Inventor: HORIUCHI HITOSHI
IPC: H01L21/68
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a CSP.IC(chip size package IC) in which the production cost can be reduced. SOLUTION: The CSP.IC 10 is provided with a plurality of electrode pads 13 formed on a first major surface of a chip 11 while being wire bonded with outer terminals 14 and resin molded under a state where the upper part of a group of external terminals 14 is exposed from a resin sealing film 15 onto the first major surface. A bump 16 is wire bonded onto the external terminal 14. The CSP.IC is mounted on a board 40 through flip-chip connection. Consequently, the package can be suppressed equal in size with the chip and since no printed wiring board nor film carrier is required for forming the resin sealing film and the outer terminal, production cost can be suppressed. Production cost of the CSP.IC can be reduced furthermore because no special process is required.

Filed: 1993-08-06
Abstract: PURPOSE:To control the operation of a membrane separation apparatus by rapidly detecting a leak even when a separation membrane is damaged and to suppress the contamination of a transmitted component or the lowering of the concn. rate of a component to be conc. CONSTITUTION:When a first separation membrane 1 is damaged, the fluid to be treated leaked from the separation membrane 1 of a first module 2 is supplied to a second module 4 equipped with a second separation membrane 3 having an average pore size larger than that of the first separation membrane 1. The coarse component in the fluid to be treated blocks up the pores of the second separation membrane 3 and, on the supply side and/or transmission side of the second separation membrane 3, pressure or a flow rate varies corresponding to the leak of the fluid to be treated. This variation is detected by a pressure detection means 13 or a flow rate detection means and a control means controls the supply of the fluid to the first module 2 and/or the second module 4 in response to the detection signal from the detection means. Therefore, the leak is rapidly detected and the contamination of a transmitted component or the lowering of the concn. rate of a component to be conc. as the leak of the fluid to be treated can be suppressed.

Inventor: KODAMA YOSHIZO
IPC: G11B15/665
Filed: 1988-08-30
Abstract: PURPOSE:To obtain a cassette holder mechanism with simple constitution capable of setting a cassette holder to a prescribed height on a main chassis by forming an engagement part and an engaged part respectively engaged with each other to a part corresponding to the cassette holder and the main chassis. CONSTITUTION:When a reel chassis 2 reaches the moving end of a head cylinder 11 while a cassette holder 20 is loaded to the descending end, an engagement part of the cassette holder 20 engages with the engaged part of the main chassis 1. Through the engagement, the height of the cassette holder 20 on the main chassis 1 is regulated. Since the entire head cylinder 11 or most of it is accommodated in the internal space of the cassette holder 20 on the reel chassis 2, the inside of the cassette holder 20 is shielded magnetically and the head cylinder 11 is protected from an external magnetic noise. Thus, the height of the cassette holder is regulated with simple constitution and the recording and reproducing performance is improved at the same time.

Title: Input circuit
Inventor: IGARASHI HATSUHIDE
IPC: H03K17/24
Filed: 1987-08-28
Abstract: PURPOSE:To prevent malfunction caused at the momentary trailing of a power voltage by devising it that an input threshold value at a low power voltage is not decreased from a degree or below. CONSTITUTION:The input is connected to an NMOSFETM1 whose source and drain are short-circuited, the source of the M1 is connected to a source of a PMOSFETM2, the gate is connected to ground, the drain is connected to ground via a load element L1, the input of an inverter I1 is connected to the drain of the M2 and the output of the inverter is used as the output of the tilted input circuit. The logical threshold value of the inverter I1 varies in proportion to the power voltage. A component causing a voltage drop exists between the input and the inverter I1. The one component is the FETM2 and the voltage of the threshold voltage always appears between the drain and source. The other component is the FET M2, and since the gate is connected to ground, the FET is not turned on so long as a voltage exceeding the threshold value of the M2 is not applied between the source and gate. Thus, the M1 is subject to back gate bias, the threshold value is increased further and the logic threshold value of the input circuit is not lowered than a voltage even with a low power supply voltage employed.

Title: Toner delivery part connecting/separating mechanism
Inventor: KASAI SHINICHI
IPC: G03G15/08
Filed: 1988-08-30
Abstract: PURPOSE:To segment the title mechanism into a supplying side and a receiving side and to separate both of them without occurring contamination to toner even when a joint toner route is filled with toner by constituting the mechanism of two adhered thin slide plates which also serve as the covers of the supplying side and the receiving side at the time of segmenting them. CONSTITUTION:In the case of separating the supplying side 3 from the receiving side 4 at the toner delivery part, a slide member formed of the two adhered thin slide plates 11 and 12 is rocked so as to segment toner filled in the toner route of the toner delivery part and closes the toner route of the toner delivery part. Moreover, when the supplying side 3 and the receiving side 4 are separated, two thin slide plates 11 and 12 are held as the covers of the supplying side 3 and the receiving side 4. As a result, the interior and exterior of the toner route are not directly exposed and there is no occurrence of toner contamination to the exterior. Thus, both of the supplying side and the receiving side are surely separated without occurring toner contamination to the exterior even when the joint is filled with toner.

Title: Oil-hydraulic damper
Inventor: NAKADA ETSUROU
IPC: F16F9/34
Filed: 1982-12-09
Abstract: PURPOSE:To suppress the amplitude throughout a wide range of vibration applying frequency efficiently by allowing the oil to flow through a by-pass oil-line provided in a rotor and thereby reducing the damping force in the set angular frequency range of a vibratory system equipped with a damping means. CONSTITUTION:In a range of angular frequency omega as omegacr1<omega<=omega1, a rotor 13 rotates when the oil passes through a torque generating groove 29, and an oil line 23 is put in communication with a one 18a. In another range as omega1<omega<= omegacr2, the rotor 13 rotates in the opposite direction to put the oil line 23 in communication with a one 18b, and the oil flows by-passing a leaf valve 9 to cause drop of the damping force. In a range of angular frequency omega as omegacr2<omega<=omegacr3, the rotational angles of the rotors 13 and 14 become below the set angular displacement thetacr, so that communication of oil lines is shut off. In a range of angular frequency omega as omegacr3<omega<=omegam, rotation of the rotor 14 puts an oil line 19a in communication with a one 24, and the oil by-passes the leaf valve 9 again.
