Title: Method for forming track guide groove on optical disc medium
Inventor: YAMAZAKI HIRONORI
IPC: G11B7/26
Filed: 1983-03-16
Abstract: PURPOSE:To improve the SN ratio of an optical medium and reduce the error rate by heating a reflective film with irradiation of a laser light through a transparent substrate to form track guide grooves on the surface layer of the substrate. CONSTITUTION:An optical disc medium is irradiated with a laser light 4 through a condenser lens 5 provided on the back of a substrate 1 while the transparent substrate 1 is rotated. The condensed laser light 4 is transmitted through the transparent substrate 1 and strikes the rear side of a reflective film 2 to heat this irradiated part locally. The surface layer of the substrate 1 brought into contact with the reflective film 2 is heated by heat conduction of heating of the reflective film 2 and is expanded into a projection to form a track guide groove 3. Thus, the SN ratio of the optical disc is improved, and the error rate is reduced.

Title: Lead electrode containing aggregate material for electrolytic purification of zinc
Inventor: NOERU DORUURU
IPC: C25C7/02
Filed: 1982-03-17
Abstract: The anodes for the electrolytic production of zinc from acid aqueous solutions of sulphate comprise a skin portion formed by conventional anode metal, lead containing from 0.25 to 1.0% silver, and a stiffening reinforcing member of titanium or zirconium. The reduction in thickness of the anodes, which is made possible by the provision of the reinforcing member, results in a substantial saving in the amount of silver-bearing lead which is immobilized, and a substantial reduction in the unit weight of the anodes. The resistance of the lead to anodic corrosion in a sulphuric acid medium is maintained and the resistance to corrosion by passivation of the reinforcing member permits the reinforcing member to be accidentally exposed, without disadvantage. To produce the anodes, the reinforcing members are clad with lead at a temperature of more than 100 DEG  by rolling sheets of lead, by casting in a mould or by spraying on molten lead.

Title: Mobile communication system
Inventor: KITO EIJI
IPC: H04B7/26
Filed: 1990-02-22
Abstract: PURPOSE:To suppress energy consumption and to improve the convenience of a user by sending out the time slot of an incoming signal in a radio control signal while changing the time slot to a period set in advance for a mobile station when an absence response signal can not be received from a radio base station for prescribed time. CONSTITUTION:When a mobile station 3 is set at a position where radio waves can not be arrived, the response signal is not sent out from the mobile station 3. Therefore, the CPU 25 of the radio base station 2 judges whether the fixed time set in advance is lapsed after the transmission of the incoming signal or not. After the lapse of the fixed time, the CPU 25 judges whether the incoming signals of fixed number of times are sent out or not. When the signals are not sent out the fixed number of times, the CPU 25 changes the time slot of the incoming signal to the time slot of incoming call (i) determined in advance for the mobile station 3 and repeats the transmission of the incoming signal. When the response signal can not be received even after sending out the incoming signal of the fixed number of times, an incoming disabled signal is sent out to a fixed telephone network 1. Then, the fixed telephone network 1 informs it to a caller that incoming call can not be executed.

IPC: B60L7/04
Filed: 1979-04-09
Abstract: PURPOSE: To prevent overvoltage and overcurrent by switching the first and second current for setting the dynamic brake current each corresponding to the first and second preset speed.  
     CONSTITUTION: When the vehicle speed exceeds the first preset speed, the first set speed signal corresponding to the first preset speed from the first speed pattern generator 18 is compared with the vehicle speed detected by means of a comparator 19. Thus, the output relay 21 provided through the speed detector 20 in noway excited. As the drop of the vehicle speed actuates the output relay 21, the current pattern change-over relay is excited and the first set current signal is cut at the contact 24a of the change-over relay 24, so that the contact 24b is closed to allow the second set current signal to be inputted into a comparator 14. The second set signal is outputted from the second generator 25 to switch the set current signal whereby a large braking force is obtained corresponding to the set current at the low speed range. Accordingly, overvoltage and overcurrent can be prevented.
