Title: Peak value detection circuit
Inventor: ISHIHARA MASAAKI
IPC: H03K5/1532
Filed: 1991-01-09
Abstract: PURPOSE:To prevent the base voltage in the transistor constituting the emitter- follower provided on the output step in the charging control part in the peak value detection circuit from falling too much at the time of the hold mode. CONSTITUTION:When the input signal voltage is greater than the peak voltage held by the peak voltage holding circuit and the operation mode becomes the hold mode, the base voltage in the transistor in the emitter-follower circuit provided on the output step in the charging control circuit is clamped by the voltage clamp means. Thus, the excessive falling of the base voltage of the transistor in the said emitter-follower circuit at the time of the hold mode is prevented.

Title: Joining structure of synthetic resin hollow body
Inventor: NISHIDA MICHITOKU
IPC: B29L22/00
Filed: 1991-01-09
Abstract: PURPOSE:To prevent a deviation of confronting surfaces of half-split bodies due to contraction and a leak of joining resin through a space in the confronting surfaces in a two stage molding method, by a method wherein a hollow and protrusion which are positioned to each other are formed respectively in the confronting surfaces of the half-split bodies. CONSTITUTION:Protrusions 43 which are meshed with hollow parts 33, projected upward and possess a triangular section are formed in a longitudinal direction into confronting surfaces between flange parts 41, 42, fitted into mold surfaces at the time of curing of resin in the primary molding of the half-split bodies 3, 4 and confronting surfaces 30, 40 are prevented from falling into inward. Then under their confronting state, they are meshed with each other and the confronting surfaces 30, 40 are held at a fixed confronting position without having a deviation. Therefore, spaces 34, 44 of flanges 31, 41, which are confronted with each other, form a casting space R1 where it is damped up inwardly. Since the confronted surfaces abut almost completely against each other, it is eliminated that molten resin B is leaked through the space when the molten resin B is cast through the sprue and a hollow body product having a favorable external appearance is obtained.

After that, the cut-off edge of the sheet 73 is rewound so that the cur-off edge is kept hanging under he wound sheet 73. The sheet-spread-out position is changed for the other. The sheet 73 is then spread out from the latter sheet- spread-out position in the prescribed direction of spreading-out while the reverse of obverse side of the sheet is located as upside. Such operations are repeated. The handling of the wound sheet 73 is thus simplified and facilitated.

Title: Hot-air heater
Inventor: HONDA YUKIO
IPC: H05B3/14
Filed: 1991-01-14
Abstract: PURPOSE:To enable acting quickly in preventing an accident such as a fire, in the use of a ceramic heater-element of negative characteristics, by connecting an auxiliary heater-element of positive characteristic to the ceramic heater- element of negative characteristics in series and by providing close to the auxiliary heater-element a switching device which is sensitive to heat and functions to cut off power supply to the kinds of heater-elements. CONSTITUTION:When a blower 5 has stopped working during operation or when the air volume of the blower has dropped because of some trouble in the passageway 3 for air, the electric current flowing in a ceramic heater- element 1 increases because a ceramic of negative characteristic is in use for the heater-element. This increase of the current makes an auxiliary heater- element 6 of positive characteristic heat up so rapidly as to show an increase in power consumption in a larger ratio than the ceramic heater-element 1; the heating of the auxiliary heater-element 6 accelerates the heating of a thermostat 7 and, as a result, a switching device acts to cut off power to the ceramic heater-element 1 of negative characteristic. Thus the heating of the ceramic heater-element 1 of negative characteristic can be acted against quickly to prevent it from developing into accident such as a fire.
