Inventor: KISHIMOTO MASAHIRO
IPC: B23F21/28
Filed: 1983-07-07
Abstract: PURPOSE:To make it possible to conduct a shaving finish with a high degree of accuracy to an outer ring gear even having a small number of teeth, by utilizing an inner ring gear as a shaving cutter, and forming grooves on the both surfaces of each tooth in the direction orthogonal to the axis. CONSTITUTION:An inner ring gear type shaving cutter is arranged such that a cutting blade section 2 is inserted into an L-like cross-sectioned shape holder 1a, and is fastened by a plurality of bolts 3 and a ring-like holder 1b. Both surfaces of each one of teeth constituting the cutting blade section 2 are formed with a plurality of grooves 4 extending along the direction orthogonal to the axis. Withi this arrangement, the contact ratio between the shaving cutter and a gear to be cut may be made large so that the meshing between them is aimed at being stabilized, thereby the precise involute tooth shape of the cutter can be copied onto the gear to be cut.

Title: Chopper type stepping-up/down dc-dc converter
Inventor: HENMI TOKUYUKI
IPC: H02M3/155
Filed: 1992-05-15
Abstract: PURPOSE:To reduce a voltage loss by equipping a diode-loss reduction means for bypassing a current, which flows through a diode at the time of step-down operation, to a bypass transistor(Tr). CONSTITUTION:At the time of step-up operation, a step-down switching element (DS) 1 is turned ON, a step-up switching element(US) 5 is controlled by a driving signal 5d in ON-time ratio, and output voltage V0 rising in inverse proportion to the OFF-time ratio of the US5 is supplied to a load 11. When the comparison voltage of a switching controller 22 is higher than a reference voltage, ON- command 21d is not outputted, Tr 21 is turned OFF, and a smoothing capacitor 6 is prevented from discharging on the US5 side by a series diode 3 so that step-up operation is performed. At the time of step-down operation, the US5 is turned OFF, the DS1 is controlled in ON-time ratio by a driving signal 1d, and the output voltage V0 lowering in proportion to the ON-time ratio of the DS1 is supplied to the load 11. When the comparison voltage of the switching controller 22 is lower than the reference voltage, the Tr21 having received the ON-command 21d is turned ON and a current 15 flowing through a series diode 31 is bypassed to the Tr21 side.

The light is further inputted to the directional optical coupling means 5, from which the light is outputted to the port different from the light input port from the white light source 1.  The output light of the white light source 1 is subjected to spectral segmentation at the time this light passes the optical demultiplexing means 6. The spontaneously relieved light is removed from this light at the time when the light is amplified by the reflection type optical amplifier means 7 and passes the optical demultiplexing means 6 again.

Title: Manufacture of mesh bag
Inventor: TANZO JUNJI
IPC: B01D29/11
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To improve the fitting properties to a garbage basket or the like by introducing an elastic yarn through an upper end opening part to be interlooped and cutting at a connected part on the side of a mesh bag, when the bag with an opening on the upper end is interlooped in such a manner that the sides are connected together using a double needle warp knitting machine with a synthetic fiber as a material. SOLUTION: The mesh bag 1 is interlooped in such a state that the sides 6 of the bag with an opening part 2 on the upper end are connected together using a double needle warp knitting machine 5 with a synthetic fiber as a material. In this case, first an elastic yarn 3 is introduced through a position for the opening 2 on the upper end to be interlooped and then is cut at a part where the sides 6 are connected together to complete a single mesh bag 1. Further the mesh bag 1 is set inside a garbage basket and the upper end of the drip bag 1 is replicated to the outside from the upper end of the basket to fit the bag 1 to the basket. Thus the fitting properties of the mesh bag 1 to the garbage basket are improved as the elastic yarn 3 is introduced through the upper end of the mesh cage.  The foreign particle is prevented from falling from inside the mesh bag 1 by narrowing the opening 2 on the upper end with the elastic yarn 3.

Abstract: PURPOSE:To contrive to improve operating properties by making the operation, for converting the number of issued labels into the predetermined number of such labels, unnecessary through totalizing the prices and weights of commodities and the number of issued labels in a memory in accordance with the completion of counting of the commodities by counting means. CONSTITUTION:When an operator puts a first commodity A placed on a predetermined tare in a weighting part 1, the load is converted into an electric information in the weighting part 1 and into count data in A/D converter 23 and read in a main processor 21. Accordingly, the tare is deducted from load data in the weighting part 1 so that a net weight is obtained, and a price is computed from the net weight and unit price. Then, a weight, price and count value are indicated as the number of issued labels by an indicator 15. Such process is conducted also for succeeding commodities B, C and the weights and prices of the commodities A, B, C are totalized in the corresponding total area of an article number file R1. Thus, it is unnecessary to convert the number of issued labels into the predetermined number of such labels for operating it and to contrive to improve operating properties.

Title: Controller of heater
Inventor: UENO YOSHIYUKI
IPC: H05B3/00
Filed: 1982-07-15
Abstract: PURPOSE:To prolong the life of a heater, by arranging a temperature switch to be opened at the upper limit temperature or more and a high power setter, and a temperature switch to be closed at the upper limit temperature or more and a low power setter in parallel, respectively. CONSTITUTION:An object to be heated is heated at high electric power W1 when the peripheral temperature is maximum B, but excess heat more than necessary causes the upper limit TH of a controlling range to be exceeded. However, a temperature switch 23a is opened and a temperature switch 23b is closed immediately after exceeding the upper limit TH, so that low electric power W2 is supplied to the heater and the object to be heated is heated by a low output. Since sufficient heat to be required at the maximum of peripheral temperature is supplied, the temperature of the object to be heated is reduced because heat supplied from the initial status is finally reduced, and balanced status is kept in the control range.
