Title: Excavation method of tunnel boring machine
Inventor: HASEGAWA ISAO
IPC: E21D9/10
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To avoid inconveniences in excavation resulting from differences of strength of a natural ground and effectively excavate the ground continuously. SOLUTION: When a procedure starts, a natural ground is actually excavated. In this time, the revolution number R and the excavation speed V are adjusted and the ground is excavated so that a torque and a thrust force acting on a cutter head are kept lower than a limit value. Then, measured values of respective sensors are input and the strength σ of the natural ground being actually excavated is estimated and whether the strength σ is in between strengths σ1 and σ2 preset in advance or not is judged. If the strength σ is not in between σ1 and σ2, the ground is excavated in a synchronous excavation mode in which two sets of main grippers and thrust jacks are simultaneously stretched and contracted.  When the strength σ is in between σ1 and σ2, the cutting head is advanced by making use of the reaction in the main gripper of one of sets. The other set of main gripper and thrust jack are contracted to prepare the excavating operation during the advancing process, and the ground is excavated in a continuous excavation mode repeating these motions alternately.

Title: Semiconductor device
Inventor: KIMURA KIMIYOSHI
IPC: H01L29/43
Filed: 1982-03-27
Abstract: PURPOSE:To perfectly prevent diffusion of metals into a Si substrate during thermal processing by forming the junction area in isolated manner between metal electrode and poly crystalline Si from the junction area of impurity layer. CONSTITUTION:An impurity layer 3 is formed on the one surface of Si substrate 1 with an oxide film 2 selective formed thereon used as the mask. Moreover, an oxide film 4 is formed, leaving a part of the layer 2 and a semiconductor layer, for example, a poly crystalline Si layer 5 is grown thereon. An impurity in the same conductivity type as the layer 3 is diffused into the layer 5, and thereafter the surface is thermally oxidized to have a low resistance. Thus, the layer 5 and layer 3 are electrically connected and simultaneously an oxide film 6 is formed. Then, a window is opened at the intermediate portion 6 of the film 5 being apart in lateral from the junction area between the layer 5 and layer 3, a metal electrode 7 is formed and a close contact with Si 5 is obtained. According to this structure, the junction area between the electrode 7 and Si 5 is isolated from the junction area of layer 2 and the electrode 7 and substrate 1 sandwiches an oxide film. Therefore, diffusion of metal into substrate 1 can be perfectly prevented resulting from the thermal processing.

Title: Color discriminating element
Inventor: KURITA MASAKATSU
IPC: G01J3/46
Filed: 1981-04-03
Abstract: PURPOSE:To improve space resolution, by differentiating the light receiving areas of a photoelectric transducing part, compensating the difference between light receiving sensitivities for three primary color light beams, and obtaining the optical currents having the values corresponding to the component ratio of the three primary color light beams in the light to be detected. CONSTITUTION:The light receiving areas of the light receiving elements 7r, 7b, and 7g of the light discriminating element 5' are different to each other. The light receiving area Sb of the light receiving element 7b for a blue color is set to be sufficiently larger than the light receiving areas Sg and Sr of the other elements 7g and 7r, and the area Sg is set to be larger than the Sr. Therefore the ratio of the areas Sb, Sg, and Sr are set so that the ratio is inversely proportional to the light receiving sensitivities to the three primary color light beams. The ratio of the optical current Ib, Ig, and Ir flowing the elements 7b, 7g, and 7r approximately corresponds to the ratio of the components of the three primary color light beams in the light to be detected.

Title: Laser driving device
Inventor: KIRII SUSUMU
IPC: G11B7/125
Filed: 1989-03-01
Abstract: PURPOSE:To control the output power of a laser diode in a simple circuit configuration by digitally storing a value corresponding to the output power of the laser diode. CONSTITUTION:A reproducing power control circuit 6 consists of a comparator 6a, an up/down counter 9, and a D/A converter 10, which converts the counted value of the up/down counter 9 into the analogue signal and outputs it to a reproducing power driving circuit 7. In such a case, the output power of the laser diode in servo byte parts 11a to 11d before data parts 12a to 12c is digitally stored. Consequently even when a voltage larger than the prescribed value is held, a time to restore the prescribed value is not consumed, and the held voltage does not fluctuate between the servo bytes 11a to 11d. Thus the output power of the laser diode can be controlled in the simple configuration.

Inversely, when the DC voltage of an H level is applied as the control signal through the resistor 11 to the terminal 8, the current is not made flow to the transistor 51 and the current is made flow only to the transistor 52. Thus, the output of a buffer amplifier 4 appears in the terminal 8 and also the signal is outputted through the capacitor 12.
