Title: Loud speaker
Inventor: SHIMAMURA NAOKI
IPC: H04R9/02
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a loud speaker with thin profile that is suitable for repro ducing a sound with a medium and high frequency band. SOLUTION: A plurality of air gaps 2b extended in a direction of the Y axis are formed to a cylinder 2a of an outer yoke 2 with a magnetic gap G with an inner yoke 5 inbetween. A voice coil 6 is connected to an inner circumferential cylinder 8a of a connection member 8, and an inner circumferential edge 9a of a diaphragm 9 is connected to an outer circumferential cylinder 8b of the connection member 8. A plurality of connection parts 8c interconnects the inner circumferential cylinder 8a and the outer circumferential cylinder 8b so as to allow the connection parts 8c to enter inside of the air gap 2b of the outer yoke 2. The inner circumferential edge 9a of the diaphragm 9 is connected to the connection member 8 at a position lower than an outer circumferential part 9b.  Thus, the diaphragm 9 is formed to be conical or pyramidal and the stiffness in the vibration direction is enhanced to allow the speaker to reproduce sound at medium and high frequencies.

Abstract: PURPOSE:To reduce the processing time for teaching and improve the operation capability by subjecting the rear of a printed circuit board in a standard posture wherein the component mounting surface is arranged upward to an excessive lead cutting process. CONSTITUTION:A sample printed circuit board 7 on which electronic components are mounted by soldering is supplied to the starting end of a conveyer belt 8 in a standard posture wherein the component mounting surface is arranged upward and transferred until it is positioned by a stopper 12 and held and fixed by a locking arm 14 at the spot of positioning. Then a movable frame 4 is stood 90 degrees by a lever 22. In this state, the rear of a board holding mechanism 1 can be visually observed easily through the opening of the top plate 4a of the movable frame 4. In this state, an X-Y table 3, revolving motor 16 and a nipper 2 are operated to memorize the procedure necessary for cutting the excessive leads protruding from the rear of the printed board 7. After teaching is completed, the movable frame 4 is returned to the original horizontal position and, thereafter, the excessive leads are automatically cut by controlling the operation of the nipper 2 in accordance with the predetermined procedure given by the teaching.

Title: Instrument for measuring effective staying value of entering and leaving visitor to facility or the like
Inventor: YAMADA MASAKAZU
IPC: G07C9/00
Filed: 1988-03-29
Abstract: PURPOSE:To measure the effective staying value of visitor of a facility by resetting the content of a register to the added result of an adder which takes the sum of the output of a staying visitor number output device and the content of the register and displaying the output of the register whenever the adder outputs its addition output. CONSTITUTION:Entering and leaving signals from an entering/leaving visitor detector 1 are impressed upon a staying visitor number output device 2 where the signals are respectively counted and the difference in both count values, namely, the number of visitors currently staying in a store (the difference between Curves N and L at a specific time T) is outputted. An adder 41 adds the output of the output device 2 and the content of a register 40 to each other whenever periodical signals are outputted from a timer 3. In other words, the adder 41 integrates the difference Y between the values of the Curves N and L at the time T in the time base direction and resets the content of the register 40 to the sum of the output of the output device 2 and content of the register 40. Therefore, effective data which have a strong correlative relation with the sales are obtained.

Title: Telephone system, telephone set used for the system and abbreviation number registration method
Inventor: SAITO KEIJI
IPC: H04M3/44
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To simply register an abbreviation number even by a person unskillful of the operation. SOLUTION: The user of the telephone set 10 informs in advance a set of an abbreviation number and a telephone number corresponding to it to an agency. The agency uses an agent device 14 to make a phone call to the telephone set of a registration object party to register the abbreviation number. In this case, the agent device 14 sends a registration switching signal and registration data of the abbreviation number. The telephone set 10 uses a reception section 105 to receive a registration mode switching signal to set a registration mode of the abbreviation number.  In this state, registration data are received to allow an abbreviation number registration section 104 to convert the registration data into a data form according to the registration operation specific to the telephone set and the abbreviation number registration section 104 applies registration processing of the abbreviation number to an abbreviation number storage section 101 based on the registration data after the conversion.

Abstract: PROBLEM TO BE SOLVED: To obtain a joined body of ceramic-metal having high hardness of metal surface and excellent in abrasion resistance by carrying out specific treatment after joining due to brazing in the joined body constituted by joining ceramics to metal with a brazing material. SOLUTION: Ceramic is joined to a metal by brazing and the joined body is subjected to nitridation treatment by gas soft nitridation method which is a surface hardening method for diffusing and permeating nitrogen into the metal (e.g. iron or iron alloy). Si3 N4 or a composite ceramic obtained by dispersing 0.5-10vol.% TiN, SiC and W or Mo into a matrix of Si3 N4 is used as the ceramic and Ag-Cu-Ti-based or Ag-Cu-In-Ti-based silver solder is used as a brazing material. The joined body is obtained by joining the ceramic to the metal by brazing in vacuum or nitrogen atmosphere and subjecting the joined body to nitridation treatment. Thereby, residual stress produced by joining is relaxed and deformation of joined body is made small and hardness of the metal surface is improved.
