Patent JP-S58170077-A (JP)
Title: Semiconductor photodetector
Inventor: KANEDA TAKAO
IPC: H01L31/109
Filed: 1982-03-31
Abstract: PURPOSE:To form a photodetector which has high reliability and high sensitivity necessary for a light communication by forming a planar structure that an FET and a monolithic photodiode formed at the outside of the FET region are formed in an isolation region. CONSTITUTION:A photodiode section is manufactured by forming a cadmium (Cd) implantation p type layer 8 on an n type InP layer 7. When infrared ray, for example, of 1.55mum as a light transmission signal is absorbed by a light absorbing layer in a photodiode having a band gap adapted to receive the infrared light 12 of 1.55mum, i.e., the p type layer 8 and an n type InGaAs layer 2, electron-hole pairs are immediately generated, and a voltage is applied in advance in reverse direction. Accordingly, holes H are moved toward the negative electrode direction at upper side. Thus, a voltage is generated in the photodiode. Since the gate G in a J-FET and the photodiode are connected, the output voltage of the J-FET can be controlled by the voltage produced by the light transmission signal.

Title: Heater tempperature-controlling safety device
Inventor: USHIO YUKIHIDE
IPC: H05B3/00
Filed: 1991-02-26
Abstract: PURPOSE:To provide a heater temperature-controlling safety device whose cost and area reductions are achieved and which is stably and surely operated regardless of aging deterioration and environmental changes. CONSTITUTION:When a heater 1 is cooled below a predetermined temperature, a CPU 12 starts transmission of electricity to the heater and performs electricity transmission using two electricity transmission patterns of different duties. The CPU 12 further measures and compares the time required for the predetermined temperature to be reached in one electricity transmission pattern with in the other pattern, and when the time required in the case of the electricity transmission pattern with a smaller duty is shorter than in the case of the pattern with a larger duty, the CPU 12 judges this to be abnormal and turns off a relay so as to cut off energization to the heater 1.

Abstract: PURPOSE: To easily and inexpensively provide the well-designed hanger with which clothing can be surely prevented from being slipped down by integrating a slip stopper for preventing clothing from being slipped at the upper part of the main body of the hanger for hanging clothing by molding it in two colors. CONSTITUTION: In this hanger, a slip stopper 2 for preventing clothing from being slipped is integrally formed at the upper part of a main body 1 of the hanger for hanging clothing by being molded. On the other hand, the cross section of the main body 1 of the hanger is inversely U-shaped by using a rigid synthetic resin, parts 10 corresponding to the shoulder parts of clothing are made round, and a metallic hook 3 is projected at the center of the upper part. Then, the slip stopper 2 is molded in two colors by using a soft synthetic resin or synthetic rubber and integrated with the main body 1 of the hanger. At this time, the slip stopper 2 is embedded inside a recessed groove 11 formed at the upper part of the main body 1 of the hanger in the state of exposing its surface.  Thus, the well-designed hanger, with which clothing can be prevented from being slipped down, can be easily and inexpensively obtained.

Title: Heat exchange fan duct for cooling tower and the like
Inventor: NAKAI HIROSHI
IPC: F28F25/12
Filed: 1994-03-24
Abstract: PURPOSE:To provide a fan duct having a longer service life, in which a fan is kept from causing duct resonance by designing the duct in such a manner that its natural frequency is different from the frequency of vibrations produced by the fan. CONSTITUTION:A fan duct 3 is arranged on an upper face of a fan deck plate 6, so as to envelope a fan 5 set at an upper section of a heat exchanger 4. In this case, a hollow state enforcement rib as an accommodating section 2 is set with projection with a predetermined space toward longitudinal and lateral direction so as to be in mutual communication. By the way, if a fan 5 is made to rotate with a predetermined rotation number, an agitation frequency generated by a wind pressure coincides with a dominant natural frequency of a fan duct 3, there is a case wherein a resonance phenomenon is generated. In this case, a filler material of sand and the like is inserted and mounted in an inside section of an accommodating section 2. By this, a weight of the fan duct body 1 is increased, and this natural frequency is made to execute a fluctuation. Accordingly, a generation of a resonance phenomenon can be evaded.

Abstract: PURPOSE:To intend to keep a predetermined inertial force of a fuel rod by providing a spring to support the fuel rod at a part of a strap which forms a grid space, by fixing one end of the spring to the strap and by engaging the other end with an engaging part. CONSTITUTION:After fixing an upper end of a spring 3 to a notch part which is an upper part of a strap 1, a lower end of the spring 3 is positioned at an outer surface of an engaging part 1c of the strap 1. Then, a jig 11 is pushed upwardly to press the lower end of the spring 3 by an end tip of an pressing part 11b of the jig 11. After that, with a slanting part 3b formed at the lower end of the spring 3, a horizontal component of force works to the slanting part 3b and the lower part of the spring 3 is made to get an inertial force to be moved towards the notch part side of the engaging part 1c. At the same time, the spring 3 is pressed and bent upwardly to be moved to an inner side of the notch part by a returning force of the spring 3. Consequently, the lower end part of the spring 3 is pressed into the notch part of the engaging part 1c, by its own returning force.
