Title: Hybrid integrated circuit and manufacture thereof
Inventor: MATSUZAKI TOSHIO
IPC: H05K1/16
Filed: 1988-01-29
Abstract: PURPOSE:To obtain highly integrated and high-density hybrid integrated circuit, by forming a thick film resistance on a thick film pattern and layer insulating membrane including a polyimide layer having a window for trimming the thick film resistance. CONSTITUTION:A thick film pattern 2a and a thick film resistance 5 are formed on a heat-resisting insulating substrate 1 of such material as alumina and overcoating glass 7 is formed on said substrate 1 including on said thick film resistance 5 but except the portion not being in contact with an upper thin film pattern 4 to form a thick film pattern 2. A polyimide layer 3a is formed as layer insulating membrane 3 between said overcoating glass 7 and the upper thin film pattern 4. After forming the polyimide layer 3a, a through hole 8 is formed in a demanded portion of said polyimide layer 3a and a window 6 for trimming the thick film resistance is made. The window 6 serves to prevent polyimide from melting to avoid a danger of burning in a process of the laser trimming of the thick film resistance 5 performed after for preventing the resistance value from unstably charging. This enables the precise trimming of the thick film resistance 5 to obtain an accurate and compact hybrid integrated circuit although said resistance is a lower layer.

Title: Semiconductor laser and manufacture thereof
Inventor: FURUKAWA RYOZO
IPC: H01S5/00
Filed: 1987-01-31
Abstract: PURPOSE:To suppress an increase of an oscillation threshold current by causing a region of an optical guide layer that is situated at both end sides of a semiconductor laser resonator to grow into a more swelling region that a center side region. CONSTITUTION:The thickness of an optical guide layer 41 becomes thick at both end face sides 41b and becomes thinner than both end face parts between both end faces 41c. Accordingly, light energy confined in a part of an active layer corresponding to both end parts of a resonator becomes low and light energy confined in the part of the active layer corresponding to the resonator between both ends becomes high. Then and faces of the resonator, needless to say, not only may improve critical oscillation output value that may result in an optical damage but also lowers an oscillation threshold current.

Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To shorten a time necessary for warming up by forming the closed magnetic circuit of the magnetic flux of a permanent magnet by a side magnetic circuit member, the permanent magnet and a fixing part roller. SOLUTION: Inside the fixing part roller 9, an induction heating coil 4 is formed in a cylindrical part, and in the gap part, a coil bobbin 1 with inserted-in permanent magnet and the side magnetic circuit members 5 and 6 which are fixed to the supporting end parts of the coil bobbin 1 are stored. The magnetic flux of the permanent magnet 2 is formed to the closed magnetic circuit passing through the side magnetic circuit member 5, the fixing part roller 9 and the side magnetic circuit member 6 and coming back to the permanent magnet 2. Only by making a current intermittently flow in the coil 4, the magnetic flux quantity inside the fixing part roller 9 is easily varied. Thus, it is possible to generate an eddy current inside the fixing part roller 9 and to generate Joule heat inside the fixing part roller 9.  Besides, by making a current intermittently flow in the coil 4 under a switching operation, the heat generated at the fixing part roller 9 is uniformly diffused on the surface of a fixing roller 10 in a short time.

Title: Sheet material cutting method
Inventor: FUJINAKA HIDEO
IPC: B26D11/00
Filed: 1991-02-15
Abstract: PURPOSE:To efficiently cut sheet materials with high dimensional accuracy. CONSTITUTION:Sheet material 2 fed on a carrier line 1 passes a pair of shearing machines 3 disposed in the mutually opposed state along the conveyed direction of the sheet material 2. The sheet material 2 then passes a pair of shearing machines 4 disposed in the mutually opposed state with the carrier line 1 held in between. Both lateral ends, parallel to the conveyed direction, of the sheet material 2 are cut by the shearing machine pair 4. The degree of parallelization in the cut edges of the sheet material 2 is improved because of being cut by two pairs of shearing machines 3, 4 simultaneously. This enables the improvement of both productivity and product quality, and the neat line structure easy to control can be obtained without requiring the installation of a reversing device for reversing the sheet material 2 in the carrier line 1.

IPC: B23K11/24
Filed: 1979-02-27
Abstract: PURPOSE: To change the voltage between electrodes, assure the quality of the low resistance weld zone and improve working efficiency by controlling the pressing force between the electrodes.  
     CONSTITUTION: During supplying of welding current, the maximum value thereof is outputted from a waveform representative point holding circuit 6 at every half wave of the inter-electrode voltage detected by a voltage detecting circuit 5. It is compared momentarily with the voltage based on the reference voltage curve generated by a reference voltage generating circuit 7 by a differential amplifier 8 and a pressing force control unit 9 is operated by the signal Vd corresponding to this voltage difference to control the pressing force between a moving electrode 2a and a fixed electrode 2b by way of a piston 3, so that the differential voltage is made zero. Namely, when the pressing force is increased, the inter-electrode voltage decreases and when the pressing force is made to decreased pressure, the inter-electrode voltage increases. The inter-electrode voltage is so controlled as to change in conformity with the reference voltage curve over the current supply period, whereby the good quality is obtained.

Title: Clock frequency divider
Inventor: HYON SHITSU KAN
IPC: H03K23/64
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To generate a clock which has a 50% duty cycle and cycles that are an odd multiple of those of an input clock by comparing the count value of the input clock with a 1st divisor obtained by dividing an input divisor by two and a 2nd divisor obtained by subtracting the 1st divisor from the input divisor alternately. SOLUTION: A clock frequency division control part 31 alternates the 1st divisor (divsr 1) and 2nd divisor (divisr 2) from an odd-multiple cycle signal output part 30 to count the input clock clk i and is reset and recounts the clock when the count value reaches the 1st or 2nd divisor to output a reset signal clk rst. A clock frequency division signal output part 32 undergoes transition of the output with a combination of positive or negative edges of clk rst and clk i. Consequently, clk i can be divided into a clock clk O which has a 50% duty cycle and has cycles extended to an odd multiple.

Title: Multiple resonance type speaker system
Inventor: OBARA RINTARO
IPC: H04R1/28
Filed: 1989-01-31
Abstract: PURPOSE:To obtain a compact and thin speaker which can satisfactorily reproduce the low-pitched sound bands by preparing spirally plural acoustic tubes of different lengths around the speaker and at the inside of a cover member which covers closely the rear side of a baffle plate attached with the speaker and turning the open ends of the acoustic tubes to the front or side face of the baffle plate. CONSTITUTION:A speaker 2 is set apart from the center of a baffle plate 1. A cover member 3 covers the speaker 2 and closes the entire rear side of the plate 1. Then plural circular or spiral acoustic tubes 5-9 of different lengths are formed around the speaker 2 in the member 3 by means of the partitioning plates 4 having the height approximately equal to the height of the speaker 2. Thus the sounds are circularly or spirally discharged through those tubes 5-9. The other end of each of tubes 5-9 is opened to the single side of the member 3. Therefore the reproduced sounds received from the speaker 2 are discharged through the front face of the plate 1 and also discharged through the single side face of the plate 1 via the tubes 5-9. In this case, the reproduced sounds discharged from the side face of the plate 1 cause the multiple resonance phenomena due to the different lengths of tubes 5-9. Thus the medium/low- pitched sound bands can be satisfactorily reproduced.
