Abstract: DIESEL TRUCK ROAD SPEED CONTROL                 ABSTRACT OF THE DISCLOSURE           Effective supervision of the road speed of a diesel truck requires termination of the operation of the engine when the truck is operated at an excessive speed.  Utilizing to advantage what is already available, namely an engine shut-down control when the engine lubricating oil pressure is below a specified pressure, the device hereof provides the referred to road speed supervision in an effective manner and with minimum expense and complication.  Specifically, the within road speed control contemplates creating an "artificial" loss of lubricating oil pressure, i.e. one that is not due to an actual defect or malfunction of the lubricating oil circulating system,  but rather one that is responsive to the operation of the truck at an excessive speed. Said "artificial" loss of lubricating oil pressure is, of course, just as effective as an actual pressure loss in causing engine shut-off or slow-down, thereby providing effective road speed supervision for the diesel truck.

Abstract: ABSTRACT OF THE DISCLOSURE         A solar heat collector uses elongated, tubular, outer casings, in a fixed position with respect to the solar orbit, surrounding inner tubular sections, carrying heat-conductive fluid. The outer casings are highly transparent and the walls of the outer casings are of substantial thickness and of a high refractive index to admit solar heat energy and to focus it on or towards the inner tubular sections or tubes that are of highly conductive material and have dark, heat-absorbing surfaces.           One of the sides of the outer casings faces toward the sun. The other of the sides of the outer casings are coated with a highly reflective material to reflect any solar energy that by-passes the tubes, back to the inner tubes.           each of the casings is mounted in a substantially vertical plane, and the solar heat collector would normally con-sist of a plurality of such casings, or units, mounted side by side in a fixed plane approximately normal to the noonday, winter sun, or perpendicular to the sun's orbit.           The upper and lower ends of the tubes are connected to a system for storing or using the heat-conductive fluid after it is warmed by the solar energy.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention discloses a virtual machine system having a virtual storage function, wherein registers are provided for holding the heading and trailing addresses of the continuous area on the main storage assigned respectively for each of the plural operating systems. When access is performed to the main storage from the channel or sub-channel, one of the registers is selected. The heading address of the register selected is added to the main storage address sent from the channel or sub-channel.         The added main storage address is compared with the trailing address in the selected register and, if the former is smaller than the latter, the over head for supporting the virtual storage is reduced by making access to the main storage in accordance with the added main storage address.

Abstract: ABSTRACT OF THE DISCLOSURE:          In a method and apparatus for surveying for nodular targets of a grain size of 1 to 15 cm present on the sea floor, pulse waves in each of three frequency ranges of 3 to 4, 10 to 14 and 25 to 50 KHz are radiated onto the sea floor from a ship navigating on the sea.  The reflected sound waves of the three frequency pulse waves are received and the reflexibilities of the respective sound waves are measured from the reflected sound pressures and the reflexibilities are composed.  The population of the nodular targets is determined from the composed reflexibility and, as required, the grain size of the nodular targets can be determined from at least one of the ratio of the reflexibility of the sound waves of the frequency range of 3 to 4 KHz to the composed reflexibility and the ratio of the reflexibility of the sound waves of the frequency range of 3 to 4 KHz to the reflexibility of the sound waves of range of 25 to 50 KHz.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of food heating control is disclosed in which the heating time length (To) from a time point (t1) when the food temperature changing with the heating thereof reaches a predetermined set value (T1) to a time point (t2) when the vapor or gas liberated by heating of the food begins to increase the humidity or gas concentration is used as a basis for automatically determining a subsequent heating time length (tR).          In view of the fact that the time period (tR) for subsequent heating process is determined by the heating time from the time point when the food temperature reaches a predetermined set value to the time point when humidity or gas concentration begins to increase unlike in the prior art method in which the heating time from start of heating to the time point when humidity begins to increase is used to determine the subsequent heating time, the error in the heating time which otherwise might be caused by the variation in the initial food temperature is obviated, thus making it possible to determine the total heating time without being substantially affected by the food initial temperature.

Abstract: ABSTRACT OF THE DISCLOSURE A control system 54 for a doser type hydraulic actuator 56 is disclosed.  The doser actuator includes a pair of unequal area pistons 18, 20 on a common shaft 16 which are moved incrementally by injecting into or removing from a control pressure chamber metered quantities or doses of fluid.  The doses are metered by timed openings of solenoid valves 32, 34 connecting the control pressure chambered to a supply 44 or return 48 pressure sources.  The control system includes a base pulse width signal generator 106 which pulse modulates the solenoids as a function of the error between a requested position and an actual position.  The base pulse width is modified by a correc-tion means 108, 110, 112 when the error is within a predetermined band width.  The correcting means compensates for the variations of the actuator when its response is uncertain with respect to the base pulse width.
