Patent JP-S57133740-A (JP)
Title: Control method for transmission system
Inventor: MOROTOMI HISASHI
IPC: H04Q9/00
Filed: 1981-02-12
Abstract: PURPOSE:To keep the operation of stations sound, by skipping polling to slave stations in system-down. CONSTITUTION:A master station inquires the presence of system-down to a plurality of slave stations. A slave station receiving the sequence inquring the presence of system-down makes response to the master station, but the slave station in system-down does not give any response. The detection of system-down like this is made in a specified period. The master station avoids polling to the down station to prevent useless time. When the master station detects the recovery of the down slave station, polling is made again.

Abstract: PURPOSE:To obtain a semiconductor laser with stable characteristics by a method wherein a current constriction layer is provided in the semiconductor laser and the thickness of a cladding layer is thin enough for an oscillated laser beam to be absorbed by the current constriction layer. CONSTITUTION:After the lamination upto a current constriction layer 103 is completed, the current constriction layer 103 is etched to form a stripe shape window through which 1st cladding layer 102 is exposed.

Title: Liquid drop jet recording method
Inventor: SHIRATO YOSHIAKI
IPC: B41J2/05
Filed: 1979-02-22
Abstract: PURPOSE:To make it possible to carry out high speed recording at good energy efficiency by supplying a signal formed by an electromagnetic wave energy to a recording liquid within an operating chamber as a pulse of a specific value. CONSTITUTION:An ink 2 is introduced and placed in a glassfiber tube 1 in a direction shown by arrow, and an electromagnetic wave energy pulse 4 as a signal is applied instantaneously to a part close to as discharge orifice 3. The signal generated by the electromagnetic wave energy is supplied as such a pulse that the half- value width of the peak energy becomes less than 100mu/sec. Then, the electromagnetic energy which has permeated through the glassfiber tube 1 is absorbed to the ink 2, which is heated locally and is vaporized instantaneously to form bubbles 5. By the variation of the state of the ink 2, ink drops 7 are exhausted through the orifice 3 and adhere to the surface to be recorded, thus recording being carried out. Shortening of the pulse width r entails energy sparing.

Title: Detector for semiconductor device
Inventor: TAKANO HIROMI
IPC: G01R1/073
Filed: 1980-02-20
Abstract: PURPOSE:To make the judgement of a tester correspond to that of a probing device as to whether there exists an element or not by a method wherein a probe on a  probing card is used to detect whether it has been contacted by an IC and send information concerning the detection to a tester simultaneously with a signal indicating that it has started measuring. CONSTITUTION:When a detecting probe 5 comes in contact with a semiconductor substrate 2, the probe is separated from a detecting probe 4. Therefore, the voltage in a detection circuit 19 rises to synthesize the information as to the rise in voltage and the output of a circuit 21 for generating a signal informing the commencement of measurement, together in an output circuit 20 so that the information is output. Since a detecting probe 6 does not contact a substrate 2 but a detecting probe 7, the voltage in the detecting circuit 19 does not change, allowing no transmission of the output signal. The output signal 20 opens a relay 16 and maintains the detecting signal, while the signal in the circuit 21 for generating a signal informing the commencement of measurement and the signal 20 are transmitted simultaneously. As a result, the counting of the tester can be made conformable with that of the probe, making it possible to obtain a highly reliable substrate tester.

Title: Screw for single screw extruder
Inventor: KOBAYASHI NOBUHISA
IPC: B29C48/395
Filed: 1980-02-19
Abstract: PURPOSE:To permit the screw of a single screw extruder to be free from a deflective pressure and prevent production of dragging by providing dragging preventing notches at several portions in the screw flight part where the internal resin pressure  has a peak. CONSTITUTION:Over several channels, notches 7 are provided at several portions in the screw flight 3 portion where 3 peak pressure is produced. Thereby, polymer flows from a channel 6a on the downstream side into a channel 6b on the upstream side through the notches 7. Accordingly, the pressure difference is reduced, and the peak value of the internal resin pressure and the side force decrease as well as the screw 2 is wrapped in the polymer passing through the notches 7 and so held that no deflective pressure is applied to the screw 2.

Title: Cooling equipment for electronic apparatus
Inventor: SUZUKI YASUSHI
IPC: H01L23/467
Filed: 1994-02-17
Abstract: PURPOSE:To keep constant the temperature of a d.c. power supply and a load apparatus by controlling the speed of cooling fan revolution based on the output voltage of an integrating circuit, which receives control signals for the control of transistor operation from the voltage control circuit in the d.c. power supply and integrates the signals, and the input voltage of the d.c. power supply. CONSTITUTION:The calorific values of a d.c. power supply 10 and a load apparatus are proportional to output current, and calorific value is proportional to a product of duty factor D and input voltage Ei. The magnitude of duty factor D is obtained by integrating PWM signals (switching control signals), which control the on and off of a transistor 3, by means of an integrating circuit 21. Therefore, the speed of the revolution of a cooling fan 14 is controlled according to values obtained by multiplying values from the integration of the PWM signals by values of input voltage Ei. Thus the speed of cooling fan 14 revolution is controlled at the same time as load current fluctuates. This makes it possible to increase the cooling capability before the temperature of the d.c. power supply 10 or the load apparatus 11 rises.
