection of seismic data of shallow and deep targets, in which two seismic streamers are towed at different water depths (1 and 2 in FIG. 2), and only one acoustic source of seismic signals is used. The seismic data recorded by the different streamers are mixed in a subsequent processing step, seismic data being weighted before being mixed by a weight which is made dependent on the recorded two-way travel time for the respective streamers, so that data from one or several streamers located at the least water depth receive a weight which decreases with travel time, whereas data from a corresponding number of streamers of greater depths receive a weight which increases with travel time.

Abstract: An automatic baking apparatus for making food products in piece form from dough-like substances which apparatus has holding means adapted to be fixed to the top and bottom edges of a flexible sealable mixbag (100) containing dry ingredients and water. The baking apparatus has upper and lower drums (230,232) and means for moving the drums, and the mixbag has male protrusions (134, 134a) at the upper and lower edges so that the mixbag (100) can be attached respectively to the upper and lower drums (230, 232). The holding means on the upper and lower drums is in the form of a female groove (234, 234a) commensurate in shape with the male protrusions (134, 134a) on the mixbag so that the mixbag male protrusions can be detachably interlocked with the female grooves on the drums. In this way the mixbag is attached to the drums for a kneading process in the baking apparatus and after the kneading process is completed, the mixbag is rolled up onto the lower drum (232).
