Title: Valve device of sealed compressor
Inventor: KITA ICHIRO
IPC: F04B39/10
Filed: 1989-12-13
Abstract: PURPOSE:To decrease micro-vibration of a valve device during the opening or closing of it by forming a delivery valve with its length from a base portion to an end unequal on the right and left sides of an axis, and making different the frequency modes of the delivery valve on the right and left sides so as to eliminate frequency modes which are hard to be damped as a whole. CONSTITUTION:When a piston 1 reciprocates inside a cylinder 3 compressed gas is allowed to pass through the delivery hole 5 of a valve plate 4 to push up the delivery valve 14 of a delivery valve reed 9. As a result, the delivery valve 14 is opened while being regulated by a delivery valve stopper 15, and the gas is delivered to the delivery chamber 16 of a cylinder head 7. In this case, the delivery valve 14 has its longitudinal side 20 opened first with a base portion 19 as a point of support and then the opposite side 21 is raised. The length of the delivery valve 14 from the base portion 19 to an end is set in such a manner that lengths are unequal on the right and left sides of an axis 18. The frequency mode of the delivery valve 14 on the longitudinal side 20 is therefore made different from that on the opposite side 21 so as to properly decrease predetermined characteristic frequency modes which are hard to be damped.

Title: Loop filter circuit of carrier wave reproducing circuit
Inventor: OKADA KAZUO
IPC: H04L27/227
Filed: 1990-11-27
Abstract: PURPOSE:To constitute the circuit so that the PLL can be locked surely even if a value of a complete integral part of a loop filter circuit is large by inserting an adder for adding a stationary prescribed value, into a pre-stage of a loop filter, and using that which has no overprotect as a latch circuit. CONSTITUTION:Phase difference data psi is sent to an adder 18 and a small prescribed value set in advance is added, so that information of a phase difference does not become '0' even in a state that a PLL is locked completely. A complete integral part 17 has no overprotect, therefore, when an integral value becomes larger gradually by a loop of several times, and a value of the complete integral part 17 overflows, it becomes a small value again. When this integral value becomes small it is reflected on an output and leading-in of the PLL is executed. In such a way, when a power source is turned on, etc., even if the value of the complete integral part is any value, the PLL comes to be locked soon, and an operation of a loop filter is stabilized.

Filed: 1990-11-26
Abstract: PURPOSE:To improve the uniformity in thickness of a thin film formed by making a plate for controlling the heat transmitted to a substrate larger than the substrate and increasing the roughness of the surface of the plate opposed to the substrate except is center. CONSTITUTION:A soaking plate for controlling the heat transmitted to a substrate from a heater is provided close to the substrate. The soaking plate is made larger than the substrate. The roughness of the surface of the soaking plate opposed to the substrate except its center is made greater than that of the center, and the IR emissivity of the center of the soaking plate is made smaller than that of the part except the center.

Title: Projection device
Inventor: TERASAWA CHIAKI
IPC: G02B13/16
Filed: 1990-11-26
Abstract: PURPOSE:To obtain a projected image with favorable optical performance over the whole of a screen by way of effectively correcting astigmatism by forming a back reflecting mirror of a convex refractive surface with a convex surface facing the side of a screen surface and a convex reflecting mirror, and satisfying a specified formula. CONSTITUTION:This device enlarges and projects an image projected on a fluorescent screen 4b of a Braun tube 4a on a screen 1 after refractively reflecting the image on a back reflecting mirror 2 by a projection lens 3. When a negative refractive power phiR of the back reflecting mirror exceeds the lower limit value of a condition formula I and comes to be too strong, it comes to be difficult to correct astigmatism. Subsequently, when the negative refractive power phiR of the back reflecting mirror exceeds the upper limit value and comes to be too weak, an optical action as a convex mirror comes to be weak, and it comes to be difficult to obtain a specific projection magnification. The astigmatism is favorably corrected by properly setting it by way of using a radius of curvature R when a radius of curvature (r) of a convex reflecting mirror on the back of the back reflecting mirror is converted into a surface reflecting mirror by a condition formula II. In this way, it is possible to extremely minimize the astigmatism by way of using the aforementioned back reflecting mirror.
