Title: Treatment of copper circuit on inner layer circuit board
Inventor: ARAI TAKAFUMI
IPC: H05K3/46
Filed: 1989-04-15
Abstract: PURPOSE:To improve adhesion between a copper circuit and prepreg resin and prevent the development of a halo phenomenon by removing an oxide coating on the surface of the copper circuit with an alkaline solution after performing oxidation treatment of the copper circuit which is provided on an inner layer circuit board. CONSTITUTION:After electric circuits are formed on the surface and rear of a laminated board which is a glass cloth base material-epoxy resin laminated board clad with copper foils on the both sides of the above board, both faces are made to become slightly rough by a belt sander. Then the solution of alkaline sodium chlorite is prepared at a temperature of 90 deg.C and an inner layer circuit board is immersed in the above solution for 10min. Then its circuit face is made to become rough still more by performing oxidation treatment of the surface of the copper circuit and a cupric oxide film is formed as well. Subsequently, this circuit board is immersed in a 15% of aqueous ammonium for 30min. at a temperature of 30 deg.C to dissolve the cupric oxide film. Then its cupric oxide film is removed and the above board is washed with water and is dried. Thus surface treatment of the copper circuit not only improves adhesion between the copper circuit and prepreg region but also prevents the development of a halo phenomenon.

Title: Program encoder and recorder
Inventor: BRUELS WILHELMUS HENDRIKUS ALF
IPC: H04N19/61
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To convert a program signal with a specified duration time to compressed data in such a way that a total amount of the compressed data is set within a usable data space and (subjective) quality in a program after restructuring is set to be almost constant. SOLUTION: When the program with the specified duration time is converted into the compressed data and recorded in an information carrier, the total amount of used data is required to be contained within the usable data space, which is difficult to be predicted in a variable bit rate compression such as an MPEG-2 system video signal. The recoder is provided with a compressing unit 22 and controls the bit rate by depending on the remaining part of a vacant data space on the information carrier 1 and a remaining time of the program with a control input terminal 26 by a system controller 45 in encoding. When the parameter to control the bit rate is set in the compressing unit 22, complexity of the program conducted in the part where the system controller is encoded to the head of the program is considered.

Title: Rolling rolls and method for rolling steel sheet with them
Inventor: KANEKO HIDEYUKI
IPC: B21B31/18
Filed: 1990-04-10
Abstract: PURPOSE:To uniformize the thickness of a sheet and to improve the flatness by constituting the external diameters of the rolled parts of work rolls so that they are made smaller than the external diameters of non-rolled parts and roll kisses can be generated on these non-rolled parts in a rolling time. CONSTITUTION:When the external diameters of the non-rolled parts 1b of the work rolls 1 larger than those of the rolled parts 1a, the roll kisses can be generated easily at the end parts of the work rolls 1. In this way, when reaction is generated by the roll kisses on the work rolls, the deflections of the work rolls are reduced by receiving reverse action by the reaction and a flatter extremely thin strip steel can be rolled. In the kiss rolling, as a roll gap is narrower, load is larger and the reaction is large, therefore, the parallelism between the upper and lower work rolls is improved and a rolled stock poor in snaking can be obtained. In this way, the thickness of the sheet is uniformized, the flatness is improved and the rolls can be adjusted easily.

Title: Loudspeaker unit
Inventor: SAKURAI SADAAKI
IPC: H04R9/00
Filed: 1979-07-27
Abstract: PURPOSE:To suppress the temperature rise of a magnetic circuit part as much as possible by coupling one terminal part of a heat pipe with the magnetic circuit part and then by protruding the other terminal part at the front face side of a diaphragm through a coil bobbin. CONSTITUTION:Heating part 25a of heat pipe 25 is inserted into and fixed in pole piece 13 of magntic circuit part 12 of speaker unit 11 and radiation part 25b is protruded to the surface side of diaphragm 19 by penetrating coil bobbin 17 through radiator 28. As a result, heat generated at circuit part 12 is radiated to the front face side of diaphragm 19 in the cycle of evaporation and liquefaction of a working liquid sealed in pipe 25 at a low pressure through heating part 25a and radiation part 25b, but since air alows into bobbin 17 by reciprocating through the vibration of diaphragm 19, radiation part 25b of pipe 25 is forcibly cooled by the air to alternate the evaporation and liquefaction of the working liquid at a high speed. Thus, the temperature rise of circuit part 12 is suppressed, so that audio pnput signals to coil 16 can greatly be increased.

Title: Vessel with lid support
Inventor: WATANABE RIYOUKICHI
IPC: A47J36/12
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a vessel with a lid support which prevents a lid from dripping off when the vessel is tilted to the maximum allowable degree of inclination for pouring. SOLUTION: A lid support 1 of a pendulum type, which can shift itself by its own weight in a direction in which the support 1 changes its position of a fixed degree under the effect of a gravitational force, is attached to a handle. When the vessel is inclined, the tip of the support 1 changes its position into a direction in which the gravitational force rests and sets itself in a standby position before the inclination is to such a degree that allows the lid to fall down. Thus the lid is prevented from falling down by leverage support.

Title: Device for controlling fuel injection quantity of multicylinder internal combustion engine
Inventor: MATSUSHITA SOICHI
IPC: F02D41/00
Filed: 1988-04-21
Abstract: PURPOSE:To control a fuel injection quantity with high accuracy irrespective of the magnitude of engine speed by increasing/reducing the fuel injection quantities of the whole cylinders in accordance with the magnitude of variation in the combustion pressure of one cylinder after adjusting output torques. CONSTITUTION:The differences in output torques between each cylinder are detected from the required times for explosion strokes calculated based on the output signals of a crank angle sensor 19 and a timer, in each control circuit 41. A fuel injection quantity is corrected so as to substantially remove the output torque differences to adjust the output torque of each cylinder. Then, the fuel injection quantities of the whole cylinders are increased/reduced in accordance with the variation in a combustion pressure from a combustion- pressure sensor provided on a first cylinder.

Title: Semiconductor integrated circuit device with lateral transistor
Inventor: SAIKAI HIROSHI
IPC: H01L29/73
Filed: 1978-08-08
Abstract: PURPOSE: To remarkably raise the various characteristics of a lateral transistor by raising the impurity density of a base layer in the range from a collector to an emitter.  
     CONSTITUTION: An N-epi layer 14 on a P-type Si substrate 11 is separated by P +  layers 13 and 15. An ion is implanted into the upper of an N + buried layer 12 and is processed in the high temperature N 2  gas to form an N + layer 18. Next, a P +  emitter 19 and collector 20 are selectively formed in the layer 18 and adjacent to that. Because a base impurity density distribution of a PNP lateral transistor formed by such a process becomes greater in the emitter region than in the collector region, a resistance r bb  is lowered, and an occurrence of a punch-through may be difficult in a narrow base width, therefore, BVCEO becomes great. Because an accelerating field is generated in the base layer, an hFE is increased and, when the base width is reduced, an fT is raised. In a combination of the transistor having a high performance with a vertical type transistor, a mutual compensated IC device having a high performance and a high resistance to voltage can be obtained.
