Title: Manufacture of high density silicon nitride
Inventor: MATSUO YUKITOSHI
IPC: H01L21/318
Filed: 1981-05-11
Abstract: PURPOSE: To obtain a high density silicon nitride film with superior spalling resistance by using carbon having a restricted range of specific gravity and low air permeability as a substrate and vapor-depositing silicon nitride from a gaseous phase.  
     CONSTITUTION: Carbon having 1.30W1.60g/cc specific gravity according to an n-butyl alcohol method and ≤10 -6 cm 2 /sec air permeability is used as a substrate, and silicon nitride is vapor-deposited from a gaseous phase by a CVD method. The resulting silicon nitride film is homogeneous, the thermal strain is uniformly dispersed during cooling after the deposition, and the film bonds very firmly to the substrate. Even after removing the carbon substrate by oxidation, the film does not cause cracking and shows high spalling resistance. When the specific gravity of the carbon substrate is not within said range, the spalling resistance of the deposited film is deteriorated. When the air permeability exceeds said restriction, the number of the surface open pores of the substrate is increased, and a thermal strain causing crakcing remains in the deposited film.

Title: Automatic adjusting valve
Inventor: YAMADA SHINICHI
IPC: F16K17/10
Filed: 1981-05-13
Abstract: PURPOSE:To have rapid and accurate pressure control by incorporating an automatic adjusting valve to control the pressure in the pressure circulating passage always constant, where a by-pass is formed in accordance with the piston response to change of the pressure. CONSTITUTION:In normal pressure condition, the pressure of helium gas, P flowing through the low-pressure side circulating passage 2b and divergent passage 5b is balanced with the combination force of the atmospheric pressure with the elastic force of an elastic member 10 to press a piston 9 upward, so that the piston 9 and piston rod 14 do not act. When a pressure P1 on the low pressure  side exceeding a certain set value acts on the piston 9, it is depressed against  the elastic force of the elastic member 10 and, at the same time, the piston rod  14 is depressed. This fall of piston rod 14 will cause formation of No.1 by-pass  17 which puts No.1 communication hole 19 in the piston rod 14 in communication with the pressure P2 through a ring-shaped passage 26a in a pilot piece 23,  and then the pressure on the high pressure side P2, is discharged into a slide  hole 28a and acts on the disc head 31.

Title: Digital phase locked loop circuit
Inventor: TANAKA KOICHI
IPC: H03L7/099
Filed: 1986-03-31
Abstract: PURPOSE:To improve the resolution of phase change by using an m-phase basic clock having a frequency being N-time of the frequency of a synchronizing signal desired to be obtained so as to make the phase change of the synchronizing signal as 2pi/(Nxm) radians. CONSTITUTION:When the phase of the synchronizing signal is retarded from the phase of input signal, an up signal is generated, and the operating sequence of counters 20,21,22 is changed in the order of counter 20   22   21   20 while the phase of the basic clock input is circulated in a loop in a progressing direction, and the phase of a synchronizing signal is advanced by l/3 clock each at each change. When the phase of synchronizing signal is delayed conversely, a down signal is generated and the phase of synchronizing signal is retarded by 1/3 clock each at each changh. Thus, when a phase difference between the synchronizing signal and the input signal is caused, the time of one period of the synchronizing signal is increased/ decreased in the unit of 2pi/(4X3) radians, that is, in the unit of 2pi/Nxm radians for the m-phase.

Title: Method for monitoring abnormality of concrete
Inventor: OGAWA HIRONORI
IPC: E04G23/02
Filed: 1994-04-11
Abstract: PURPOSE:To automatically detect the generation of abnormality such as cracks of concrete, etc., by burying a conductor in the concrete in a place to be monitored for its abnormality and measuring the electrical characteristic of the conductor. CONSTITUTION:When abnormalities such as rupture of concrete, etc., are generated at an abnormality-monitoring point A, a resistance wire 3 is, for example, elongated in its lengthwise direction and the resistance value R1 becomes larger. The larger the resistance value R1 is, the smaller the voltage Es is. In this case, the status is judged to be abnormal by #2 of a processing circuit 7 because of reference voltage Er > output voltage Es, and #4 instructs an alarm device 9 to issue an alarm. Thus, while a current is allowed flow in the wire 3, the change of current is replaced with the change of the voltage Es and the external force working onto the wire 3 is monitored so as to detect the generation of abnormal state. Further, a large abnormality of the abnormality monitoring point of the concrete can be predicted by detecting minor abnormality thereof.
