A telephone call selector in a telephone which comprises a memory circuit for storing a plurality of telephone numbers; an automatic dialing device operable to read out one of the telephone numbers from the memory circuit and to output a dialed signal representative of such one of the telephone numbers; a comparator for comparing a number, corresponding to a DTMF signal transmitted from a calling party subsequent to the receipt of a ringing signal generated from a local telephone of the calling party, with any one of identifier codes; and a loudspeaker device for emitting ringing sounds when the the number corresponding to the DTMF signal coincides with such one of the identifier codes. The telephone numbers stored in the memory circuit are utilized as the respective identifier codes.

A structure for locking a display case door including a door handle, a pair of support members supporting the end portions of the handle, a lower support member of which has a through hole, and a locking piece extendably and retractably below the lower support member and having a through hole capable of facing the though hole of the lower support member so that an arm of a lock can be inserted through the both through holes. Since the locking piece can be positioned below and within the lower support member, it does not become any obstruction to the customers. A structure for treating dew drops dropped from a door of a display case including a tray for catching the dropped dew drops, a dew drops scattering inhibitor plate on the front portion of the tray, and a guide path on the rear portion of the tray and sloped down toward a machine room. The dropped dew drops are prevented from being scattered by the inhibitor plate and the collected water quickly and efficiently guided into the machine room by the sloped guide path. A structure for easily attaching without screws a packing support plate to a display case frame at a door position wherein the display case frame has grooves at least on its both inner side surfaces and the packing support plate has flange portions to be inserted into the grooves.

According to the party selecting circuit arrangement of a telephone of the present invention, an owner of the telephone can avoid a mischievous call or an erroneous call since it is so arranged that a call sound is discharged through the speaker only when the number given by the party other than the owner of the telephone is coincident with the telephone number stored as a secret number in the memory circuit of the telephone. Moreover, the party selecting circuit arrangement according to the present invention enables the owner of the telephone to identify the other party before he or she answers the call since an indicating element which indicates the number of the auto-dialing operation button provided correspondingly to the memory circuit storing the secret telephone number is turned on only at the above-described time.

A display case is provided with a compartment which stores merchandise for display and is divided into at least two chambers by a partition plate to enable storing different types of merchandise, each of which types is to be held under a predetermined temperature. These chambers communicate with one another through a communication gap which is defined between the partition plate and the window of the case and the opening and closing of the gap is controlled by a sealing mechanism to vary the temperature conditions within each chamber. The sealing mechanism includes a sealing element which is movably engaged with the partition plate and a retaining element is fastened on the partition plate to hold the selected position of the sealing element. Thus, the opening and closing control of the gap is easily operated without interfering with the visibility of the merchandise.

The mass production system disclosed herein provides a method for producing highly aromatic petroleum pitch, comprising, preheating a liquefied petroleum residuum to a temperature of 450.degree.-520.degree. C. by passing the same through a tubular heater for 0.5-15 minutes, feeding the preheated residuum into a reaction vessel, thermally cracking the same by introducing an inert gas heated to a temperature of 400.degree.-2,000.degree. C. through a heating furnace into the reaction vessel for direct contact with the residuum for 0.5-10 hours, and adjusting to be coincident the ratio of the number of feeding flow lines for the preheated residuum from the tubular heater into the reaction vessels to the total number of reaction vessels with the ratio of the charging time .theta.C required for charging one reaction vessel with one feeding flow of preheated residuum to the total time .theta.T required for carrying out one batch of the thermal cracking in one reaction vessel.
