Title: Floating head slider and magnetic disk device using the same
Inventor: YAMADA TADAHARU
IPC: G11B21/21
Filed: 1994-02-28
Abstract: PURPOSE:To keep an approximately constant floating amt. from the inner circumference to the outer circumference of a disk even in a low floating amt. and to enable the manufacture in the conventional machining method at low cost. CONSTITUTION:The floating head slider is made of an Al2O3-TiC material, having two floating surfaces 11 and head elements 12 on their rear end sides. A part of the floating surface 11 on the side of an air inflow end 18 is formed with a slant surface 15. Moreover, a step 17 is formed on the side of the air inflow end 18 of the floating surface 11.

Title: Consumable electrode type arc welding method
Inventor: FUJIMURA HIROSHI
IPC: B23K9/12
Filed: 1984-02-20
Abstract: PURPOSE:To stabilize an arc and to obtain a beautiful bead having no welding defects by changing the supply speed of a welding wire in accordance with the migrating period of a molten metal in such a way that an inertial force to transfer the molten metal toward materials to be welded is generated. CONSTITUTION:A welding wire 32 is melted by a welding arc 311 to form a molten metal 312. The wire 32 is fed toward materials 34 to be welded at the same instant when the metal 312 is deposited on the tip of the wire 32 and therefore the inertia toward the materials 34 is applied to the metal 312 as well. When the wire 32 moves in the direction parting from the materials 34, the molten metal 312 is forcibly detached and transferred by the inertia. More specifically, the molten metal 312 is detached surely from the wire 32 by receiving not only the effect by the pinch effect but also the effect of the inertia and is thus transferred to the materials 34.

Title: Sound volume controller
Inventor: SASAKI MIKIO
IPC: H03G3/02
Filed: 1987-02-10
Abstract: PURPOSE:To improve the sound volume control characteristic at low sound volume by providing a 1st A/D converter receiving an input data signal and a 2nd D/A converter using an output voltage of the 1st D/A converter as a reference voltage to convert the input data signal into an analog voltage and using the output voltage of the 2nd converter thereby controlling the amplitude of the input signal. CONSTITUTION:A D/A converter 22 converts an input data signal into an analog voltage signal. A D/A converter 23 uses an output voltage of the converter 22 as a reference voltage to convert the input data signal into an analog voltage as the output. A sound volume control circuit 21 controls the amplitude of the input signal based on the output voltage of the converter 23. Thus, the output voltage of the converter 23 is decided by the reference voltage varied by the input data signal and the input data signal itself. As a result, smoother sound volume change is realized at low sound volume.

IPC: G06F13/36
Filed: 1982-02-25
Abstract: PURPOSE:To reduce the number of interface lines between devices, by dividing control data and answer data into plural blocks to transfer them. CONSTITUTION:When a request to send control data is generated, a CPU1 sets a transmission/reception switching line to the transmission mode. In order to send the 1st block of the control data, the CPU1 sends the 1st block data to a data line, sets a transfer word number line to the 1st block display and sends a transmission synchronous signal. In the same manner, the CPU1 sends the 2nd block data to the data line, sets up the transfer word number line to the 2nd block display and sends a transmission synchronous signal in order to send the 2nd block. Thus the CPU1 divides the control data consisting of 32 bits into two blocks each of which consisting of 16 bits to send them to speed path equipment.

Title: Manufacture of ultrafine formed resin film
Inventor: KIMURA KAZUSHI
IPC: B29C47/00
Filed: 1989-02-10
Abstract: PURPOSE:To contrive an improvement in productivity by enabling continuous operation for a long period of time, by a method wherein a chemical forming agent is used by fining the same and a fined porous adsorbent is added similarly to the chemical foaming agent. CONSTITUTION:Matters obtained by collecting by a cyclone pulverized bodies of an extent of 0.1-2mum of a chemical foaming agent and porous adsorbent by processing them with a dry crusher are mixed by a proper quantity to each other and used by mixing with powdery synthetic resin. The pulverized body of the porous adsorbent serves as prevention of moisture adsorption for the pulverized body of the chemical foaming agent. When raw materials entered into a melting extruding machine through a hopper 2, they are heated and melted gradually by a heater 4 according to transfer with a screw 3. Then although the foaming agent generates gas through dissolution and the gas is accumulated on the inside, it becomes that the gas is adsorbed and held by the porous adsorbent and in this instance, the inside is under a state where it is high pressure and high temperature. Although a molten and foamed material is filtered with a sheet mesh 6 and extruded in a filmy state, in that moment, the material is exposed under the normal pressure from high pressure, the gas which is kept adsorbed and held by the porous adsorbent is separated suddenly and foaming is accelerated.
