Title: Space heating device
Inventor: MIKI MASAYOSHI
IPC: F24C15/06
Filed: 1987-04-09
Abstract: PURPOSE:To make it possible to freely color a radiation permeable body and to prevent the performance of diffusion of radiant heat from a heat source from being reduced by providing a heat source, a reflection plate and the radiation permeable body positioned on the front surface of the heat source and colored in a lustrous color. CONSTITUTION:A radiation permeable body 7 is formed by accommodating an aluminum honeycomb shaped molding 9 into a metal frame 8. The honeycomb shaped molding 9 is colored in a lustrous color by ordinary Alumite working. Radiant heat generated from an electric heater 5 is reflected by a reflection plate 6 and passes through the radiation permeable body 7. Upon this occasion, since the surface of the honeycomb shaped molding 9 is lustrous, the radiant heat is diffused by a diffused reflection. Therefore, the radiant heat can be radiated without affecting the user and can afford a sufficient space heating feeling to the user.

Title: Digital audio signal encoding/decoding device
Inventor: JOFU HIROO
IPC: H03M1/00
Filed: 1989-04-07
Abstract: PURPOSE:To prevent the generation of distortion due to an inclined overload by analyzing an input signal string at every finite section, and deciding the frequency characteristic of a prediction filter with linear phase characteristic and the quantizing characteristic of an adaptive quantizer based on an analyzed result. CONSTITUTION:A device can function as a pre-filter with the linear phase characteristic by decomposing a digital audio input signal with finite work length to a band-pass signal, analyzing the band-pass signal at every finite section, deciding a factor to decide the gain of each passing band, and adding it after weighing the band-pass signal according to the factor. In other words, a synthesis circuit 7 synthesizes each band-pass component to an entire band- pass component by changing the gain at every band-pass component by using factor arrangement obtained from a factor decision circuit 3, and functions as the prediction filter of an adaptive difference encoder circuit 4, and outputs a signal in which a filter processing is applied on an inputted digital audio signal. In such a way, it is possible to evade the generation of distortion due to the inclined overload and to eliminate a harsh noise in an auditory sense.

Title: Electrostatic printing method and apparatus and image carrier film
Inventor: NAKAMURA MINORU
IPC: B41M5/382
Filed: 1989-04-06
Abstract: PURPOSE:To obtain an electrostatic printing apparatus capable of printing a large number of printing papers by a method wherein an insulating film is selectively heated to release the insulating film of a part to be heated from a conductive membrane and the insulating film remaining on the conductive membrane is charged to electrostatically adhere toner to the charged film. CONSTITUTION:When a thermal head 7 is selectively heated along a original image, the insulating film 5C of the heated part is transferred to a transfer film 5D. Therefore, when the transfer film 5D is released from an image carrier film 5, the insulating film 5C having the shape corresponding to the image of a non-heated part not heated by the thermal head 7 remains on a conductive membrane 5B. When the insulating film 5c is positively charged in this state by a charging corotron 53, the upper surface of the conductive membrane 5B is not charged because said membrane 5B is earthed and only the 'negative image' due to the insulating film 5C is positively charged. Therefore, toner 54P is not adhered to the 'negative image' positively charged and adhered to a part where the insulating film 5C is absent, that is, the 'positive image' heated by the thermal head 7 by coulomb force.

Title: Method and equipment for detecting alignment mark
Inventor: KAMON KAZUYA
IPC: G06T1/00
Filed: 1992-04-09
Abstract: PURPOSE:To obtain an alignment mark detection method and a detection equipment which can detect, with high precision, an alignment mark formed on a semiconductor wafer. CONSTITUTION:While a semiconductor wafer 1 is irradiated with laser beams 10X, 10Y composed of polarization components oscillating in the direction perpendicular to diffraction grating rows, the wafer 1 is moved along the direction perpendicular to the grating lattice rows, and the signal intensity of the diffracted light is obtained by receiving the diffract light from the semiconductor wafer 1. On the basis of the signal intensity, an X-mark 3X and a Y-mark 3Y which function as an alignment mark are detected. Thereby the signal intensity of the diffracted light at a position deviated from the diffraction grating rows is restrained to be low, and the signal intensity waveform of the diffracted light approaches an ideal waveform. Hence the peak position of the signal intensity can be precisely obtained, so that the coordinates of the X-mark and the Y-mark which function as the alignment mark can be detected with high precision.

Abstract: PURPOSE:To improve the supercharge efficiency under low speed and transiency by providing a check valve device for blocking the counterflow to an exhaust turbo supercharger side between an intake path collecting section in the downstream of both superchargers and a compressor for an exhaust turbo supercharger. CONSTITUTION:Under light load low rotation of engine 1, an electromagnetic clutch 20 is turned off to open a relief/bypass valve 20 so as to take the air naturally through a bypath 21 into the engine 1. When the engine 1 is acceleration from light load low or intermediate rotation, the electromagnetic clutch 20 is turned on to close the relief/bypass valve 22, so as to supercharge the air through a second branch path 10b to the engine 1 by means of a mechanical supercharger 19. Since the supercharged intake air from the mechanical supercharger 19 is blocked from counter flowing to a compressor 16a side of an exhaust turbo supercharger 16 by means of a check valve 18, lowering of the supercharged pressure of the mechanical supercharger 19 or lowering of the supercharged pressure of the exhaust turbo supercharger 16 due to the counterflow can be prevented.
