Title: Testing method of hydrogen induced cracking
Inventor: NAKADE HIROSHI
IPC: G01N17/00
Filed: 1983-03-25
Abstract: PURPOSE:To inspect hydrogen induced cracking accurately by dipping a polygonal cylinder which consists of plural test-pieces in combination and has a gas vent for the inside of a hollow at its one terminal in the test liquid in a test tank, and saturating the liquid with gaseous H2S and allowing H to permeate internal surfaces of the polygonal cylinder. CONSTITUTION:When cracking caused by H produced by the reaction between Fe and H2S on the surface of a steel material for a transportation pipe for petroleum, natural gas, etc., in a sulfide containing atmosphere is tested, a polygonal body, e.g. tetragon body 15 is formed by combining plural test-pieces ltogether and joining them airtightly with an adhesive 18 such as silicone rubber. A hole 16 is formed in one end surface of this body 15 and a gas vent tube 13 is connected thereto. This body 15 is put in the test tank 10 and dipped in test liquid 11 such as artificial sea water; and gaseous H2S is sent from a supply pipe 12 to saturate the liquid 11 by dissolving. The body 15 is taken out a specific time later and the hydrogen induced cracking state of each test-piece lis observed. Thus, an accurate test result is obtained by an almost actual test.

Title: Phase locked loop transmitter-receiver
Inventor: SUMIYA HIROYASU
IPC: H04L7/033
Filed: 1984-03-16
Abstract: PURPOSE:To attain stable operation even when the speed of an input signal is increased by setting a self-running frequency of a read clock to a stable point with a phase locked loop including an FF when interruption of an input and out of synchronism are detected. CONSTITUTION:The phase locked loop (PLL) is formed by a phase comparator section 28 using FF41, 42, a differential amplifier 29, an LPF30, a voltage controlled oscillator 31 and a read clock generator 27. When the input is interrupted, a detection section 63 detects it and if the synchronism is unlocked, an output of a frame synchronization pattern comparison section 62 detects (65) out of synchronism information. When the information representing interruption of input or out of synchronism is inputted to an OR circuit 64, an OR circuit 64 inputs an L level to an S terminal of the FF42. An output at a terminal Q of the FF42 goes to H, an exclusive OR circuit 43 gives an output and the frequency of the voltage controlled oscillator 31 is set based thereupon by using a reference voltage 35. Thus, in case of the interruption of input or out of synchronism the self-running frequency is set to one stable point so as to attain stable operation.

Title: Semiconductor device
Inventor: HONJO MASAO
IPC: H01L29/78
Filed: 1987-03-06
Abstract: PURPOSE:To obtain a MOSFET having the so-called self-alignment structure requiring no positioning accuracy and excellent frequency characteristics by insulating adjacent source region and drain region by an insulating film. CONSTITUTION:A reverse conductivity type source-drain region 2 is formed to one conductivity type substrate 1, an insulating film 4 protruding until a gate insulating region reaches at least one conductivity type region is shaped, and adjacent source region 3 and drain region 2 are insulated by the insulating film 4. That is, since the gate insulating film 4 is formed into the substrate 1 surrounded by the source region-drain region 3, 2, the dimensional machining of the insulating gate region can be executed at a time. Consequently, since accuracy is improved and insulation adjacent to the source-drain regions 3, 2 is conducted simultaneously, the gate length of a channel region is not altered due to the concentration change of the source-drain regions 3, 2. Accordingly, since positioning with a gate electrode 5 is unnecessitated, gate length is not dispersed due to positional displacement.

Filed: 1986-03-10
Abstract: PURPOSE:To provide an ohmic electrode having excellent heat resistance by composing a source electrode and a drain electrode of an aluminum material and composing a gate electrode of an Au material. CONSTITUTION:A p-type 3C-SiC single crystal film 2 is obtained on a p-type silicon substrate 1, and a non-doped n-type 3C-SiC single crystal layer 3 is then epitaxially grown. Then, after the surface of the layer 3 is sequentially etched with 5%-HF, 20%-K2CO3, HCl, 5%-HF, aluminum is deposited in vacuum to form a source electrode 4 and a drain electrode 5, Au is further deposited in vacuum to form a gate electrode 6. A separating region 7 is eventually formed by etching as an MESFET. Thus, a preferably ohmic contact is obtained without annealing by high temperature treating to eliminate the damage of the gate electrode.

Title: Jam detecter for fixing device
Inventor: SHIMAZAKI SHIGERU
IPC: G03G15/20
Filed: 1981-04-09
Abstract: PURPOSE:To achieve quick jam detection, by providing a non-contact thermal type infrared ray temperature sensor in a process step downstream of a peeling means and giving a jam detecting signal if the sensor output fluctuates a prescribed fluctuation band or more. CONSTITUTION:If a toner image support 6 is not peeled off with a peeling nail 4, the progressing direction ridge of the support 6 reaches the front of a non- contact temperature sensor 5, the reduction in the radiation of infrared rays from a heating roll 7 with the toner image support 6 is immediately detected with the sensor 5 and transmitted to a comparison circuit 12. Since an output signal from a temporary storage circuit 9 has a higher value before the reduction in the amount of radiation of infrared rays, the difference between the detected signal and the stored signal is detected at the comparison circuit 12, and the power supply of a heating device 14 is interrupted with the operation of a control circuit 13. Since this temperature sensor 5 has high sensitivity and response, the interruption of the power supply can quickly be made. Thus, quick jam detection can be made with the constitution.
