Title: Device for measuring friction coefficient of magnetic head
Inventor: TANAKA YOSHITO
IPC: G11B5/455
Filed: 1988-07-18
Abstract: PURPOSE:To estimate the sliding of a head and a disk in a short time by detecting the fine displacement in the vertical direction and the horizontal direction of flat springs which support the magnetic head by a force detection element. CONSTITUTION:When a medium 15 rotates, a frictional force works between the magnetic head 8 and the medium 15 and the flat springs 5 and 6 are finely displaced in the horizontal direction which is a rotating direction. By pressing the medium 15 with the magnetic head 8, the flat springs 1 and 2 are finely displaced up and down in a direction vertical to the medium 15. By disposing distortion gauges 12, 13, 10 and 11 which are the force detection elements on said springs 5, 6, 1 and 2, the forces in the horizontal direction and the vertical direction against the medium can be detected. The friction coefficient between the head and the medium can be directly obtained from the force in the horizontal direction (frictional force) and the force in the vertical direction (pressing force). Thus, the durability and the sliding of the magnetic head and the medium can be estimated in a short time.

Title: Electronically controlled fuel injection device for internal combustion engine
Inventor: ARAKI AKIHIKO
IPC: F02D41/00
Filed: 1987-07-17
Abstract: PURPOSE:To avoid the excessiveness of increase correction by providing a limiting means which limits the increase correction of fuel when an engine load is in a predetermined value or less in an acceleration condition just after the deceleration operation not performing the stop control of fuel injection, executed when the engine is placed in a predetermined deceleration operation condition, but performing the fuel injection. CONSTITUTION:Being based on an engine load by a detecting means A, a corresponding correction coefficient is referred to a correction coefficient referring means C from a memory means B, and being based on the referred correction coefficient, a fuel injection amount, set in a setting means E, is corrected in an increase correcting means F in accordance with an engine operative condition when it is detected in an acceleration condition detecting means D. Being based on this fuel injection amount, a fuel injection valve H is driven and controlled by a control means G. When the predetermined deceleration condition is detected in a detecting means I, opening driving of the fuel injection valve H is stopped by a fuel injection stopping means J. In the injection device thus obtained, it provides a correction coefficient limiting means L which sets a correction coefficient to be decreased and corrected in accordance with a decrease of engine temperature, detected in a temperature detecting means K, when an engine is in acceleration just after deceleration operation except the detected deceleration condition further when an engine load is in a predetermined value or less.

Title: Semiconductor device
Inventor: IMAI HAJIME
IPC: H01L21/60
Filed: 1982-10-08
Abstract: PURPOSE:To prevent a bonding melting agent reaching the bonding area of a lead wire from flowing by forming grooves at an interval from a semiconductor element placing region to the bonding area of a lead wire on the surface of a heat sink for the semiconductor element. CONSTITUTION:A film 5 made of a dioxidized silicon is formed on the surface of a wafer 4. Then, the film 5 on the groove forming region is removed, and grooves 6 are formed by a wet etching method using a mixed solution of a fluoric acid and a nitric acid with the remaining film 5 as a mask. Thereafter, the remaining film 5 is removed, and metallized layers 7, 7' are formed on both side surfaces of the wafer 4. A bonding melting agent 8 is insularly formed on the semiconductor element placing region on the wafer 4, and divided by dicing into heat sinks. In this manner, even if the agent 8 is fluidized when the element is placed, it is prevented by the grooves 5 formed on the heat sink, thereby preventing it from reaching the bonding region 10 of the lead wire.

Abstract: PURPOSE:To prevent the formation of scale to a hot coil while the hot coil is allowed to cool by depositing a sealing material to the edge parts of the hot coil right after coiling to shut off the edge parts from the outdoor air. CONSTITUTION:The hot strip S emitted from a finishing mill 10 is cooled with water in a cooler 11 and is coiled by a coiler 12a as the hot coil 7.

Title: Battery life checker
Inventor: NAKAMURA ATSUHITO
IPC: G01R31/36
Filed: 1988-07-15
Abstract: PURPOSE:To calculate the residual capacity of a battery after the deterioration degree of the battery is estimated by using the elapse of the terminal voltage of the battery outputted from a memory means, a preliminarily formed deterioration judge chart and a residual capacity chart. CONSTITUTION:At first, the clock outputted from a clock supply part 31 is applied to a discharge time setting part 32 which in turn counts a charge period by the first counter to cut off the second counter and an FF. The output of the FF drives a relay RL to change over a battery 2 to a discharge circuit R at a contact rl but the second counter starts the counting of a discharge time. At this point of time, a writing order is applied to the terminal WE of a memory 51 and the terminal voltage of the battery 1 is converted to a digital signal by an A/D converter 52 to be written in the predetermined address of the memory 51. Next, when a switch SW4 is closed, output enable is applied to a terminal OE and the content of the memory 51 is successively outputted to be converted to an analogue signal by a D/A converter 53 to be displayed on an analogue meter.

Abstract: PURPOSE:To reduce the concn. of acetaldehyde left in a container to thereby improve flavor retention, by incorporating a predetermined amount of a specified thermoplastic polyamide in a material for a container made of a thermoplastic polyester mainly composed of ethylene terephthalate units. CONSTITUTION:100pts.wt. thermoplastic polyester (A) mainly composed of ethylene terephthalate units is mixed with 5X10<-7>-10pts.wt. thermoplastic polyamide (B) having a terminal amino group concn. of 0.05-50mmol/100g of resin (e.g., nylon 6). The resin mixture is molded to obtain the title container. The component B acts as an agent for lowering the concn. of acetaldehyde. Acetaldehyde formed by the heat decomposition of polyethylene terephthalate is trapped by the terminal amino group of the component B to thereby reduce the concn. of acetaldehyde in the container. Thus, the flavor retention of contents can be improved.

Title: Multistage dust collecting element
Inventor: MOGI KANJI
IPC: B03C3/47
Filed: 1994-07-29
Abstract: PURPOSE:To make the improvement of dust collecting efficiency and the restraint of pressure loss be compatible with each other by holding each dust collecting part body by a frame body with a clearance allowing the flow of air from a dust collecting air flow passage on the upstream side to that on the downstream side being divided. CONSTITUTION:A top plate frame 223 and a bottom plate frame 229 are set in the air flow direction so that they may each be longer than electrode plates 211, 212 by a dimension B at both the ends. In this way, between a dust collecting air flow passage PS of one dust collecting part body 210 and a dust collecting air flow passage PS of the other dust collecting body 210, a clearance C is divided at the time of continuous setting. By this constitution, the dust collecting air flow passages PS of the dust collecting bodies 210, 210 each communicate with the dust collecting flow passages PS through the clearance C. As a result, air that has passed through an ionizing part 10 is introduced into the air flow passage PS on the downstream side from the air flow passage PS on the upstream side through the clearance C. Therefore, pressure loss is effectively restrained even when a clearance 53 of the air flow passage PS is narrow.
