Title: Composite crucible, its producing method and regenerating method
Inventor: TSUJI YOSHIYUKI
IPC: C03B23/00
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To obtain a composite crucible which is excellent in the material strength, eliminates a fear of the deformation at a high temp. and which can achieve a high crystallization rate of single crystal by making the inner layer of quartz glass and the outer layer of a carbonaceous material in the composite crucible for pulling silicon single crystal and integrating the inner and outer layers into one body. SOLUTION: The outer layer 10 of a crucible is made of a carbonaceous material and the inner layer 20 is made of quartz glass. The carbonaceous material of the outer layer 10 and the quartz glass of the inner layer are tightly adhered into one body to form a composite material. The carbonaceous material to form the outer layer 10 is a solid carbon material such as graphite and carbon fiber. Since the carbonaceous material has excellent heat resistance and high material strength, the composite crucible having excellent dimensional stability at a high temp. is obtained by forming the outer layer from the carbonaceous material. The outer layer is preferably formed from the carbon fiber having 0.1 to 1.0 mm average roughness and a 0.2 to 5 mm average interval of the roughness of the face brought in contact with the quartz glass of the inner layer 20.

Title: Electromagnetic type power boosting device
Inventor: SHIMIZU YASUO
IPC: B62D5/04
Filed: 1984-08-16
Abstract: PURPOSE:To prevent hunting in a low torque operating range, by defining the dead zone of signals which determine the energizing amount of current for an armature in an electrically driven PS device, wider than the dead zone of signals which determine the energizing direction of the armature current. CONSTITUTION:When a torque is applied externally to an input shaft 1 so that the torque is detected by a torque detecting section 13 between input and output shafts 1, 4, an armature current is fed to a winding 25 under operation of a control circuit. Accordingly, a motor 20 is driven so that a rotor 26 rotates in the same direction as that of the input shaft 1. The armature current which is fed to an armature 20 from the control circuit is proportional to a voltage applied to an armature drive circuit. However, since the dead zone of the input voltage is made wider than the dead zone of the voltage which controls the energizing direction, the armature current may be stably fed so that a smooth steering operation may be effected.

IPC: B60R22/40
Filed: 1990-06-28
Abstract: PURPOSE:To prevent generation of abnormal sounds by making the bore of at least one part of the inner hole of a bush made from a synthetic resin smaller than that of the support hole of a turning movement arm, which bush is interposed between the inner peripheral face of the support hole of the turning movement arm and the outer peripheral face of a shaft.

Title: Exchange having camp-on guide function
Inventor: SATO KATSUSHIGE
IPC: H04M3/533
Filed: 1989-07-03
Abstract: PURPOSE:To prevent confusion due to calls by allowing a reply party to listen to guide in voice when an extension telephone set with camp-on set thereto is called back due to 'idle state' of a set telephone set. CONSTITUTION:When an extension telephone set B in busy state sets the camp-on to the extension telephone set B from an extension telephone set A, the information is transferred to a central processing unit CPU and stored in a memory. When the state of the extension telephone set B changes from 'busy state' into 'idle state', the CPU identifies it that the camp-on is set to the extension telephone set B. When the extension telephone set A is called and a reply comes, the CPU connects the extension telephone set A to a talkie trunk VRT to send a message. Then the CPU sends a call signal to the extension telephone set B and a call tone to the extension telephone set A to apply talking connection. Since voice guidance is implemented by connecting itself to the telephone set B, the callback call is confirmed and confusion due to calls is prevented.
