Title: Tripper position sensor for ore storage tank
Inventor: YAMASHITA NOBORU
IPC: B65G47/95
Filed: 1979-09-07
Abstract: PURPOSE: To arrange so that an accurate sensing may be realized economically, by providing near-by switch on the tripper body and near-by element on the tank and processing signal generated each time the near-by switch passes by the near-by element.  
     CONSTITUTION: Each output from near-by switches NLS 1 WNLS 6  is transmitted to sequence controller (SC) 4 . The SC 4 , receiving an operation command from the operation console 5 and the control computer 6, controls the electric motor for travelling tripper body 8 and feeder motor for driving feeder conveyor 21 through the intermediary of control center (CC). That is, if a certain tank is predetermined as an operation command and a counter built in SC 4  is preset, the SC 4  compares the preset value with the number of selected tanks, identifies the travelling direction and gives a travel command to CC 7 . During the travel, the number of tanks is sensed by adding/subtracting a signal from near-by switches NLS 1  and NSL 2  with SC 4 .

Title: Mobile telephone device
Inventor: KATO TATSUNORI
IPC: H04W12/00
Filed: 1988-05-11
Abstract: PURPOSE:To prevent the telephone number of a remote party station stored by an old user from being known to a new user by erasing all the contents of a storage circuit when the telephone number of its own station is changed. CONSTITUTION:The title device is provided with a control circuit 2 which decides that the telephone number of its own station was changed and erases all the contents of the storage circuit when the result of comparison and collation between the telephone number of its own station and the same stored in the storage circuit is discordance. In a case that a mobile telephone device is returned on account of the cancellation of a contract, etc., and is used by the new user, the control circuit 2 operates, and reads the telephone number of its own station from a telephone number setting circuit 4, and reads the telephone number of its own station from the storage circuit 1, and compares and collates the both. At that time, because both the telephone numbers do not coincide with each other since the old telephone number of its own station having been used formerly is stored in the storage circuit 1, the control circuit 2 erases all the contents of the storage circuit 1, and simultaneously, stores the new telephone number of its own station in the storage circuit 1. Thus, the telephone number of the remote party station stored by the old user is prevented from being known to others.

Title: Protecting device for exhaust pipe
Inventor: IMAI KANJI
IPC: H01J9/385
Filed: 1989-05-09
Abstract: PURPOSE:To protect an exhaust pipe by providing an armouring member for surrounding the exhaust pipe from the portion where a vacuum container abuts to the exhaust pipe to the end of the exhaust pipe, and packing an elastic adhesive inside the armouring member. CONSTITUTION:After an exhaust pipe 1 is sealed, an armouring member 3 for surrounding the exhaust pipe 1 from the portion where the exhaust pipe 1 abuts to a vacuum container 5 to the end of the exhaust pipe 1 is provided, and an elastic adhesive 4 is packed inside the armouring member 3. By the constitution, if an impact force is exerted on the exhaust pipe 1, the armouring member 3 receives the force, and then the impact force is dispersed by the adhesive 4. The impact force dispersed is absorbed by the portion where the armouring member 3 abuts to a glass container 5 and by elastic deformation of the adhesive 4. The impact force will therefore not be directly exerted on the exhaust pipe and so the exhaust pipe is protected.

Title: Light source unit
Inventor: KATO MASAYOSHI
IPC: F21Y101/00
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a light source unit realizing a long service life by simply and surely preventing a reflector or a light-transmitting plate from cracking. SOLUTION: In this light source unit U1, an opening in a reflector R is covered with a light-transmitting plate 20 by fixing the light-transmissive plate 20 to an opening peripheral part A of the reflector R, and thus a structure suitable for explosionproof is obtained. During light emission, not only the reflector R but the light-transmissive plate 20 is exposed to a high temperature, and air inside the reflector R maintains at an extremely high temperature. Then, the reflector R and the light-transmitting plate 20 are thermally expanded by the high temperature, and they sometimes crack due to the difference in their coefficients of thermal expansion.  To avoid such a situation, a part is cut out of the opening peripheral part A of the reflector R so that a light- transmissive plate housing part 21 is not formed over the entire circumference of the opening peripheral part A of the reflector R. By forming such a cutout in the opening peripheral part A, an escape for stresses due to thermal expansion can be creased, thus surely achieving the crack prevention of the reflector R and of the light-transmissive plate 20.

CONSTITUTION:A photoresist 32 of the prescribed thickness is spin-coated on the single side of a glass master disk 30 composing optical disk. Then a chrome film 34 of the prescribed thickness is formed on the resist 32. A laser beam is irradiated on the film 34 by an optical means of an argon laser 36 to evaporate the film 34 near the edge part of the disk 30. Then the resist 32 is exposed under the light with the film 34 used as a mask. Thus spiral groove pattern 38 is obtained. Then a photoresist 40 is coated again to the inner circumference area on the surface of the disk 30. A pattern is formed to the resist 40 with irradiation of an argon laser 42 and used as a guiding track groove 44. Thus a glass master disk 46 is finished. Then it is possible to increase the contact area of an optical disk and to improve the inter-layer bonding intensity of the disk.
